In preparation for my upgrade to a 5d3 (from a 60D) later this year I'm trying to compile a list of potential prime lenses to get between the 35 and 100mm range. I've already got a 24-105L and will sell my non-L 70-300 to get the L version. Also have a 50mm 1.8 so I'll need to get a 85 1.8 to get my portrait capability back.
Then the question remains: Do I keep the little plastic toy (which never use wider than 2.8 anyways) or just get a pancake (which is actually pretty usable wide open, vignetting aside)? Do I even need a 50? I know the 50mm 1.4 isn't great wide open either and has fragility issues but at least it'll work with the automatic CA corrections in the 5d3 (I shoot RAW+jpeg). The sigma 50 1.4 is...really big for a 50mm prime, has AF quality control issues and won't work with auto CA corrections. Rumor mill has it that the sigma 50 is due for a rebody to the "art" line they've got going now but probably won't get an optics refresh... Oh yeah, the 50mm 1.2 is a no thanks I'll keep the money. Everything 50mm seems to be a compromise and you'd think after so many decades of people using such a prolific "normal" lens the designers would have perfected the formulas by now.
Do I even need a 50?
I have the 50 1.8 ...ok in a pinch I suppose...
but.....NO ....skip the 50mm.....I never found one that I liked
get the sigma 35 f1.4 ...
this is a VERY good 'normal' lens..
it is just GREAT wide open
sharper than most other lenses ...wide open
clean...from most aberrations..
I just went for a walk with what I think is essential......
an ultrawide 14L II (or choose a 16-35 II)
a sigma 35 1.4....really good value and sharp...and it pops the shots....
and a 100mmL macro (or choose the 135 f2)
add a 12mm tube and a 1.4x TC (a tamron fits the macro or the 135L) - especially with the 135L ,
and insert your .... 5D3
love it all
I have the 24-105 (nice lens) if I only want ONE lens.... it never fails to please....24mm is pretty wide already
and....I also have a few specialty lenses ...85L II, 70-200 f4 I.S., 70-200 f2.8 II.... 24L (mk 1)
but the three basic lenses (100L versus 135L ...you decide)
are enough to do the typical stuff...
