For half a year this has been my main glass on the a7m2. Portrait photography, landscape photography, street photography, travel - fifty dollars can do everything. But if fast autofocus is critical to you or you are very nervous, then the lens will not suit you. Has some pros Lightweight, fast, inexpensive fifty dollars for a full frame. Has some cons Autofocus. He has to endure. Slow, noisy, dull autofocus. About 20-30 percent of the time it's faster to work with manual focus in combination with focus peaking.
