And by focal length, I mean normal 35mm focal length that all lenses are measured with.
The Lomography web site is total out to lunch, below info from their site on the 35mm lens
The Diana F+ 38mm Super Wide Lense on a 35 mm is equivalent to a 72mm standard lens. Used on a APS-C sensor DSLR it has the effect of a 115mm tele lens!
Roughly equivalent to a 25mm lens on a standard 35mm camera (a yielding a 120° view angle), this classic super-wide perspective is a favorite of street photographers and photojournalists the world over. Images scream with detail; the distinct Diana look of vignetting and dreaminess.
I think the Second area is correct, therefor the Lens is actual app a 35mm lens on FX and app equivalent to 52mm on DX
Please Niko/Admin or others that have these lenses, what is the app actual mm focal lengths. Also which 2 lenses should I get, one of my suppliers have them in stock now
