Ray,
When using a lens like this, and to get the magnification shown in your pics, is a relay lens necessary? Could one use this lens on a bellows setup and achieve the same, or similar, results?
Could you take some pics on a <$300 bellows setup, get in ultra close to the mint mark, and post here? Would like to see results.

Andy...yes, no tube lens is needed. The two pics above are done both ways, with and without tube lens. The top pic is the "normal" way like you'd get with the <$300 bellows setup. The bottom one is with the tube lens. There is only the slightest benefit to using the tube lens...Ray

Well duh, I missed the parts that the pics were done with/without. Thanks for clarification.

Are these the lenses? Is there a difference between the two?

Same lens optically. I have examples of each, but the bottom one is easier to use. The hood on the upper one is not removable and can get in the way of lighting.

Ray,
If one wanted to pick up one of these to try out, what do you think would be a reasonable cost? I'm debating on it.....

I think $60 would be a very good price. They seem to sell typically for $75 or more.

The 35mm Tomioka Tominon (35TT) is a similar lens to the 35RE, and was also built for the Polaroid system. In fact I think the only Rodenstock lens made for Polaroid was the 35RE. All the other lengths, including the superb 50TT, were made only by Tomioka. I have a 35TT that has a broken aperture that I removed. It now only shoots wide open, which is OK as this lens does fairly well there. I tried it in same Finite and Infinite configurations as the 35RE. Here are the pics: Bellows only, no tube lens:  With 186mm tube lens:  Similar to the 35RE, I expect the 35TT to benefit from stopping down to f5.6, but I ended up testing a lens without this capability. Interestingly, I see more difference between the with and without tube lens shots with the 35TT. This is probably because the effective aperture differnces are larger when the lens is wide open.

For reference, I took a shot of the same coin with the Canon 35mm Macrophoto lens. This lens is good at f2.8 but slightly better at f4. I would think f3.3 might be the actual best but it does not click at half-stops. Here's what it looks like at f4:  Contact me for photographic equipment or visit my home page at: http://macrocoins.com |

Ray, Really nice pics. I can never seem get my lighting that soft and even  If using a 35mm enlarger lens on a <$300 bellows rig, is the bellows going to need to be a max extension to get these closeups? How is yours setup if using a bellows? Is that about all these lenses are good for or can one get full coin pics? |

For this magnification the bellows will need to be full extension. On the other end, even with bellows at minimum extension it will be tough to get below 2:1. I usually can't get below 2.5:1. So, no full coin pics with such short lenses using bellows.

Ray,
When you're taking/posting your close-ups, how do you determine
1)original size to snap,
2) cropped size and
3)resizing for posting here to ensure maximum clarity/resolution?
Is there a formula based on the original size of the RAW? Is it based on the camera's overall sensor or pixel count? Do you go with a percentage of the original or a numeric value?
Seems like when I crop in DPP, then resize after/when converting to JPG, resolution does not seem to be near as good corner to corner as the post you pic'd above. I know hardware is a factor, but I want to get the best out of what I have.
Using a Canon 1000D and various lenses depending on coin size.
Any advice/info is appreciated.

Andy,
My workflow is:
Camera settings: -1/3EV; Av; ISO100; Neutral 0,0,0,0; Live View
Frame coin such that it fills approximately 90% of the frame vertically
Adjust lighting for most aesthetic look
Place Zoom/Exposure box over critical focus area; zoom-in and critical focus the shot
Place Zoom/Exposure box over brightest area of coin
Shoot at L setting (full resolution jpg)
Adjust levels, saturation, and sharpness
Crop square, full height for full coins, or no crop for closeups
Downsize 4x for T2i, or 3x for XS/1000D
