thnx. that guy was waiting for someone and i hid behind flower shop 20m away and shot portrait of him without him noticing me. i focused on him through the flower shop (which has glass walls) and just popped around the corner of flower shop and took several shots

also that cat i shot through the mesh of the fence, but this being a long tele you can't notice that on the photo,only bokeh in top left corner shows it

Stunning images as usual from you.
Well taken.
Is this the same lens as the Meyer Optik Gorlitz Telemegor f4 and/or f4.5 ?
OH

Nice set! That is sharp! and color rendering is also very nice!

One question: how do you find using M42 lens on M43 body? Does 2x crop factor bother you? Especially for 100mm+ lenses.

using them is just fine. it's wide angle lenses that are "problem", because they are not as wide as they originally are, but as i don't really shoot landscape (or rarely) it doesn't bother me as much

But then handheld with an equivalent 300-400mm lens will be hard to deliver sharp image or?

Normally yes, but not the case with EM-5. I found the 5-axis IBIS very effective, compensating up to 4 stops.
