There are too many lens choices of the same focal length in the market. What are your considerations and which are your most important criteria? Here are some picks for you:
1) Sharpest among all
2) Lowest CA among all
3) Weigh below a certain limit
4) I have a Budget
5) I only buy lens f/2.8 and bigger
6) Vignette to the minimum
7) I follow reviewer’s recommendation
8) I swear by DXO marks
9) I have to see photos taken with the lens to decide
10) I have to feel and play around with it first
11) Only lens by Canon
12) Image Stabilizer is an important factor
13) Fast, accurate and consistent AF
14) Corner sharpness
15) Flare control
16) I care about the material and feel of the lens
17) Others
For me, I always consider the weight first, followed by Budget. I do read reviews for reference (my favourite is photozone.de) and if I cannot make up my mind, I will rent to test out the lens. I am 3, 4, 10 and 11. If the lens has IS and not crazy price, it might become my favourite pick.
What’s yours?
