Are Canon 50/1.4 II and Canon 85/1.4 of the same sharpness, and is any of the 2 better for portraits ? Crop factor is about 1.4.

Thx.

Canon do make a 50mm f1.4, but the II designation is confusing. Are you referring to their f1.8 II instead?

Canon don't make an 80mm f1.4. They make an 80mm f1.8 and an 80mm f1.2L (which is very expensive but probably one of the very best lenses made by anyone ever).

You can compare the performance of the lenses over at:

and http://www.slrgear.com

Crop factor is about 1.4? How come - are you testing out a super-secret new Canon camera?

The XXXD and XXD range have a 1.6 crop.
The 1D range has a 1.33 crop and the 1Ds range and 5D have a 1.0 (none) crop.

Thx for correcting me.

You are right about the 1.8 II, no 1.4 II out there, and crop factor indeed 1.6 and not 1.4. And the Canon 85mm 1.4 that I was talking about is actually a Canon 85 mm 1.8...

Guess I should go on holiday.

Anyway, in real life, do you think the 85/1.8 is more adapted to portraits than the 50/1.4 ? Important detail : I hate to be "in the face" of the model, I believe in a better distance so that I can get more natural expressions. That is why I am wondering about the 85/1.8

On a 35mm Film camera, 85mm lenses were the lenses of choice for portraits because you could get far enough away for the photo to have good perspective and depth of field.

On a 1.6 crop factor dSLR, the 50mm lens has the same field of view as an 80mm lens on a 35mm film camera, and so will likely do what you want.

Also, what type of shots are you wanting to take?

Head shots?

Full body?

And how far away do you really want to be? With a 50mm lens to do head shots you'll be about 5 feet away. Full body about 10-12 feet away.

I have the 85/1.8 and it's a wonderful lens. However, with the crop factor, it really is a little too telephoto for portrait shots in my taste. I unfortunately don't use it much anymore.

And I am not very fond of tight crop portraits. So on my 5D I use 35-50mm for portraits.

Mostly my 50mm f1.4.

On my 20D I used to use the 28mm f1.8.

No right answer or best lens, just what you like to shoot.
