OK here it is:
Kilfitt 90/3.5 Macro.
note two focus rings...
Canon LTM RF 85/1.8 on the kilfitt focus tube.
grabbed my LTM RF 50/1.2
and screwed it on there-- I was loking for the bokeh
I was pretty excited, so all shots you see are handheld
these are not crops, how close was I? Here is a gross but effective way to show (my thumb)
again no crop, but smaller so nobody throws up.
How about the 85 shown above?
all these are teeny flowers, but how close?
I was shooting HANDHELD wide open at about 400 iso to get a fast shutter speed. I think it's pretty obvious some very respectable captures could be made with a tripod and really good focus.
anyway revelation to me
what about the little kilar 90/3.5?
