Shortstack and sweet
This lens is very useful, especially if you like to do candid or street photography. Because it barely sticks out from the camera body, it's easy to use one handed, it makes an SLR feel light like a point and shoot but gives you the all the options of a DSLR. Very quick autofocus response time, and very sharp and easy to use in manual mode, even if you have big hands. The picture quality has been very good, the large aperture allows for low-light photos, and though it is not a true macro lens, the details come out very sharp shooting in close. The small lens doesn't allow for screw-on, there might be an aftermarket adapter.
Pros: Useful, large aperture at low light, responsive, light and compact.
Cons: No filters
