I've replaced my standard viewfinder screen in the K10D with a katzeye one and need to have it calibrated (shimmed).
I basically want to send the body with only one lens to the repair center for this.
What is the best lens for this calibration purpose?
31mm/1.8 (30cm)
55mm/1.8 (45 cm)
55mm/2.8 macro (25 cm)
85mm/1.8 (85 cm)
135mm/3.5 (150 cm)
200mm/4 (250 cm)
300mm/4 (550 cm)
Is it the lens that can give me the biggest projection of a subject at the minimum focusing distance? Or the lens with the shallowest DOF wide open? Are there other factors?
Or is it better to send the whole bunch?
PS first lens is the FA31Ltd, others are (M42) takumar flavors and a (M42) vivitar macro
