Hi guys and thanks so much for the great responses.
I forgot to mention that I have a M50 1.4. the wife has a smc50 1.4 and I also have a m135 3.5 and a sigma 17-70 2.8-4.5 which is very sharp at f8 but a bit too soft wide open
as far as the 135 goes, is it wise to also have the 135 2.8? will one stop make that much difference?
I also saw a m50 1.2 but not sure of the price.
btw, what is an MIR?
juniper?
helos?
how old/expensive are the tamron 35-80 2.8?
as far as wanting it to be sharp, I love low light photography as well as portraits. low f stop will also do well with indoor volleyball.
I think it is a better choice to soften a bit in photoshop then sharpening
cheers
