Trips to the park, the ol' SMC Pentax 50mm F1.4 goes on the K10.

Just such a great lens.

I agree as I have the same lens but on a K100D. Takes outstanding pictures!

BTW does someone know what FL to set the anti-shake to when using old manual full frame glass on a 2/3 frame Pentax? My "guess" is 1.5 x the lens FL as that is what the camera "sees" this lens as. So for example set camera to 75 (77) for the 50mm lens?

I am new here - great thread

No. A lens doesn't change its focal length just because it's put on a different camera. A 50mm lens is a 50mm lens, whether it's on a 6x9 or 6x6 or 645 or 135/FF or 135/HF (APS-C) or 110 or whatever. Forget you ever heard about "crop factors" and lens equivalents. For SR, just input the real focal length.

AF when anything in the frame is moving. MF when nothing is.
Other way around.

(To be truthful, I seldom use AF at all...)

Hi Guy's,
I have several AF lenses and find that I may as well be using a point and shoot. I must admit I find it challenging using MF lenses but it adds to the image when you get that one that really stands out.

I mainly use a M50 f1.4 on Kx, light and clear images.

so i've been doing some important shooting recently, for clients etc

and when you don't have the luxury of a missed shot, not having AF is really difficult, when you're taking photos of people with places to go, if the shot doesn't come out (and it's tricky to focus on those tiny pentamirrors) then calling the person back is embarrassing and annoying

I like shooting MF because it's fun- but when it's important, MF and manual exposure is tricky, quite a lot to think about when you're mind is more focussed on the interview you just did rather than the shot you grab at the end

I guess I'm one of the minority, I shoot AF all the time (99.9%). My eyes tire very quickly and I can't depend on MF for any length of time, so I've gotten to rely on AF, and this is just the way I have to shoot, even for macros.

I need accurate spot metering, and no obstructions in the center of the VF, so split image focusing screens are not an option for me. I did put a KatzEye in my DS, but overall, I found that it hindered more than helped. I shoot with TCs almost exclusively, so with the slower max apertures, split screen blackouts were just too common. All my other bodies have their OEM screens.

I do cheat a bit and use the F 1.7x AFA to limit AF focusing range and increase AF speed, and I will often use AF C to get shutter priority if this is to my advantage, especially for the macro stuff,. The AFA does require some manual prefocusing with tele lenses, but all my critical focusing is done by the AFA. The unique qualities of the AFA is probably the single most important reason for me to stick with Pentax, given my sight situation and the subjects I like to shoot.

I've had to experiment extensively with the AF system, and have gotten to know it pretty well. I chose to make it work for me, rather than get frustrated by it.

The only time I switch to MF is when I have a relatively stationary subject, have already obtained critical focus, and need to keep it locked for a significant length of time to get the pose I want. An example of this would be a Heron fishing. They stand stationary waiting to strike for many minutes at a time, but when a fish comes into range, the action occurs almost too quickly to react. I do use AF to gain the initial critical focus though. . .

I shoot mainly birds and small critters, BTW. AF works for me. . .

Great attitude and great pics for sure. I am trying to do the same with manual focus, so here's one more vote for a solid manual 1.4/50 (on K100D in my case). I am a freetime snapper and look for that special shot and accept skipping a lot of the rest. Here's my take, the already-mentioned Zeiss C/Y AE Planar 1.4/50 fiddled onto the K100D. The new PK version has the same lens scheme but the price is 700,-US-$ ?


f/1.4 ISO800 1/13s. no crop no pp on K100D


f/2? ISO200 1/2500s. + polarizer no pp no crop on K100D
