KP with Beroflex 500mm f8 and 1.7x AF converter


Philzucker posted a thread about his Beroflex lens and I wrote to him that I will try out mine.

Via using the KP and the 1.7x AF converter I made out of my 500mm a 1275mm lens.

Ok, that is not a must do, because I reached the IQ limit for my eyes. Maybe a print size of 10x15 or 20x30 (I hope ) will be ok.

I used this combination for to have the birds in the tree very big in my view-finder, so that I could better manual focus.

It did makes fun to try it out, but of cause, this is not a really good combination, because the cropping factor is too big for the IQ of the lens.

My best result is this picture from a common chaffinch (@ f16)

It's the original frame (no cropping)

best regards KPM2
