VIVITAR 100MM F2.8 AUTOTELEPHOTO - M42

[Torchwood]

It's not mine, I have one and its a beautiful lens, good price too. Would need a bit more IR because of 2.8 aperture. Around 8x mag.

Edit. I thought it's buy now, sorry it's auction.

what kind of distance will you get with it using a T20 with a doubler on it

[Torchwood]

100yards is fine, eyeshine around 150yards.

I get clear image with a Sunnranger over 150 yards. more IR, more range.

i might have a go at it and try my T74 with it if i am lucky but it will add a good bit of weight will have a think about it
