Hi everyone, please help me out! I am on a very tight budget and I need a lense with a decent range. I saw this listed as an F2.8 -4 which will help me for low light situations, but I am wondering about optical quality, build, etc....It is listed on B&H for $209 USD, and seems very reasonable. I want to capture some decent quality shots that I could potentially use for sales, but I cannot find any reviews on this lense. When i google it, it only brings up press releases anouncing the launch of this lens.
I also saw a Sigma 24-135mm F2.8-F4.5 listed for $339 USD that I am considering, but I am not sure if it is any better.
Has anyone used either of these lenses?
