This is where things start to get interesting. All the other lenses I've shown so far have been rangefinder lenses which could, theoretically cause problems on the new Alpha cameras, and probably will. SLR lenses on the other hand do not cause this colour cast problem and are the better choice of lenses. I have some excellent Nikon, Olympus, Pentax and a couple of other lenses from other manufacturers and they are very good. Because I prefer shooting with a rather longer focal length I have a few 75mm to 135mm lenses which I have high hopes for. These alpha cameras were purchased because of these old but excellent manual focus lenses. It's only a matter of practice before one becomes pretty proficient at using them with success.
