I bought the Schneider Componon-S 100/5.6 enlarger lens quite a while ago sitting in the dry cabinet. After trying the SL66 120/5.6-bellow set up I find it too heavy and suddenly thought of this enlarger lens set up. The 100/5.6 can be used with the Rollei bellow very conveniently and is a very light weight macro set up for very close up photography.
Of course I have my very high quality macro lenses like the 60/2.8 Makro Planar and the 100/2.8 Makro Planar. But from specification point of view the SL66 120/5.6 MTF shows better lens performance for magnification larger than 1:5. So I think it will be the same for the Componon-S. The 100/5.6 comes with a lever to open or close the aperture, and also to set the aperture either in steps adjustment or smooth adjustment. The lens comes in M39 screw mount, so to use on the Sony Alpha 7 it will need a M39-M42 adaptor and a M42-FE adaptor. In this case I am using a Rollei QBM bellow and thus a M42-QBM and QBM-FE adaptor. The bellow will allows very easy framing and focusing of the lens as the 100/5.6 does not come with a focusing helicoil.
I managed to toke some photos outdoor and is quite happy with the results.
