Owner reviews: Tokina RMC 28 mm f/ 2.8
28 mm on FF is really wide. Good option for landscape photography, because sony focusing is sometimes really frustrating especialy if you want to focus to infinity. Also good for astrophotography.
This is really old lens. There is a few lensflare which I really hate at astrophotography. Be careful and protect your lens against parasitic lights.
This lens is really small light and cheap. For APSC something arround 35mm so for me good option for street photography.
