I know it's probably somewhere on the forum but I can't seem to find the answer if I want to purchase a 50mm lens for my Pentax Kr what is the nearest 35mm camera lens to this

Are you saying you want the same angle of view/magnification?

If so the multiplier is 1.53 / 1.54 (ish).

So, 50/1.54 = 33

The nearest would be a 35mm lens.

If you want an equivalent field of view to a 50mm lens on film, on a Pentax DSLR you will need a lens of between 30 and 35mm. The DAL 35mm f/2.4, DA limited 35mm f/2.8 and FA limited 31mm f/1.8 are the best options from the current line-up.

Many Sigma lenses also fit Pentax cameras. The 30/1.4 or the new 35/1.4 are excellent choices too

And there's a lot of old manual focus K glass out there, certainly 28mm f/2.8s (my favourite 'walk-round' prime on APS-C), fewer 35mm's though for some reason. Not quite as convenient as AF lenses, but cheaper.
