Originally posted by jolepp Yes (and no ). "Apply all" affects all lenses except those for which "Apply One" has been set . That is, all MF lenses would share the same setting (with those more modern lenses for which "Apply All" had been chosen). "Apply All" and "Apply One" are not cumulative, also with modern lenses the body can tell them apart as it gets a lens id through the data pin (whether the lens id is copy or type specific I don't know ). I suppose "Apply All" could be set to compensate for any misaligment of the AF vs. image sensor which would affect all lenses. If lenses the body can't tell apart would require a different setting that would need to be set through the menu when changing lenses
Gosh this is very confusing ... sorry Jolepp.
Originally posted by jdbosma It's a different approach to the issue, but, if your camera has LIve View mode and you can use it, then there is no need to worry about front/back focus, focus trim, etc. On the K-r, and I assume many other cameras, Live View lets you zoom the image so that very precise focusing is possible.
I have used this technique (on a tripod) in some situations where focus was critically important and have been quite pleased with the results. For me it is faster and more sure than trying to use the viewfinder.
Hope it's not off-topic. The OP indicated that "correct focusing" was more important than "shown in the viewfinder."
That is one good idea and I never thought about it.
I will try this out and see what focusing results I get with this method.
Originally posted by pentup Yes, but it's easy to work around. Which camera are you using? If you have the K-5, you could simply devote one (or more) of your five user modes to "apply all." In fact, you could have a different "apply all" setting in each user mode if you wanted. You could do the same with the K-7, but limited to one custom user mode.
Yes, I have the K5.
Your suggestion to use the "User Modes" would make a lot of sense so that all MF lenses would be "clumped" in one single group; but other members below mention that BF/FF doesn't exist for MF lenses ... ??
Do I make sense ... not sure?
So, what exactly should I do with this manual-focus 85/1.4 lens in order to get proper focus
results?
As I mentioned earlier, I am not so concerned about what would show through the viewfinder as much as what would show as a final image.
I will definitely test that focusing issue via the Live View method, but I'm not sure if I'd want to use this all the time with this particular lens. There are times that Live View would be OK to use, while most of the time it would be better to use the viewfinder.
Can anyone suggest some sort of detailed procedure to take, step by step?
Thank you all so very much for the time you take trying to explain this to me.
Cheers.
