Mate, as I said, I used the XCD90 for everything, as it was the only lens I had.
I was able to do a full length on a short model but only just. A 65 would have been handy.
However head and shoulder shots I had to crop in. A longer lens would be better.
I suggest that you use a Canon or similar zoom with an adaptor and just read off what you need.
Camera stuff is too expensive to keep on buying.
(Modified) - I am just going to summarise in case there is confusion.
For nearly all of the shots I took the 90 was fine, in fact it was too short and I had to crop the images in post.
For a couple of images a shorter lens (45, 65, a zoom, maybe 80) would have been useful.
You make do with what you have.
