I'm having a bit of dilemma choosing between the Sigma 30mm F1.4 and Tamron 17-50mm F2.8. Wonder if you guys can give me a little input.
My current set up consists of Canon 40D (crop), 18-55mm Kit, and 135mm F2 L, with a flash.
For leisure i pretty much shoot candids with my 135mm F2 L all the time, recently sold a 50mm F1.4 because i rarely used that range.
What I'm looking for now is a decent, yet budget replacement for my standard range, almost just to cover range, but of course I'm sure a standard lens will come in use for me.
I generally shoot people most of the time, occasionally cover simple events.
Actually I've kind of narrowed down my concerns too, i'll list them below:
Image quality - I believe they're somewhat comparable, but really I've read/heard many mixed opinions and reviews. Any users care to comment?
Tamron 17-50mm F2.8,
+ Advantage of Zoom
- Noisy focusing? Micromotor AF...
- Focusing inaccuracies issues... I actually owned a bad copy previously before.
- Dust issues? I know it doesn't affect much but it can be disappointing
Sigma 30mm F1.4
+ HSM focusing (is it good? I've heard mixed opinions too)
- Lack of zoom
- Slight uncertainty of 30mm is a good range, leaving foot zoom to do the rest.
- If IQ below F2 is unusable, my decision will sway almost immediately.
That's what I think at the moment. Love to hear what you guys think.
In fact the very main question might be, is the 30mm alone good enough to cover simple private events (ie. birthday parties, small weddings)?
Thanks in advance!
