panaleica 25mm f1.4 asph focus problem
4 months ago

Does anyone have experience focus problem in using e30 with panaleica 25mm f1.4 asph?

I used it for around two weeks and can't resolve the front focus even I adjusted the auto focus to +4 and sometimes the object is not correctly focus.

When I shoot an object with distance more than 5 meters, the result is back focus.

I really need some advice to handle the lens.

thanks in advance.

I bought a Panaleica last year and ended up returning it as I couldn't get it to focus accurately on an E-30 or an E-5.

This is the thread I started on it at the time. There's lots of discussion of the issue there.

That lens is best used with contrast AF which on a DSLR means live view.  I'd be interested to hear how it does on an EM1.

I had trouble with it on the E3
In reply to jbas78, 4 months ago

OOF shots, not necessarily always front or always back focus, but definitely was off focus.

After some trial and error, I found that the PL25 was locking onto things I couldn't see, like a stray strand of hair. The shallow DOF tends to magnify focus errors.

Solution was to set the E3 AF to center point only, focus target small. That eliminated, for the most part, the focus errors.

Haven't really had any issues with the PL25 on the EM1 - AF's quickly, and accurately. The PL25 also AF'd quite nicely on the EM5 as well.

I tried that just the way you advised but none of that worked. the panaleica will focus tack sharp when I add a fill in flash when using my e-30. if anyone have another method, please let me know.

thanks in advance

I switch do Diamond pattern in low light with the E5& the 25mm Panny & this does help a lot but I agree the 25mm 1.4 is the most unreliable of all my four thirds lenses.It does work much more reliably on the Panasonic L1 though.Still love it despite the frustrations in certain conditions.

What is "Diamond pattern"? Does the feature exist in e-30?

have you sent the lens to panasonic to recalibrate it? and is it possible to do that?

thanks

Hi, You're absolutely right. in e-30 the "Diamond Pattern" thing is called a Dynamic single target AF focus mode.

and for everyone contribute to this forum, please give it a try.

thank you very much

Your welcome,I didnt send the lens to Panny for calibration,They just work correctly without tweaking on the old 3 point focusing system on the E1 & Panny L1.Hardest thing is to remember to switch to diamond pattern on the later models in Low light.I have many slightly out of focus shots when I forget to do this,cheers.

from my short experienced using diamond pattern, in low light the camera using the other 4 AF point (assist point) to achieve focus and not from the center AF point so it is not the best way to use it .

if anyone have experienced using single target AF mode, please let me know.

thanks in advance
