Pentax M 50mm 1.7

Shot these today with my newest lens, Pentax M50mm1.7, a manual focus, manual apeture 50mm prime lens. Quite challenging to use, but the colors are awesome.

Summer's a good time for swimmin'.

If you don't get confirmation, it means the AF sensor thinks you didn't actually achieve focus. note only the central sensor is active with MF lenses. But there are no relevant settings or mdoes to worry about - the focus indicator (green hexagon) *will* come on when the sensor thinks focus has been achieved.

Marc,

Are you saying that my photos are out of focus? That's been the biggest difficulty with the M lens, getting tack-sharp action photos. Any suggestions? Pre-focus on a spot? Catch-in-focus (though I'm not sure what that is)?

Your photos seem indeed to be out of focus. Practice is key for manual focus. I usually watch for some fine detail in the area where I want to focus and I then just try to get that detail as sharp as possible - there's usually a single point where it really comes out sharp in the viewfinder and that's the point when I take the shot. Try focusing on the eyebrows when shooting people, or even better, on their iris if you have a good view of it. Basically, focus your eye in the viewfinder on one particular area and watch when that becomes sharper - continue focusing until it becomes unclear again and keep in mind that interval, then focus back and try to find the optimum point. An eyecup magnifier like the Pentax O-ME53 also helps a lot.

thanks i will get a focusing screen. Was it easy to install? Also I sometimes dont get the focus approval in the viewfinder. Is there a setting or something i may be missing? set to MF/AF etc.
With a small amount of patience it isn't that difficult to install. If you have large hands and fingers it may be a challenge, but the place I ordered mine from included finger cots (to keep oily fingers from fouling the screen) and a pair of tweezers to aid in the process. The install took a total of less than 10 minutes and if you're experienced with it I imagine you could do it in much, much less.

Here's one of my favorite recent shots that I got with the M/50 1.7:



I surprised her from the backseat and I really think the focusing screen helped me to find the right focus.

M 85mm F2

Most of the M 85mm F2 shots I have seen are portraits of people.
However, this lens is awesome for shooting animals as well.

No, my reply was to someone a few posts up who asked why he didn't always get confirmation. I should have quoted him, but when I started typing up my response, it was right above mine. I guess i got interrupted in the middle or something, because several people ended up posting between him and me. Sorry for the confusion.

Focus when the subject is still, then follow it while it moves. takes practicwe, but it's doable if the action isn't too erratic.

Took the old M 50 1.4 out this evening. It's hell getting old, i missed focus on a LOT of shots. But did manage a few decent ones. Shot most wide open.











I believe this one was at F11, or F8.

Beautifull semi abstract shots Stratman!
I have difficulties to focus the 50/1.4 too.
In the film days I had no focussing problem with the same lens.
Since I don't experience the problem with other lenses
its not my eyes but the lens I think.
Must keep on trying because of the nice boké.

Axl,

I'm intrigued by your last M 85/2 image with the bubbles. What is the story behind this one?

In my own experience, the faster the lens is the harder it is to focus wide open, especially when mounted on DLSR

A few more from yesterday...

Here are a few more taken at softball practice yesterday taken with M50mm1.7







The fly is at 100% crop.







maybe not as arty as the cityscapes, and still struggling with composition. One day it will all come together.

It's neither. See my comments a few posts back. It's the focus screen, which lies and shows too much DOF at large apertures. this fools you into thinking things are in focus that actually aren't. The focus screens on most film SLR's were designed differently and did not suffer that problem.

Here's the post where I discussed this:
