Re: Four Thirds lenses vs Micro Four Thirds lenses IQ

I haven't tried the 70-300 on bodies other than the EM1, but hang on and I'll see how it works on the GX7.

OK - I just got back from trying the 4/3 70-300 on my GX7. It eventually focused but hunted a great deal, and continued to hunt on its own without my finger on the shutter button. It was also quite noisy. Not recommended. Same on my Olympus EPL-5.

On my EM10 and EM5, things were quite a bit better. Still hunted a bit, but locked on focus relatively quickly. No additional hunting with my finger off of the shutter button like like it did on the GX7 and EPL-5. Te lens could be used on these two cameras, but was far faster on my EM1. Still noisy on the EM10 and EM5, but slower (not bad) AF..

My thoughts - 4/3 is a very good lens on the EM1, could be used on the EM10 and/or the EM5, but slower to focus. Don't bother with it on the GX7 or the EPL-5.

So - EM1=good, EM10 and EM5=Fair to midlin', GX7 and EPL-5 (or equivalent)= No go, use the Oly 75-300 or the Panasonic 100-300 (Note: Has lens stabilization) on those. I have a G5, but didn't try that. If you are going to use the 70-300, best to do so on a newer Olympus body with internal body image stabilization.

I hope that helps. Note: On EM1, worked great, AF faster than on my old EVOLT 510,

Peace. ...and Best Wishes.

John
