Ever since I started shooting DSLRs with APS-C sized sensors I have struggled to find the perfect go-to lens for the majority of my photos. I love the speed and image quality of my old A series 50mm f/1.7 but the lack of autofocus and relatively tight F0V (75mm equiv.) makes it less than ideal for a lot of my shooting. When my friend Stephen said he was sending me his DA 35mm f/2.8 Macro Limited to take for a spin I was pretty sure that it was going to be the lens I have been looking for. I had read all the reviews so I knew that it was a sharp lens with top-notch build quality. All that remained was for me to live with it for a few days…

Pros:

• Razor sharp starting at f/2.8.
• Virtually no flare and very low CAs or fringing.
• Wonderful bokeh (especially during macro use).
• Impeccable Limited build quality.
• Smaller and lighter than most 1:1 macro lenses.
• Durable*
• Ultra close focusing capability.
• Built-in lens hood.
• Excellent bang-for-the-buck.

*I didn’t test this lens’ durability but my friend Stephen did. Within minutes of opening the box he dropped it from a height of 1M onto concrete. The filter mount ring took the brunt of the impact (note silver filed away area in these shots) but the function of the lens was not otherwise affected. Wow!

Cons:

• Slow focusing due to extremely long focal range.
• Lack of focus limit switch (might correct previous point).
• Focus ring spins during autofocus operation.
• Included lens cap falls off too easily.
• Extremely limited stand-off distance at 1:1 magnification (read: “none”).
• Diffraction may be a problem above f/8 with non-macro shots.

Conclusion:

Turns out this is not the do-it-all lens I’ve been looking for. Now, before all you Pentaxians out there start accusing me of bashing Pentax again, let me explain…

The DA 35mm f/2.8 Macro Limited is one of the best macro lenses I have ever used. It absolutely blows everything away within 2 feet of the front of the lens. I love the natural look the 35mm (52.5mm equiv) FoV provides. I can easily see this being one of the best lenses available for shooting products in a studio setting. If I were still walking the floor at Asian electronics trade shows it would be my go-to lens (lots of close-up shots of products held in my hand). However, the things that make this lens so good at what it was designed to do also make it less than perfect for my everyday use. If your primary interest is up-close hand-held macro photography, look no further. Buy this lens. If, like me, you are thinking that this lens might double as a good medium focal length lens for everyday use, please read the rest of my review and decide for yourself:

Build Quality and Size:

Here we see the DA 35mm f/2.8 Macro Limited focused at infinity along side the standard 18-55mm Pentax kit lens…

and here we see the macro lens focused to its closest setting (0.139M)…

and here along side my old A series 50mm f/1.7 lens. The point here? This is a very compact lens. Even when extended for close-up focus. Also, even with the rock-solid aluminum casing it weighs slightly less than the plastic kit lens (7.6oz vs. 7.8oz). There is absolutely no excuse for not being able to find a place in your bag for this lens.

I mentioned the focus ring in the cons. The double row of knurled rings just below where it says “PENTAX-DA 1:2.8 35mm…” in the photo above is the focus ring. It is very nicely damped in manual mode and features Pentax’s nifty Quick-shift Focus System to allow focus fine tuning in AF mode. The double-height ring provides a great grip for your fingers during manual focusing. However, since it takes up so much of the 35’s diminutive body, you have to be careful not to grab it accidentally when holding the camera with two hands (left hand supporting lens) if you don’t want to loose a little skin off your finger tips ;-)

Otherwise, the build quality of this lens is superb. You’ll never question the $480 price tag once you handle one for the first time.

Image Quality:

The resolving power of this lens is amazing. I’m sure my old 10MP K10D isn’t even coming close to getting the most out of this baby. I’m not going to get into resolution specifics here. There are plenty of other websites that can confirm what I experienced first hand: this is one of (if not the) sharpest lenses you can hang on your K Mount. Here are a few shots I took with it on my Flickr page.

The nine bladed aperture provides wonderful round bokeh at all aperture settings.

It also provides nice 18 pointed starbursts when stopped down for long exposure night shots (if you are so inclined to use it for such things). They are not quite a clean as the ones that come off of the DA* 16-50 f/2.8 but they are certainly an improvement over the kit lens.

The DA 35mm Macro has a built-in retractable lens hood. Without the hood this lens produces almost no flare. Compare the example above with this similar one shot with the DA* 16-50 f/2.8:

Even though Pentax thoughtfully includes an excellent built-in lens hood with the DA 35mm Macro it doesn’t need one!

Handling:

The DA 35mm Macro requires you to get very close to your subjects to achieve maximum magnification. Here is the shot I took above while focusing at 1:1 on my kit lens with the 35 Macro:

Very close indeed. This is fine for shooting flowers, products and other static and aproachable subjects. If you want to shoot creatures that might not appreciate a lens pressed up in their face you might want to look elsewhere. The only real problem I had with this was the camera blocking light from my subjects. Being so close with the lens to the subject you’d pretty much need a studio and strobes to get enough light in there.

I’ve had experience with longer macro lenses that put you farther away from the subject and I have to say I prefer the up-close DA 35mm Macro. The wider FoV gives a more natural 3D look to the images and makes it easier to lock in focus while shooting hand-held.

This incredible focus range (infinity to 0.139M) is the DA 35 Macro’s Achilles heel. It is very deliberate and accurate when shooting macro but becomes slow and laborious when taking snap shots. If the camera misses the focus point it will usually run all the way to one extreme of the focal range and then back to the focus point where (hopefully) it will lock on. If not, it will continue on to the opposite end of the focus range before heading back to try again. On a normal lens this “focus hunting” can be a bit annoying as the lens “ziiiip-ziiiips” back and forth before locking focus. On the DA 35 Macro focus hunting goes more like “ziiiiiiiiiiiiiiiiiiiip, ziiiiiiiiiiiiiiip, ziiiiiip, ziiip-zip.” I missed a ton of snap shots with the kids while this lens oscillated back and forth the focus scale on me.

Don’t misunderstand me. I’m not saying the focus isn’t accurate. As all Pentaxians apparently already know, their DSLRs do not have the fastest autofocus system. The DA 35 Macro exacerbates this problem considerably. Its deliberate focusing is an important feature for shooting critical macro shots in controlled conditions but is also the main reason why it isn’t a replacement for standard lenses for every day use. IMO there’s nothing wrong with being good at what you do and sticking to it.

That being said, it is not to say that the DA 35mm Macro can’t be used for every day shooting. When more deliberate shooting is possible all the things that make this such a great macro lens also make it an excellent portrait lens. Most people do not recommend a lens this wide for portrait use. I found it to be great for portrait shots where you want the feeling of being up close and personal while getting a bit more of the scene into the shot for context. Like this:

Of course what’s working for me here most are the 35mm focal length and the sharpness. If you are willing to give up the macro performance there are other lenses that can likely better serve as wide angle portrait lenses.

The only head scratcher for me with the DA 35mm Macro is Pentax’s choice in lens cap. The included cap is machined from aluminum and velvet lined. While this gives it a distinctly premium look and feel, it kept falling off the lens while in my bag. Also, it is easily knocked off while the camera is hanging on your shoulder strap. When I buy one of these lenses I will add a spring clip style 49mm lens cap to my order.

So, the DA 35mm Macro does what it does and does it quite well. Just don’t expect it to do all things equally as well. If you need/want and excellent macro lens then you’d be hard pressed to do much better. If you are looking for a good normal lens for taking those every day shots do what I did and pick up an FA 35mm f/2 AL while you still can. It was a close call for me. I had $500 to spend so I could have gotten the macro lens, but I decided to go with the slightly faster FA lens instead. So far I am quite pleased with my decision- though I really miss the DA 35mm Macro’s build quality and ability to get in close. I can easily justify getting the DA 35mm Macro for use as a dedicated macro/studio lens later on to round out my lens collection.

Some sample shots I took with the DA 35mm Macro while testing it for this review.

About the shots for this post: I shot the studio shots for this post using Fuji’s new F200EXR point-and-shoot camera. I’m not a big fan of PnS cameras but this little wonder has definitely gotten my attention. These shots are straight out of the camera at ISO 800. The camera’s various manual controls allowed me to get the exposure and WB right while the high ISO capability meant I could still go hand-held to knock the shots out quickly. BTW, this shot of the F200EXR was taken with the DA 35mm Macro. See what I mean about it being ideal for product photography?

I’m a little concerned about the focus performance of my Pentax K10D DSLR. Before I get too far into it, let me  establish a little background first…

Two years ago I was looking for an upgrade to my then 2 year old Canon Digital Rebel XT (350D). I really didn’t have much more than the kit lens and a cheap-o EF 50mm f/1.8 II, so I didn’t feel too married to Canon. I did my research and decided the then new Pentax K10D represented a better value for the $1,800 I had to spend than the more expensive Canon 30D. So, I gave my Rebel to my sister-in-law and ordered up a K10D body, Sigma 18-50mm f/2.8 EX and Sigma 10-20mm EX from B&H Photo.

The ergonomics, features, IQ, and interface were all so much better than my old Rebel that there wasn’t much time for  retrospection. I embraced my new rig and started shooting like mad. Six months and 20K snaps later I had added the excellent DA* 50-135mm f/2.8 to my kit. To my surprise, Santa (in the form of my mom and step dad) gave me a $1,000 Wolf Camera gift certificate for Christmas 2007. Suddenly I found myself in a quandary.

You see, I had become somewhat smitten by the full frame Canon 5D we had at the office for the Marketing team I managed. It had always seemed so out of reach to me and now suddenly it was all-too-close. After a few days of agonizing over what to do, I ended up selling off my K10D kit to a co-worker friend and added the proceeds to my gift certificate. 2008 began with a brand new Canon 5D body (the $3,000 body was all I could afford). Fortunately, my old 50 1.8 was collecting dust in the bottom of a drawer so I was able to actually use the 5D while I saved up for some better glass.

It was hard to draw many comparisons between the 5D and K10D. They really are quite different cameras- with the 5D being much more like a 35mm film camera than a high-tech digital. Plus, the clunky old 50mm prime I started out with on the 5D really wasn’t anything like the Sigma EX zoom lenses I had had on my K10D. What I didn’t know was that I would decide to leave my six figure job in April to return to school and finish my undergraduate degree. This move required scaling back across the board and my beloved 5D (and all the L glass I hoped to own) suddenly seemed like an excessive luxury. I decided to sell it, my EF 50 f/1.8 II, and the EF 28 f/2.8 and EF 85 1.8 USM I had acquired on Craigslist and invest the proceeds into my college fund. For the first time in 7 years I was without a DSLR.

In September of last year my former co-worker felt pity for my situation and gave me back my old K10D with the kit lens off his new K20D! Since then I have been shooting like mad with the kit lens and a 20-year-old SMC-A 50mm f/1.7 manual focus lens I picked up off of eBay. In the past couple of months that former co-worker of mine has also shared his DA* 16-50 f/2.8 and DA 35mm f/2.8 Macro Limited lenses with me to test on my blog. I wasn’t too impressed by the 16-50 (see review) and my experience thus far with the 35mm macro has been mixed (review here).

While I was at PMA a few weeks ago I played around a bit with all the various cameras on display. Both Pentax and Canon had similar demo set-ups for their top-of-the-range telephoto lenses. While using the DA* 300mm f/4 in the bright tradeshow lighting I tried focusing on a subject standing a few meters away and the SDM motor woooshed close then dunk, da-dunk, “beep-beeped” into focus lock. I then swung the lens up and selected a far away subject- woooosh, dunk, dunk, da-dunk, “beep-beep”. Selecting a subject a few feet away from the second the DA* 300 went dunk, dunk, da-dunk, “beep-beep”. This all seemed quite normal to me. From my experience shooting both the DA* 50-135 f/2.8 and DA* 16-50 f/2.8 SDM equipped lenses.

Then, I moseyed over to the Canon booth where they had a very similar display set up with a 1D Mark III and EF 400mm f/2.8 L IS USM lens. Repeating the short-to-long focus test (this time with a much heavier f/2.8 lens) the Canon went woosh, “beep-beep” to the close subject then woosh, “beep-beep” to the far subject. Selecting a nearby subject to the far one I got bump, “beep-beep”. Surprised I tried several more times, panning the camera around and selecting subjects that were just out of focus. Each time I simply got bump, “beep-beep” as the subject popped into near instant focus. At the time I merely chalked this up to the near 10X cost difference between the two set-ups and continued on my way.

Fast forward a few weeks to yesterday and my niece’s 3rd birthday party. I found myself two-fisting my K10D with 35mm f/2.8 Macro Limited and my sister-in-law’s Canon Rebel XT with kit lens (my old camera) while capturing both indoor and outdoor birthday party action. I was immediately aware at how much faster the 4 year old Rebel was locking focus than my K10D was. It was almost exactly like the performance difference I had experienced at PMA.

While the kids were busy taking turns in the kayak (and out of decent photo range for any of my lenses) I took a moment to do a little non-scientific focus testing. I manually set both cameras to infinity focus, selected the center focus point, 35mm focal length (on the Canon) and (in bright sunlight) focused on my hand at around 18″ away, then on the far side of the lake (infinity), then back to a post about 6′ away with the 35mm Macro on the K10D and the 18-55mm kit lens on the Rebel XT. In all cases the Canon nailed the focus point with zero hunting… zip, “beep-beep”, ziiip, “beep-beep”, ziip, “beep-beep”. The Pentax however, struggled a bit. The focus test went weeeee, tick, tick, tick-tick, “beep-beep” for the close subject, then weeeeee, tick, tick-tick, “beep-beep” for the far subject. Then, the camera completely missed the post 6′ away and went weeeeeeeeeeee all the way to it’s closest focus distance than weeeeeeeee, tick, tick, tick-tick, “beep-beep” on the post. (To be fair, this is a macro lens).

Thinking that the Pentax 35mm Macro might have been to blame (which it was), I pulled out my Pentax 18-55 Mark I kit lens and repeated this test again. The results were nearly identical with the exception that the Pentax kit lens did not overshoot the post and merely ticked around a couple of times before locking focus. Also, the lighter less damped focus action on the kit lens did make it seem a tad snappier when focusing between the close subject and the far subject. Incidentally, this time to reach the correct focus distance was basically identical for both the Pentax and the Canon kit lenses. The exception being all the tick, tick, ticking the Pentax lenses did before locking focus. (In case you were wondering I also repeated a similar test inside under poorer lighting with the two kit lenses and got nearly identical results as outside).

Discussing this with my co-worker friend, he relayed the results of a similar test he decided to try with his K20D as follows:

I just did back to back comparisons of the K20d + FA 50/1.4 and my Rebel + EFII 50/1.8. In indirect sunlight, using the center focus point I swapped focus between the front hedge at about 10M away and my left hand outstretched.
The Canon will ziiiiip, stop, confirmation beep.
The Pentax ziiiiips from 10M to my hand quickly just like the Canon but then it quickly zips one (or two!) more times before focus confirmation… Almost like it has momentum from the first movement.
I’ve been fully aware of this (and failure to focus–maddening) but had assumed that after twenty years of screw-driven, TTL autofocus technology this was the best the world could do. Seems it’s the best Pentax can do.
IMHO this is the worst aspect of my K20d.

Keep in mind that his test was done with a state-of-the-art $1,000 K20D + FA 50mm f/1.4 vs a $300 6 year old Canon 300D + 50mm f/1.8 II eBay find.

In hindsight I realize now how many shots I have missed over the years with my Pentax due to its slow autofocus performance. The most frustrating part is that the vast majority of shots I’m missing are while the camera is tick, tick, ticking its way towards focus lock, not because it has mis-focused. Once it gets there it is generally just as accurate as any other camera I have used. I hope Pentax is listening and improves the performance of their next generation of DSLRs. In my opinion, this is much more important than live view, more megapixels, movie recording, higher frame rates, and/or higher ISO performance. Pentax’s DSLRs are some of the best values on the market. Bring the AF speed up to par with the competition would end a lot of arguments in Pentax’s favor.

What do you think?

PS- I excluded Nikon from this comparison because I have very limited experience with their modern DSLRs. However, I did borrow a friend’s D300 + 50mm f/1.8 to take some studio shots of my K10D for my DA* 16-50 f/2.8 review. The camera was set up to use all 50-something focus points in AI mode. Being unfamiliar with Nikon’s focus confirmation implementation I didn’t realize until after I was done shooting that when all those grey boxes popped up in the viewfinder that the camera had locked focus. In hindsight I now realize that it was happening so fast that I was unaware that the camera was focusing. To get my shots BTW, I ended up switching over to manual focus ;-)

UPDATE: First of all I want to make it clear that I am not suggesting that Pentax’s autofocus system is any less accurate than anyone else’s. It is clearly quite effective. Also, I fully understand that Pentax has to pick and choose where they spend their limited development funds and I am happy they put it where they have (weather sealing, in-body shake reduction, user oriented controls, etc). In fact, that is why I chose Pentax over the others in the first place. My main reason for publishing this article was to attempt to draw the same comparisons so many Pentax users have over the past few years in a more objective manner so that those who haven’t experienced the differences themselves could be more fully informed. Too many consumers buy products today based on too narrow a point of view and then blame the product when it doesn’t meet their expectations.

The surprise here is that the Fuji FinePix F100fd ended up the Editors’ choice. It seems that Fuji has come a lot closer than the Big Brands to solving the high ISO noise problems typically associated with digital p&s cameras’ tiny sensors. I have zero experience with Fuji cameras but at under $300 on Amazon I might have to give it a shot as well as revising my recommendations. Chime in the comments if you have any experience with the Fuji p&s cameras (or any other favorites).

UPDATE: Check out Stephen Woolverton’s Flickr set of high ISO shots from the F100fd he ran out and bought immediately after reading this blog post ;-) Absolutely amazing stuff. ISO 12,800 looks like my Pentax K10D DSLR @ 800. Maybe I should consider trading down…
