|comment:||If you're looking for a wide angle lens for full frame then this is the lens to go for. Unbelievably wide and handles distortion so very very well. Fun walk around lens for metropolitan areas. The extra 5mm may not sound a lot moving from the KM17-35 but it makes a massive difference. It's not the sharpest lens, but to be honest it's pretty bloody good. If you're using it on FF you've got to be pixel peeping to see. |
It's also important to remember DoF is from the subject to the sensor; a lens like this needs to be put right up to the object you're taking so unless that object is concave, one part of that object will be very close to the sensor and the rest won't be. While it may still be soft in the corners, often this is due to the shallow DoF.
If you're on crop sensor (anything except A850 or A900) but *might* move FF in future I'd recommend getting this. Will be wide enough for most stuff and is then useable on FF (the tamron 10-24 is a good lens, but not compatible with FF).
Thoroughly recommend, but if you are going to get into wide angle stuff, do some research on how best to use them. This is the best article you can read, and you really should read it:
