Panasonic 35-100 f2.8 over Olympus 40-150 f2.8?

I find the 35-100 sharp enough at 100 f2.8. I bought into this system primarily because of the size and IQ compromises and in this regard I believe Panny is doing a better job of meeting my needs in the 2.8 zoom lens category.

Is this image super sharp, no, but he was coming at me at 40mph and it is sharp enough for my hobbyist needs. I'd just go to FF if size and weight weren't a major part of my kit choice. I am thrilled we have these two great options though.

Dear Mark,

Nice photo.

I used to take amateur yachting photos, with an E-1 and a 50-200 (not the SWD version). I have not tried the 50-200 yet on an EM-1 properly setup (I bought my son EM-1 so I can now try it properly, I have had an EM-5 since they first came out).

My post though, is about your sharpness. With the old E-1, in very bright Australian light on the waves, I was taught by the internet by a very helpful Pro yachting photographer who posted from  Sweden, to shoot the boats at ISO 400. Even with the somewhat suspect ISO 400 of the beautiful Kodak CCD 5 MP sensor.

My 50-200 still works, because I used to wash the lens and camera down under a tap after each session. When I told Canikon people I did that 14 years ago, I got abused as being a lying nutcase. The only issue with that gear, is there is now a bit of corrosion around the flash attachment point. Salt water can be dangerous stuff.

I reckon your bike photo would be sharper if shot at ISO 400, or an even higher ISO level.

Cheers
