I have been Canon user for 20 years and when I started working with microstock photos I was on my second digital camera Canon EOS 20D. Now I am shooting with Olympus OM-D E-M1. I tried submitting images from point & shoot cameras, smartphones and even some old stuff scanned from slides (which probably are not included in this analysis cause I did not fill EXIF data).
Now I switched to different system and I am trying to figure out which lens I would need/like to have. Micro four thirds lens are usually half weight and half price comparing to Canon equivalents so I most likely end up with better ones. I read a lot of good reviews about Olympus 12-40mm F/2.8 PRO lens so it was my first choice when I was buying OM-D EM-1. Is it as good as Canon's EF 24-70mm f/2.8L time will show but for start it is half of the price :-)
Now let's bring subject of low light performance. I switched from full frame 5d mark II to half size sensor. I was wondering if this would have affect on noise of my photos and in result higher probability of rejections? Let's look at the data, do I need to have camera that produces low noise images at ISO 3200?
Going back to lens, which one do I need? It seems that 24-105mm was very convenient for me. From the data I have I cannot really tell if I got any favorite focal length.
Besides the fact that I am often going to extremes on my zoom lens other data is scattered all over the place. I was not using my tele zoom lens to often too.
When I looked at aperture data it seems like I am staying between 4 and 11 most of the time but I guess that two of my main lens were F/4 so I could not go wider.
