I know that there are two types of such lens a longer and a shorter version. What projectors have the short version (it can also be diaplan)?

Looks fantastic! What projector can it be found in?

I have long version. I removed it from an Aspectar 150 projector (thanks for the advice of another topic on this forum).
I want the short version now, but I do not know what projector to look.

I have the 2.8/100 Diaplan. How did you go about adapting it?

Good. I'm still using the antique NEX-5N. Assuming mine is the same register, I'll probably dedicate an adapter by doing much the same approach, but wondering exactly what adapter and helicoid. I wouldn't mind having close up ability, but want to make sure I reach infinity or near, even though it will never be used at infinity.

I used my feet to focus, so hitting it precisely was challenging, although when I did it seemed quite sharp.

I just bought this one and when I use the saw to cut down the extra plastic part, I accident scratch the back of the lens really bad. How do I remove the scratch? Please, help.

Thank you.

You don't, you replace the lens.

Sorry to hear you damaged the lens, it's now only useful for parts, please be careful when modding lenses, especially rare lenses, I would prefer the rare lenses not be modded, but you can mod the camera or adapter to your heart's content.

Almost forgot, Lovely shots kryss.

Thanks James.....

No prob.
It looks like the lens has some gunk on it based on the bokeh balls.

That's a very nice use of flare.
