fuji 35 has beautiful bokeh. should be just fine for portraits.

You can always try and you may also succeed most of the time.

But just be aware, that with the 35mm on occasion you may have to get too close to your subject, and might start noticing unnatural perspective in ther subsequent images evidenced by big noses and fat lips.

To prevent this happening, you may have to stay further away, and crop the image later to restore the desired composition.

Try a few things and see how you like it.

Good luck.

When cropping, it will behave just like a crop sensor. If you have a f1.8 lens, it will be equivalent to a f2.9 lens when you crop the image.

What you are loosing is the max aperture and resolution.

Uh wut?

You're just losing resolution...

Do you think you would have the same results as a 56mm f1.8 ?? You are loosing more than the resolution, the photo will be noisier and will have deeper dof.

It is the same rules than with a crop sensor. f2.9 is the equivalent aperture (in terms of resulting image)

I like to shoot horizontal, then crop the sides to make a vertical portrait with this lens. You lose resolution but thats ok for portraits, still plenty left.

That's incorrect.

Aperture is a mathematical ratio specific to the lens it is calculated for. The aperture of a lens on a full frame sensor will be the same when the lens is mounted on an APS-C sensor.

What changes on a lens with a crop sensor is the field of view and the depth of field.

That depends on how much bokeh and surrounding background you want. Rent the lens and decide for yourself.

I am talking about equivalence, about resulting image if you want (this is what matters !)

Take a portrait with a 35mm lens at f1.8 and crop to have the fov of a 56mm. Take the same portrait with a 56mm f1.8 lens. And compare.

Dof will be shallower with the 56mm lens, it will be also less noisy... In fact, by cropping, the result will be "as if" you had shot with a 56mm f2.9 with less resolution.

Sometimes it is difficult to tell the truth in a forum :-). Even if I post pictures demonstrating the effects of crop, there will be always some people that will deny equivalence (a really misunderstood concept)

You'll likely see some distorted features if you take tight head shots but if you step back to include the whole person, or most of them, you should be good. Henri Cartier Bresson used this equivalent focal length for his work and those portraits turned out pretty good

I own both 35mm and 56mm primes.

I wouldn't crop images too much; you want to preserve as many of those 16MP as you can --- unless you are strictly going for low resolution applications such as the web or smaller prints.

As others have mentioned, the 56mm more easily gives you the ability to go for subject isolation using shallower DOF because you can achieve the effect easier by getting closer to your subject rather than trying to position your subject further away from the background.

Since you can shoot the 56mm further away from your subject than the 35mm, you do get the more pleasing telephoto compression effects without cropping.

There's also the fact that the 56/1.2 was optimized for portrait work (vs. say the 60mm macro), which may also help.

But, back to your original question:  if you don't do many portraits, then sure, using your 35mm works just fine.  Pose your subjects/select the backgrounds as required.  Working a little harder to get the sort of portraits you want using the 35mm can be more satisfying that just saying you can't really do portraits until you get a 56 or 60.

If you do lots of portraits, you've probably taken the 35mm as far as you can already and can justify the expense of the 56/1.2mm.

35mm is the lower bound to shoot portraits. It is possible to take nice portraits, cropping a bit may be a solution, the center of the photo is always sharper.. From my personal experience, I consider that I still have really good IQ until I crop x1.5. Until an equivalent 50mm in your case.This is just from experience, take it with a brain of salt. There is no general rule, it depends on the lens.

Physics says that the 56mm at F1.4 would have smaller DoF than the 35mm at F1.4, so the background blurs more. But then again, maybe not important, as the 35mm is a lovely lens anyway!

If I'm not wrong, cropping the 35 to have the FOV of the 56 is a x1.6 factor.

You will get a 10MPx picture. Not so long ago, we were not unhappy with a 10MPx sensor camera !

You don't have a lot of pixels to start cropping away. A 50mm equivalent is good for full frame portraits, especially of the type showing the person in their environment. No one will like the perspective distortion of a tight head shot.

I was in the car and took these with the 35.  They are cropped an average amount, probably 40 to 50 percent crops.  I think you will be fine standing back and framing loose and cropping in a bit, just don't go cropping beyond 50 percent.
