One day, I could do a pretty nice comparison between the FA 150, the 6x7 150mm and the 6x7 165mm f2.8 late (don't have the A 150). But somewhat busy just now...

Hi,

Lately I have been shopping Pentax 645 system stuff based around a 645D. This isn't my first medium format rodeo, but is my first foray into Pentax. I have a lighthouse shooting project in mind and think 200mm is what I want to use the most. I see A 200mm lenses really cheap all over. Thanks to some reading here, I know why. So, I bought an FA 200 today. Still pretty low cost at $150. I also have an FA 80-160 zoom in case I need something shorter and an A 300mm prime in case I need something longer. A previous owner added a tripod foot to the 300, and now that it has arrived, I see why it needed one.

Anyway, thanks to the folks in the thread for helping me choose which 200 to go after.

Welcome to Pentax, the forums and digital medium format. We are on similar paths. I just got a new to me 645Z last month. Didn't realize the 300 lacks a tripod foot. Would love to see a pic of your 300 with foot. Any idea where the foot was "borrowed" from?

Thanks,
barondla

I talked about tripod mounts for the A*300 in my review of the lens, including the telescope finder mounting ring that actually works. (And a Canon mounting foot that looked good but rang likes bell.)

By the way, it does depend on which 300 you get. The following does have a foot:
SMC pentax-FA* 645 300mm F4 ED [IF]

But these do not:
SMC Pentax-FA 645 300mm F5.6 ED [IF]
SMC Pentax-A* 645 300mm F4 ED [IF]

Unless, as others have said here, one is added as a custom job!


(And, in case you are considering 67 options, the SMC Pentax 67 / S-M-C Takumar / Super Takumar 6x7 300mm F4 does not have a foot, but the SMC Pentax-M* 67 300mm F4 ED [IF] does)

Thanks for the A*300 review, I've added a comment to the above link with a slightly different model number for the scope mounting rings (will report if they fit).

Given that the FA200 doesn't sound significantly better than my late 67 200, I've gone for a 6x7 150 rather than the FA150 (for double duty - P6x7 & D).

Good call. In fact, I don't even think the FA200 is better than the late 67 200. In my experience, the latter is the sharpest of the bunch (though still not stellar). I think you already have the best option available in the Pentax medium format 200mm line.

Hi,

The one on my A 300/4 is a homemade job done with a 3D printer (by the seller I bought it from). Solid enough if not all that pretty.

Update: The rings arrived today, they fit the 645 A*300/4 well (as previously described by Rick). I'm a bit wary of how tight to tighten the ring around the lens barrel - have to see how solid everything feels when set-up.

Thanks again Rick for this information.

Rob:
. The text on the label gives a good illustration of sharpness and contrast. My overall conclusion: there is little to choose between these lenses. The A is the weakest and FA and Fuji the best, but the differences are so slight as to be almost meaningless for real applications. An interesting effect that I don't understand: the Fuji and FA files show some sort of chromatic aliasing or aberration in the text that is absent in the files from the other lenses. All the text should be black, but the two mentioned lenses render some of the text red or blue.

Thanks for the illustrations. I have been thinking about getting a 200mm A and was glad to see your illustrations of each of the lenses. I use a P645N and thus film which I print under an enlarger so the answer to my question is hopefully that it doesn't apply but what I noticed in the picture was that what is clearly a white bottle has come out as pink in the A compared to the FA and for that matter as pink in the 15o-300mm zoom and the P 67 lens

Can I take it that this is an artefact of the scans and not caused by something in the A lens that would show up when using the RA4 process?

Thanks

Photos were taken under different lighting conditions. Pink tint was from tungsten light. I did not adjust WB; I was only comparing sharpness. Color rendition of the Pentax lenses is consistently good.

Thanks for the reply I thought there might be a simple explanation that would set my mind at ease and it has but I felt I had to ask to be sure

I own both, the 200mm fa is easy, the auto focusing is right on. the 200mm a is better than you think, with practice and careful focusing you can get tack sharp images.

Certainly when I switch to MF on my 75mm FA and use the green hexagonal as the signal that I have the correct focus and then switch to autofocus the green signal is spot on
