Default Camera lens as Enlarger lens

If one reads early literature particularly Leica information it recommends using the camera lens that one has taken the picture with as the lens to use on the enlarger. Personally, I don't hold with this on two counts. Firstly an enlarger lens needs to be very flat field and secondly adhesives used in the manufacture of camera lenses may be effected from any heat given off by the enlarger lamp. I do hold with the theory that certain focal length enlarger lenses are suitable for specific film format which 50mm is the ideal for 35mm albeit Leitz produce, as standard a 40mm for thier Focomat V35 which mens that baseboard to optics distance is less on equivalent size images compared with a 50mm

I doubt that there will be a problem with overheating since any heat reaching the lens has already passed through your negative, if that can stand it, then so can your lens.

They were wrong!

Your enlarger is a macro camera making a one to many magnification in a short distance. Your camera lens is not a macro lens and is making a 1 to 1/nth magnification over a very long distance. Very different lens design is required to optimise the two of them.
