i don't have more photos of the equipment but can go check out a 5D from school today and take some high res. shots of whatever you like - and as far as condition is concerned, my pictures have been coming out just fine, IMHO, the 50 was not working when i bought it, the schools printing tech. had previously owned a PRESS kit from Mamiya and said the price alone of a working 50mm would warrant owning the kit, he recommended i get it fixed and sell it to pay for the kit.
let me know what you would like pictures of - I can get that digital and i have a flash light if you would like pictures of the lens elements. unfortunately i cant get the shutter to work on the 50 so that one wouldnt be doable.
thanks for the interest.
