Re: Help me find out what I'm doing wrong or if my TC14 is defect?

I also have issues with my 300 f/4, with and without the MC-14. I also have a filter on mine. I've tried it with and without the filter, zero noticeable difference. I also put a large scratch on the front element of my 40-150 f2.8 before I had a filter on it. I used the hood and lens cap religiously,

i use electronic shutter all the time with the 300 and E-M 1.2 It helps, but there are times when I just can't obtain focus with the 300. I can even swap the body to an E-M 10.1 and I have the same problem.

I also have almost zero focus issues with the 40-150 f/2.8.

When I use my 300 with or without the TC, I have zero issues until I get past 100 to 150 feet, then it's any bodies guess. Lighting conditions are mostly irrelevant, but lower ISO is usually better.

i also talked to Olympus support and I got zero help.
