Question RE: extension tube 10 for Hasselblad

[k.e._carter]

I have an opportunity to purchase a used Extension Tube 10 to be used

with my Hasselblad 501 CM and 80 mm Planar. Could this tube be used

for a tight head and shoulders portrait with the 80 planar? I own

extension tube 21, but it only allows for focusing much closer than

head and shoulders and is more suitable for macro work only. Would

extension tube 8 be a better choice? Thanks much for your advice.

I used the extention tube 10 (I think) with an 80mm to take some photos

of strawberries and I shot a head shot of my wife for fun. I think

using an extention tube for head shot brings you to close to work and

you don't get a lot of depth of feild.

good luck

Divide focal lenght by length of the extension tube and multiply the result by 54 mm to obtain the object size which fits on your negative. In your case 80/10=8 8x54 mm=432 mm (396-432 mm). With the 8 mm tube this would be 540 mm (485-540 mm).
