Yeah, they changed the shutter again later on. I don't think it makes a difference in quality -- they just wanted to have one set of parts that they could use in two different cameras. The faster sync speed of the FM2n makes it more desirable than the FM2, but all of the FM2n's are good. > 2. How does the 2/85 mm (MF) compare to the > 1.8/85mm ? Which one is older ? Which one > should I get ? The manual focus 85mm/f1.8 is older than the 85mm/f2. The f1.8 won't work on the FM2 unless it's converted to AI. It's probably worth the trouble though. It's an excellent lens. I heard/read that the 85mm/f2's contrast was deliberately reduced to make it a better portrait lens -- I don't know if it's true. If it is I'd pass on it. It's a lot easier to reduce contrast when using a lens with high definition than to increase it with a lens that lacks definition. The AF 85mm/f1.8 is probably the best 85mm of the lot. I borrowed one at the camera store once and took a few pictures out in the parking lot (I'm trying to decide whether to keep my old 85mm/f1.8, replace it with an AF 85mm/f1.8 or replace it with an 85mm/f1.4). The few pictures I shot with it are utterly perfect. Unless cost or the feel of the AF's manual focus rule it out, I'd recommend it over either the MF 85mm/f1.8 or 85mm/f2.0. > 3.

The f1.8 is a bit better, especially in terms of distortion. > 4. What should I know about buying a used MD12 > motor ? Any problems ? Nah. I've never seen a broken MD-11 or MD-12 -- But here's how it ought to behave so you can check it out: Put it on the camera set the shutter speed above 125 and fire a few frames in S (single) and C (continuous) modes to make sure the S/C switch is OK. The MD-12 winds immediately in both modes, the MD-11 waits for you to release the button before it winds in S mode. Then turn the motor off pull the camera's advance lever out and release the shutter with the release on the camera, push the cameras advance lever back in and turn the motor on -- it should wind immediately. With the 12, the camera's meter should come on when you partially depress the release on the motor, then turn off after a few seconds. The 11 turns the meter on whenever the motor is on. The only thing you need to avoid doing with the MD-12 and MD-11 (except on some older FMs that have a different switch for the motor) is taking a picture when the camera's advance lever is in the on position and the motor is also on. It tends to confuse the motor and you have to take the it off the camera, wind the film manually, and then put the motor back on. It helps if you mumble obscenities under your breath while doing this. I developed the unfortunate habit of doing that because my old FM has the motor switch around the shutter release, so the position of the advance lever has no effect on how the motor works. I always left the lever pulled out so I could get to the shutter speed dial easily. 20 years later I still do it at least once in every roll of film I shoot with my (somewhat rarely used) FM2n. FWIW, my first MD-11 is still cranking away with utter regularity after pulling close to a thousand rolls of film through three different cameras over the last 20 years. I've never even sent it off to be cleaned/inspected. I have had to replace the batteries in it a couple of times though ;O) -Don
