looks nice... and the hood is quite long! Shocked


The Sonia brand hoods usually are but then thats exactly what you need to shade a lens with a huge front element like this. The Sonia hoods have a male thread on one end and a female on the other so you can screw filters etc onto the front of them...And they dont cost much either. Wink

I also own a Spiratone 135mm f/1.8, which was built by Sigma.

However, I thought some of you might find this other lens interesting.

I was looking for a lens on eBay when I came across this 135mm f/1.8 attached to a "broken" night vision device. It was poorly listed, blurry photo, and I bought the whole kit for $60. I intended to harvest the lens and use it on my DSLR.

When I got the night vision device, I discovered there was a dead internal battery with a bad contact. I fixed this and now the $2500 night vision works perfectly.

The lens appears to be a Japanese made T-mount lens but the T-mount was changed for some custom mount that seems to be strongly attached with hex screws (and maybe even superglued in place!). I didn't want to destroy the mount by accident, so I left it in place.

The night vision is astonishing. It is a Gen III and gives remarkable images. It even came with a Nikon mount for the back of the imager.

(Sorry for the dusty photos)





Can anyone ID the lens maker?

today it arrived.

close to mint condition, perfect glass, smooth focus, perfect working aperture. only the M-A-shift is a bit sticky.

and it is HUGE! i will post some test pictures once i have my 5D (hopefully soon, i will find a good cheap one).



and attached to my EOS30


the design (here esp. the M-A shift, the lens cap, and the lettering) is very similar to the "weltblick 2.5/24" i sold some weeks ago. seems that it was the same manufacturer. does anyone have a clue which one it could be?
