About this photography tip:
I am sure many of us have purchased lens before and been told that we should have purchased something different. I am also sure many of us have purchased at least one or two and then released we actually should have purchased something else. All in all each lens performs differently when paired up with different camera makes and models, even more the sensors inside those bodies. APS-C  cameras while they are the most widely produced due to their lower cost, tend to also be the hardest on lens, however the smaller sensor also means the glass in the lens can tend to be smaller and that can be a real cost savings. In this photo tip I wanted to talk about ways to compare lens and cameras using a non-biased method called DXO Mark. DXO Mark is essentially a benchmark to see how well your camera or camera lens performs. This is very useful for lens like my Sigma 17-70mm Contemporary lens that actually made for a wide range of camera makes like Sony, Nikon, Sigma, Canon and so on. This can help you get a better idea of how well your lens performs on your camera before you run off to buy it. Currently DP Review normally only list Canon and Nikon cameras for most of their test, this is actually fine as many of the Nikon models use Sony sensors as well as most other camera manufactures with the exception of Canon. So if someone tells you your next lens if garbage and you can not figure out why, hop on over to here and check it out. It may actually just be the other persons lens/camera combo they are using.
