Re: Long focus singlet lenses-Surplus Shed

you will need to stop down aperture
quality across surface not that good
I have 150mm by 4000

cut to 100mm then its ok

I wound up grinding a few of my own
hence "highfnum" I have 24 and 48 feet 125mm lens

what do you mean by real?
it does increase contrast

note standard quark has .6x reducer on nose

note standard quark is prominence model
note combo quark is chromosphere model
