Steinheil Munchen Tele Quinar D 135/2,8

Petri Kuribayashi cc 50/2 & Lens turbo

The lens was in Petri bayonet, then modified to M42.
I use it on my Sony Nex 5 and Zong Yi lens turbo 1rst gen.
No degradation in term of sharpnes at center with this combo.

Carl Zeiss Ultron 50/1,8

All with NEX5

PZO Amar 105/4,5

It's been long time since I bought last enlarger lens. I got very tempting offer. I couldn't resist.
So here it is PZO Amar P105/4,5 with scratch on front coating.
All shots with Sony NEX5+Lens turbo, the combo is great, even on edges.
All wide open except the infinity shot at f8

Fujinon T 100/2,8 EBC

I got the lens in ugly body condition, rubber grip is gone, replaced by leather grip, and repainted.
The important for me, optic is not bad,  it has hair scratches cleaning mark only.
Tested in NEX+ Lens turbo.
wide open is impressive, all at f2,8

One thing  bother me, the closest distance is 1,2 meter, not close enough to playing dof. But we can add helicoid adapter or extension tube for that.

Pentacon 30/3,5 M42

Successor of Meyer Lydith 30/3,5 which I believe improved. specially in Coating. Lydith often prone to lack of contrast and flare too much. Sharpness and bokeh is same.
