I agree, both are quite good. But what are they? What are the experiment conditions?

Thank you! Bookmarked

Me too!  :-)

I have photographed extensively - even regularly! - back lit scenes and subjects, because I like the resulting contrast and silhouettes. I have NEVER seen anything even remotely close to this ...

The EC-20 is a 2x Teleconverter for the Four-Thirds mount. The MC-20 is for Micro-Four-Thirds . Be aware that the MC-20, and the MC-14, only work with the 300 f4 and (I think) the 40-150 f2.8 - and ...

If you run with sufficient momentum than you may slow down the rotation of the Earth! That would mess up IBIS - among other things!  :-D :-D

Yes... But the MC teleconverters do NOT fit all existing extension tubes. They do not fit, for example, the Kenko extension tubes, one of the most widely used brands. According to information in ...

Very nice!

Others may disagree (and probably will!), bur I think you are asking a wrong question and trying to solve a non existing problem. The increase in quality, due to larger sensor size, of APS-C ...

Bill, I am convinced (by all I ever read) that in mirrorless cameras the only sensor, so to speak, is the sensor itself, for light-metering, focussing and image taking. My qualifications in ...

Frankly, I don't think so. It is true that I never use the upper limit ISO in my camera (Olympus OM-D cameras), but if I eventually happened to cross my path with the Pope in a dimly lit church, ...

Lesson: always RTFM!  :-)

There is (with my camera) a considerable amount of vignetting. I post to pictures taken just now, with the 20 f1.7, @1.7. The first one is just a straight raw conversion, no pp done to the image.. ...

I repeated with spot focussing, apertures 1.7 and 8.0. The center (area of the AF position and also the metering point) is about indistinguishable, but the outside is darker in the f1.7 case, due ...

I Tried just now with the EM-5 III and Lumix 20 1.7. I do notice a small variation, which I attribute to vignetting, because the centre of the image is always abut the same, though the overall is ...

Bookmarked it. To watch time and time again! Thank you!

Thank you very much! I am going to try. Meanwhile, keep up the good work!

Fantastic! Everything is good in your pictures: the overall image, the detail of the subject, the lighting (which is translated in a 3-dimensional quality of the subject), the background with a ...

Very well done!
