Originally posted by mixen usually take photos of clothes in model in indoor. This lens is ok but I need more past and sharp picture.
I am looking for an appropriate lens for this purpose in reasonable price.
I'd say either the Pentax DA12-24 F4 or DA17-70 F4, i say the zoom and F4 because most likely you'll be shooting at 5.6? and wide open at F4 you'll have just enough to get everything in focus, the zoom factor should cover you from shooting in tight spaces as some design studios are fairly cramped.
If those lenses are too expensive as you noted "budget", see if you can get a 16-45 F4 ED or 40 2.8.
