85mm vs 100mm on FF

I really don't know which focal length to pick for portrait photography esp., in concerts, party halls and marriages.

I am very keen in shooting concerts...

The difference is pretty small...

Better to compare on a lens by lens basis

Or better yet get a 70-200 f/2.8L II IS as long as it is fast enough

Do you have a telephoto zoom that covers both? Check the differences yourself and see if it makes a difference. For me, I don't find that there's that much of a difference between the two focal lengths. I think that, in your position, it would come down to comparing specific lenses as opposed to the two focal lengths.

I shoot mostly film and I prefer EF primes for that matter. Grains on print esp., in low-lights is amazing.

I think, I will go with 100mm and fast film.

Other factors such as sharpness, does not play a bit role with low-light photography. Since, you need to bump the ISO or usage fast-films results in noise or grains. Grains are kind of cool...

I only think about the shutter speed. I will be very happy if I get 1/60 or above.

Which maximum f-stop 85mm and 100mm are you thinking of buying?

If it is canon then EF 85mm F1.8 or EF 100mm F2.0. I discovered sharpness play a least role in low-light black-and-white photography.

EF 85mm F1.2 is too expensive for me.

I have both analog(Euro 35) and digital SLRs from Canan and both takes EF lenses.

Either are fine. It largely depends on your other focal length....at least it does to me. I've got lenses from 21-70, so 85 is a bit close for me.

Either are fine lenses and very similar.

Almost my head explodes with curiosity, how the prints will look like when shot with high-speed film.

Here I attach one with EF 50mm F1.4 shot with film speed ISO 3200.
