PMA 2009 is in the books. All in all it was a pretty lack-luster show for us enthusiasts. Following are a few more product findings, some observations and my conclusions about the show in general. Be sure to check out my Day 1 and Day 2 reports if you haven’t already.

Seahorse’s waterproof hard-sided equipment cases have all the features of the bigger brands at less than half the price. If and when I need one of these this will be the brand I’ll buy.

Hoya’s new HD filters promise to redifne the filter paradigm. I picked up a 77mm sample for testing. Unfortunately, I don’t presently have a lens with a 77mm element. I hear Pentax’s 16-50 f/2.8 DA* does…

Liquid Image’s scuba mask digital camera may look pretty retarded but it’s actually a one of the more clever ideas at the show. As a former certified scuba diver I can safely say that, unless underwater photography is your profession, a dedicated cost-effective solution like this makes a lot of sense. (Have you priced underwater DSLR housings lately?) The hands-free design is quite ingenious for sport divers as it eleimnates the usual fumbling with underwater cases. I get the idea behind the mask-mounted lights, but if it were me I’d pass on them and just carry an old fashioned hand-held dive light for those deep water shots.

Note to Tamrac: hire a design firm. Your bags are u-g-l-y!

“So you won’t look like a tourist.” I’m told that this OP/TECH neoprene camera cover is easy-on/easy-off. This looks to me like some kind of combination ED and S&M/bondage product.

Ladies, why confine your scrapbooking to dusty old books destined for life on a bookshelf? Why not carry your photos with you proudly displayed for everyone to see? Actually, now that I think of it, Braggables might be on to something. Louis Vuitton has got nothing on my girls.

Dust-Aid got a lot of attention for their new clear plastic film mirror box/sensor covers. I agree with them that their product could be an ideal solution for pros heading out on safari, but am skeptical about amateurs dropping $20 a pop for something this fragile.

A better $20 solution from Dust-Aid is their Dust-Aid Classic product. It features a special silicone pad that simply lifts dust off the sensor. This seems like such a better idea than just blowing dust around inside the mirror box where it’s likely to just end up back on the sensor.

By the way, Sigma has been sealing their mirror boxes for a while now. Why doesn’t anyone else do this?

Speaking of Sigma. Check out their 200-500 f/2.8 EX APO DG lens they had hiding around the side of their booth.

According to Sigma: “For the convenience of the photographer, focusing distances and focal lengths can be viewed on the lens’ built-in LCD panel.” That’s nice. Unfortunately, the $34,000 price tag does not include the stand needed to support this beast- you know, for the convenience of the photographer and all…

This bothers me somehow.

What exactly is it that Panasonic thinks we will be doing with their cameras?

I found it somewhat ironic that focus and zoom rings on Samsung’s versions of the Pentax lenses are a closer design match to Pentax’s old lenses than their new ones (old on the right, new in the middle and on the left):

In Conclusion:

The digital camera industry has reached a critical development point. Today’s cameras have made wonderful photography accessible to the masses. However, all the bells and whistles modern cameras now feature are making it harder for novice photographers to actually learn photography. It used to be that entry-level photographers would start off their learning experience with a fully manual 35mm SLR and then step up to more feature rich products as they developed their photographic skill and better understood how to make the most of the extra features. Today’s entry-level DSLRs have basically all the same features as the most advanced professional models. The problem is that, in an effort to make the entry-level cameras more approachable, even some of the most basic shooting settings are buried in a menu system and overridden by automatic settings. What has been lost is that critical connection between the photographer, the camera and the exposure triangle (aperture, shutter speed & ISO).

The result is that there are more and more people running around taking pictures with fancy cameras who have no idea why their pictures turn out the way they do. The problem is that they often quickly become frustrated when they realize there’s no creative preset for every type of picture they want to take. I have yet to see a “bokeh” preset for example. The solution that the camera industry seems to provide is new cameras with even more features. What I would like to see is the camera manufacturers use technology to build a camera with only the features that actually help people take better pictures while becoming better photographers. As an experienced product designer this is what I would do if given the chance:

• Put the aperture control ring back at the base of the lens but make it a “by wire” system that keeps the aperture open to maintain a bright viewfinder for composing the shot while providing feedback in the viewfinder. “A” setting provides automatic control.
• Dedicate a thumbwheel to shutter speed and index it so that it has dedicated and marked shutter speed stops like manual film cameras do. Again, provide digital feedback in the viewfinder and include an “A” setting.
• Dedicate a second dial to ISO control with similar feedback and an “A” setting. ISO range from 100 up to a usable 32,000 as seen on the the latest high end DSLRs.
• Include a front control dial dedicated to exposure compensation. Allow changes to steps and direction via the menu.
• Loose multi-point AF and just make the center focus point work damn well all the time.
• No built-in flash. Hot shoe mount only.
• Use the space saved by deleting the flash to make the viewfinder bigger, brighter and have 100% coverage.
• Dedicated on/off switch around the the shutter release button- not hidden on the back of the camera.
• In-body sensor shift image stabilization with auto-override for stabilized lenses.
• Simple multi-position switches for auto-focus and metering modes.
• Dedicated image review buttons (play, delete, zoom, info, navigation, etc.)
• Simplified menu structure- don’t waste space on things that don’t help take pictures like “slideshow” and “creative effects.”
• Include a dedicated B&W shooting mode (even for RAW). There’s something about knowing you’re shooting in B&W that causes you to look at composition differently.
• Maybe even make it a dedicated RAW format camera- sort of like shooting film you’re going to process yourself.
• Move the top-mounted LCD screen to a dedicated screen on the back (like Canon did on the original Digital Rebel) and don’t clutter up a whole 3″ LCD with graphics and too much information.
• Make it super responsive (menus, start-up, review, shutter lag, etc.) and fast (5+ frames per second).
• Wrap the whole thing in a mid-sized rugged metal weather sealed chassis.
• Include modular different sized rubber grip inserts to allow a custom fit to all hand sizes. Or perhaps you can go without a grip if you prefer.
• Price it all under $500 and bundle it with a 50mm f/1.8 (or faster) equivalent lens while making it compatible with all full frame and APS-C sized lenses offered by the manufacturer.

The interesting thing is that most of these features are already being done or have been done on one camera or another. Maybe if one of the big brands decides to follow my advice we’ll have something a bit more interesting to talk about next year. Something that reconnects the photographer with the camera and the whole photographic experience. Perhaps if I can find some free time I’ll mock-up a 3D CAD model to explore my ideas…

Day 2 I took another lap of the show floor looking for things I may have missed yesterday. Click through to see what I found.

This idea in some form or another showed up in several Asian vendors’ booths. The idea is simple: provide a remote display that uses the video out feed from cameras with live view. This version is wired to the camera and features an articulating screen. Others seen on the show floor featured wireless technology to transmit the video signal to a remote release. The basic idea is pretty clever but I have to wonder just how many people really need such a thing (voyeurs not withstanding).

CropLines is a specialty product that adds custom-designed crop lines to focus screens. They’re not particularly cheap (close to $200 per screen) but that is mostly due to the degree of handwork required. I’m thinking I could use one with square crop lines. If you print a lot of photos an 8 X 10 crop would also be useful. The focus screen pictured is for standardized studio portraits.

Those wily Germans at Novoflex have one-upped the tripod by adding a fourth leg. They call it the “Quadrapod”. Not content with adding an extra leg, they also made the whole thing modular. Each leg screws off to create monopods. Also, additional accessories can be attached to the head mechanism to further expand its usefulness:

Add two more mini legs and you have a packable table-top quadrapod. Add suction cups…

…and you can stick it to a window. In typical Germanic fashion, the build quality is second to none. I didn’t ask how much ’cause if you have to ask…

I figured if I was going to spend $15 on lunch I should get my money’s worth so I headed over to the Hilton to the Noodle Bar in the back of the Benihana restaurant for some Hong Kong style stir fry noodles.

Back to the show and I discovered Olympus’ cut-away version of their E3 DSLR. Is it just me or does this look more complicated than the Nikon D3 version from yesterday?

With the crowds dwindling I took a few moments to play with the Panasonic Lumix G1. It is quite a tidy little package though it feels a little on the plasticy side for my tastes. The electronic viewfinder (EVF) is quite strange for someone coming from a true SLR camera. The weirdest part was the fact that the EVF displays the exposure preview just like a PnS (point ‘n shoot) camera does. I can see this being sort of useful sometimes but could turn into a real turn-off as the image fluctuates back and forth looking for “proper” exposure. My guess is most users will just use the big LCD display on the pack like a PnS camera. I stand firm in my assertion that this camera (and others like it) are either pocket cameras that are too big to fit in a pocket or DSLRs that are too small to keep up with their larger brethren. BTW, I overheard a Panasonic employee boasting that their were a total of 6 lenses for the G1. Me, I’ll just keep carrying a PnS (an old Panasonic Lumix FX-07 actually) in my pocket and a real DSLR around my neck for the time being.

Finally, I wondered back to the Nikon booth to take a look at their new AF-S DX NIKKOR 35mm f/1.8G lens. Obviously, I didn’t get to take any sample photos with it but it looks and handles pretty nice. I’m sure at $200 Nikon will sell a ton of these. If you have a Nikon DX format camera (anything other than a D700 or D3) I suggest you look at this lens. Having shot fast fifties on both full frame and DX sensor cameras, I can safely say that a 35mm lens on a DX sensor camera (52.5mm equiv focal length) is much more useful than a 50mm lens (75mm equiv)  for everyday use.

Tomorrow I’m planning on making one more pass. I wouldn’t hold your breath in anticipation of any more great finds.

I thought 14mm was as wide as one could go on a full-frame lens. Imagine my surprise when Ken Rockwell posted his review of the extremely rare Nikon 13mm f/5.6 rectilinear fisheye. Check it out. No barrel distortion what so ever. It is truly amazing stuff.

Thanks, Ken!

It seems that many Flickrites out there are struggling to get good bokeh shots. The good news is that shooting bokeh is one of the easiest photographic techniques to learn. Unfortunately, it is also one of the hardest to master. Here I will attempt to get you started with the basics. You’ll have to do the mastery part on your own :-)

Bokeh (pronounced: “boke-aay” or “boke-uh”- I prefer the latter) is the out of focus or blurry areas of a photograph. Wikipedia has a much more detailed description of the definition of bokeh that’s worth a read. On Flickr I find most people use the term to specifically describe out of focus highlights in a photo. For the purposes of this how-to we’ll focus (pun intended) on out of focus highlight bokeh.

The photo above made the Front Page of Flickr’s Explore last week. I wish I could say that this was a difficult and challenging shot that called upon all of my skills as a photographer. The truth is this was one of the easiest shots I took that night. These small aperture long exposure shots were a lot more difficult to get right:

The secret to shooting bokeh lies in its definition: out of focus highlights. You need three things to shoot bokeh: pin point highlights, a large aperture and a short focal distance. When I say pin point highlights I mean small light sources. Trying to shoot a large area of light like a window or fluorescent light does not typically produce the type of bokeh “balls” that we are looking for here. Small lights like Christmas twinkle lights are an obvious source, but any light source that is far enough away will become infinitely small and can produce bokeh. I find street and car lights in the distance at night make wonderful bokeh.

Pentax-A 50mm f/1.7 SMC

Next, we need a large aperture. For the novice, the aperture is the opening in the lens that controls the amount of light that makes it through the lens and shutter to the film/sensor. The smaller the f number (or f-stop) the larger the opening. This is usually expressed as f/5.6, f/4, f/2.8, f/1.4, etc. Read more about aperture here.  Typically the larger the aperture the larger the bokeh. Fast lenses below f/2.8 like my 20 year old manual focus Pentax-A 50mm f/1.7 SMC are ideal for shooting bokeh (and is the lens I use for most of my bokeh shots on Fickr).

That is not to say that one can not get great bokeh using lenses with a smaller maximum aperture like the typical kit lenses sold with most entry level DSLRs. The trick is to make sure you are using the largest aperture possible (smallest f number). To do this I recommend switching your camera into Aperture Priority mode (typically labeled “A” or “Av” on the program mode dial) and dialing in the smallest f number possible. With most kit lenses this will be f/3.5. Here is another Explore bokeh photo of mine shot with my kit lens at f/3.5:

The other reason that you want the largest possible aperture your lens is capable of is to ensure that your bokeh is round and not faceted. You see, most lenses use 5-7 straight aperture blades to create the variable opening in the lens. Bokeh takes on the shape and size of the lens opening so smaller apertures will produce smaller, faceted and generally less pleasing bokeh. There are exceptions to this rule as most high end lenses use curved aperture blades that keep the aperture opening round at all f stops. However, if you’re shooting with a $1,500 Canon L series lens I trust you already know how to shoot bokeh ;-)

Bokeh shots at different aperture settings with this lens (mouse over for setting):

The last component to getting good bokeh shots is the focus distance used. I have found that the shorter the focus distance to the foreground subject, the better the background bokeh I will get. The idea is to get as much distance between the subject and the bokeh producing highlights. Also, the closer you are focused to the camera the shorter the depth of field (DOF) will be. This ensures those lights way off in the background will be nice and blurred out.

The focal length of the lens is also a consideration. Depth of field is basically a function of focal length, distance to subject and aperture. At a given aperture and distance longer focal lengths result in shorter DOF. A short DOF is what we need to effectively blur the background highlights to produce bokeh. Getting close to the foreground subject and zooming to the longest setting on your lens will likely put you where you need to be to capture killer bokeh.

Here we have an example of close focus on the foreground subject coupled with a wide open aperture and longer focal length to create bokeh from small lights in the background:

When I took this shot I was at the minimum focus distance for my 50mm 1.7 lens (about 18-20″). The white (gold colored here) twinkle lights were on another Christmas tree approximately 8-10′ behind the light bulb and branch I focused on. The other smaller colored bokeh highlights were from other lights on the same tree that I focused on.

TUTORIAL:

Now that I’ve rambled on ad nauseam about all the intricate details of capturing bokeh, let’s get on to the part where you actually go do it!

For DSLR users (point ‘n shooters will have to wait for another tutorial):

1. Set your camera to Aperture Priority mode (A or Av on the program dial).
2. Select the smallest possible aperture (f) number for your lens (should be ≤f/4).
3. Switch your camera to manual focus and manually adjust the focus to the closest setting.
4. Zoom your lens to somewhere around 50mm.
5. Find some nice points of light at a distance of 10′ or greater from the camera (your Christmas tree is the perfect subject this time of year).
6. Fire away!

If you get a shutter speed that’s too slow (ie: less than 1/30 second), try bumping the ISO up to 400 or more. If you do the Christmas tree thing what you should get is something like this:

Depending on how dark the background is (darker usually = better) you might have to dial in some exposure compensation to get your bokeh to really pop. This image looks like it came out fine without any, but I often have to dial in +2/3 to +1 EV for my 50mm 1.7 on my Pentax K10D.

Next, try putting a subject of some sort in front of the camera at the minimum focus distance (or there about) with the bokeh highlights in the background. It’ll take a little playing around with subject matter and lighting (both foreground and background) but in no time you should be shooting bokeh like a pro! For more examples, be sure to check out my bokehliscious set on Flickr.

Please let me know in comments if this is helpful to you and/or if you have any questions or suggestions. Also, feel free to post links of your bokeh attempts for everyone to enjoy. Thanks for stopping by.

Happy bokeh-ing!
