In addition to my film bodies that include AE-1, 5 and my digital bodied 10d and 50d I have a film 50E, the eye control feature is/was brilliant a definite backward step to not have it in the digital setup.
The viewfinder is a little darker than on the 5 btut much better than on any of the digital bodies. I prefer the 'feel' of the 5 but the 50E is technically more advanced, especially in the 'flash' area.
Now if only they could have made a 50E digital for a reasonable price
I assume the £16 didnt include the L lens??
Hope you get some good results, you'll be after a scanner next and some Kodachrome, or go B&W and start developing your own, therein lies a slippery slope towards your own darkroom.
