I recently picked up the Voigtländer Ultron 40/2 (seen left, above) to use as my primary lens on the Pentax MX. Smaller lens to go with a smaller body, naturally. 43mm is the standard focal length for 135 format photography — not 50mm (blame the folks in Wetzlar for that one). My favorite standard range primes have always been in 40-45mm. With this in mind, my options for a small prime were basically the Ultron, the old Pentax 40/2.8 pancake, or the Pentax Limited 43/1.9. The Limited is a beautiful lens, and I still want to get one some day, but it doesn’t seem much smaller than a normal Pentax standard, and I simply can’t afford it. The 40/2.8 pancake demands high prices, but it’s not the sharpest thing in the world… I still want to get one some day, because it’s tiny, but not until I find a good deal.

The Ultron is larger than a pancake, but smaller than a standard Pentax prime. Feel of the focus is the best I have felt on any lens I have ever touched, hands down. Aperture is the same terrible combination of full- and half-stop clicks as a genuine Pentax lens. The aperture ring is a bit smooth, and takes some getting used to. Lens is solid and heavy; heavier than the Pentax 50/2. Image quality is excellent, the lens is insanely sharp edge-to-edge. It does exhibit more distortion than I would expect (at both the focal length and the price point), but this is generally not noticeable, and correctable in post.

A few final observations: The CV uses aspheric elements… I do not know if these are plastic, hybrid, or glass. I doubt glass, due to cost. I doubt plastic due to weight. So, I have to guess hybrid. CV only includes a Leica-sized lens cap, to go on the hood. This cap is incredibly thick, plus the addition of the hood, and your small lens just got considerably beefier. I use a slim Pentax (F?) edge-squeeze type cap instead. The CV has 9 curved aperture blades, which results in round bokeh at any setting. If you value sunstars over decent bokeh, I guess this lens isn’t for you — personally, I’ll take the bokeh. Speaking of bokeh, while it won’t look horrifically polygonal on this lens, it does get a little ringy and is not necessarily my favorite. Optical design is 6 elements (one aspheric) in 5 groups on the Ultron, 5 in 5 on the 50/2, 5 in 4 on the 40/2.8 pancake, and 7 in 6 on the 43/1.9 Limited.

Canon Dial 35 2

This review is part of my photo reference set on Flickr. Clicking the photo above will take you to the photo page on Flickr, with pretty much the same review, but very detailed notes about the camera on the photo itself.

This here is a Canon Dial 35 2. Mine was distributed by Bell & Howell, and is branded as a Bell & Howell Dial 35. Before the Dial 35 2, Canon released the Dial 35, which Bell & Howell branded as the Bell & Howell / Canon Dial 35. So that’s what they’re called, but what are they?

Well, they’re half-frame 135 cameras with shutter priority or metered manual operation. They have wind-up clockwork motors for film advance and rewind. Plenty of other half-frame cameras exist, but most stick to the traditional camera layout that everyone is used to. Depending on how you shoot, this is a good or a bad thing — because it means that your standard orientation is going to be portrait. The Dial 35, with its odd layout shoots landscape when oriented ‘normally,’ which is my main draw to the camera.

The camera has decent ergonomics. Zone-focusing is achieved with a lever running along the top of the lens. Surrounding the lens is the shutter speed adjustment, with speeds from 1/30-1/250. Shutter release is on the lower right (from the user’s perspective) of the lens. Above the release is a small knob for aperture setting. Push the knob into the body, and the camera operates in Tv automatic mode. Pull it out, and turn it to adjust the aperture (f/2.8-22), metering inside the finder. Oddly, the shutter speeds are visible only outside the finder on the shutter speed dial, and aperture numbers are visible only inside the finder, with no representation on the knob itself.

While the camera feels really solid and has decent optics, it also has one fatal flaw: the clockwork advance mechanism. I ran one roll of film through mine, and it started acting very sticky when I went to rewind it. I thought it was done, but opened the back prematurely and fogged the roll. And then, after that, the mechanism stopped working altogether. This is a common issue, and the mechanism is not simple to get to, and less simple to repair. Some people have reported success merely by slipping penetrating lubricants inside — I plan to try this, but it’s low priority. For now, I have a neat, useless camera which I at least got to shoot one roll of film through.

Size comparison: Pentax K vs Pentax M bodies

This little article is part of my photo reference set on Flickr. Clicking the photo above will take you to the photo page on Flickr, with quite a few notes about the cameras on the photo itself.

When I was looking to move from a Pentax KM to a Pentax MX, I was unable to find any good photos comparing the sizes of the two series of bodies. So, after I received my MX and before I gave my KM to a friend, I shot them side-by-side at some straightforward angles in case this information is ever valuable to anybody else.

As far as other layout differences between the K-series and the MX (other M-series have even different layouts, being Av bodies), few are notable. K-series bodies either have no indicator (K1000), or a spin wheel to describe what sort of film is in the body. I prefer either of these to the memo holder of the MX, wherein one slides part of the box the film came in. I’ve never used these memo holders, I think they’re ugly and I think they’re awkward. Depth of field preview has been merged into the self-timer lever on the MX, which is a nice UI simplification. The ISO adjustment wheel (outer ring of shutter speed dial) on K-series bodies is of the sort that one lifts and rotates to adjust. On the MX, a tiny button on the shutter speed dial must be depressed, and then the outer ring turned to adjust the ISO. Which, unfortunately, only goes to 1600. Setting it is a real pain, though, compared to the old method… and I have tiny fingers! Finally, one of the biggest differences is match diode in the MX vs. match needle in the K-series. Personally, I choose diodes… Less precise, but also less fragile. Love the finder on that camera, and the LEDs are the icing on the cake.
