I guess this question can be asked about any lens really. Sorry for posting so late.
I\'ll be going into a camera store tomorrow. It\'s over an hour away but the guys there know me and I have reserved the sigma. They will let me have a play with it and compare it with my canon 50mm f/1.4. I\'m also taking my laptop. The store is very small.
The only lenses I have used in the past couple of years are the 24-105L, 35L and 70-200L f/2.8 IS, on a 5D. The last 2 I have sold- and need a low light 50mm for the occasions the 24-105L is too slow. I have briefly used the canon 50mm and it\'s a bit hit and miss. I like how numerous times i have used the farthest AF point on my 5D and shot wide open and nailed the focus with the canon. On the other hand, the \'sticky\' focus and build is not good for me.
Want to go up to the Sigma because of the build quality (feel like I\'m gonna break the canon) and have fingers crossed that it\'s IQ is better too. Also I can sell the canon 50mm and for the same price i can buy this sigma. In effect, a swap.
I\'ve read pages and pages of pro\'s and con\'s about the siggy and want to ensure I get a good one.
Can you please tell me how I can within 5-10 mins test to see if this sigma is one of the good one\'s?
This is what I plan to do:
1. Take a couple of close up ( 50cm - 1 meter away) shots of a newspaper article with both lenses (at f/1.4 - f2/8) to check focus/sharpness. Repeat this for a medium distance (2-3 metres away)
2. Shoot a couple of shots outside to check focus/sharpness, CA and colour/contrast.
3. check the serial number and hopefull it is after 1016 XXXX
Hook up the camera to laptop and have a quick compare. Is that enough?
Never really tested a lens as my previous one\'s have been great. But all this talk about the sigma\'s \'issues\' got me worried.
