Return to original shooting style

In order to return to origin of photo shooting for full manually shooting, I made up my mind to do that on Canon 7D. not only zoom lens but also 3 fixed focal length lenses are going to be invited. Full flame size lenses need some modification if they were on APS-C image format. Of course angular perception must be changed into 2/3 leading to hood depth specification changes. Tele-Elmar M 135 mm/f4.0 mounted in Minolta MC Tele-Rokkor 135 mm/f3.5 had some modification on hood depth that is equivalent with 200mm on APS-C format. Minolta MC Rokkor 58 mm/f1.4 for 85 mm equivalent and Minolta MD Rokkor 35 mm/ f2.8 for 52 mm had the same operations on the sunshade promptly. The modified lens hoods look the same as lens barrel length, extraordinary long hoods they are. Hood depth should be as long as possible under the requirement that the lens barrel set in infinity position and the iris should be the most closed condition. It goes without reporting that the internal surfaces of them are all plated with non-reflective black cloth, indispensable countermeasure for avoiding the intrusion of reflective light noise.
