Samyang 85mm t1.5 As if

[rugged glen]

I found this lens for ~$150, I want to understand how good it is for astrophotography, what aberrations and coma it has. and can it be compared with the samyang 135mm without taking into account the focal length

[nimble olive]

Samyangs have pretty bad QC so they are hit or miss. If you get a good copy you can basically get 0 abberations at f2 but if you get a bad copy you will have to step down to f2.8 or even 4 for an acceptable amount of aberrations

the 85mm is way more shit

than the 135

Samyang 135mm costs 2 times more and I can’t find it for the required mount

[serene scaffold]

yeah i get it bro

but the optics are way more shit on the 85

you can get it if u want but it's not nearly as good as the 135

Not any lens gho, i remember some brands not being usable on canon, check the adaptability before buying anything

You can change out the adapter
