how to visually tell the difference between RB lenses

[andrew_littleford]

Hello all. I am new to the world of Mamiya RB67s and have found this forum to be invaluable in my steep

learning curve so far. 1 question which I haven't been able find an answer to is "How do you tell the

difference (visually) between the pre-C, C and K/L lenses for the RB67 range ?" Obviously the C lens have

a C after the word Sekor on the front but the other two ?

 

Can anyone also recommend a good flatbed scanner that I can use to scan negs or transparencies of 6x7

that won't cost the earth and will work on a Mac ?

 

Thanks Andrew.

The C lenses have a "C" written on the front name ring of the lens, the non-C doesn't have anything written on em. The K n K/L are inscribed on the front barrel.

Thanks, where abouts on the front barrel ? does anybody have a good photo example of a K/

l barrel ?

Dear Andrew,

 

Go to Keh.com. In the upper left corner (Advanced Search), click on the down arrow, click down twice, and select Mamiya RB67. The screen will refresh. Then click "Go." The screen will refresh again. Where it says, "Show 10 per page," click the down arrow and select "View All." Then scroll down to a lens like the 75 f3.5 KL L. Click on "Specs" and you'll see a good picture of how the lens is marked.

 

I hope this helps!

 

Best wishes,

 

Mark H.

Also the Epson V700 scanner is great for scanning MF and LF film.
