Switch to full frame with prime lenses?

I'm thinking of buying a full frame camera. I know the advantages I will probably see by doing so. My question is for those that switch to full frame using prime lenses, did you have to sell your primes that you were used to when you switched and buy different ones? I like the 35mm and 85mm on my crop. Will I want a 50mm and 135mm when I buy a full frame camera?

Surely it all depends on what you want to shoot?

As Nellyle says, it depends on what you shoot, but it's not unreasonable to expect that your most used prime focal lengths will change. I used a 28mm f/1.8 and 85mm f/1.8 when I shot a crop body, and then added a 50L and 135L when I went full frame. I kept the 28mm and 85mm for over a year to see if I would still use them. I almost never did, so ended up selling both lenses.

Portraits of my family is what I shoot.

If you want the same field of view, then adding those might be a good idea.

Heya,

I shoot both full frame & APS-C. I use the same primes on both. Doesn't matter which you use, it just changes your physical distance to them for the same field of view. Minor difference in depth of field due to that. No other real advantage, if doing portrait, if you're not seeking the thinnest depth of field possible.

Here's Full Frame & APS-C, 85mm each, F2, F1.8, F1.4 to give you an idea of how different the depth of field is. Since again, the only real difference is physical distance to subject based on field of view and composition:

Guess which is which before looking at EXIF.

You'll likely be disappointed by the canon 50 f/1.4 coming from a 35 F2 IS. Though you'll likely enjoy the 135 f/2 over the 85 1.8. I'd hold onto your current lenses and see how you like them the FF before you go about selling and changing. You might be pleasantly surprised from the focal length changes.

For me, yes. I loved my 35mm on crop, could never get used to it on FF though. 85mm is useful on both though for me.

That was the tactic I took. In my case, I found I didn't need the old primes, but I feel better knowing I gave them an honest try. In the OP's case, he may discover a new perspective that he likes. You never know until you try.

I went from a T2i to a 6D and find that while the focal length is different, the lenses are still excellent lenses so the images are just as excellent as before although the focal length may or may not suit your needs.

I actually went to a 7D before the 6D and kept the 7D. The comparison between the two cameras with the same lens is simply focal length. I have three primes and enjoy each one of them.

The major difference is the image produced by the different sensor. You say you know the differences so I won't go into that, but you will DEFINITELY enjoy them.
