Re: prime lens question?

Okay James and all, I think the penny has finally dropped.

28mm on any lens will always be 28mm. 28mm on a 35mm or full frame camera will have a slightly larger FOV than a cropped sensor like my K10.

The 28mm prime I use will be giving the same FOV as my kit lens at 28mm. The different apertures will play a part but the 28 remains the same. The same goes for my 50mm prime. That too will give the same view at 50 on my kit lens. The 1.7 on the prime will be brighter than the kit at 50mm that's all.
