That does seem a good price , I should imagine it will be an almost new camera too as it was the last model made at that level .
Enjoy it .
40mm and 50mm seem quite a close match for the first two lenses though , the field of view between them is just a step or two forwards or backwards .
Would you not be better with something wider or longer to go with your standard lens ?
Maybe a 28mm with the 40mm or 35mm with the 50mm . Or the 85mm f/1.8 with either ?
Just a thought .
