I received a nice copy of an APO-Rodagon D 75/4 1:1 Macro lens in the mail recently and have taken some more comparison pictures. I had to adjust the lighting a bit given the shorter focal length and re-took photo of my scarface 57D Lincoln Toner with the Printing Nikkor in same lighting setup for c...

I have a Rodenstock Eurygon 35mm that has a ~39.5mm thread. Is this for Copal #0 mount? If so I'll need to look into that adapter... No, Copal #0 is M32.5x0.5, Copal #1 is M39x0.75, see here http://www.skgrimes.com/products/index.htm I remeasured the Eurygon and it is 40.0mm, corresponding to the f...

Check out the StackShot rail by Cognisys . It's an automated rail with about 4 inches of travel and enough resolution even for use with microscope objectives (see 40X with a StackShot rail ). --Rik Wow, I have seen some of the discussion about StackShot but hadn't looked further. Looks perfect, tha...

Anyone have experience with the Nikkor-AM 120mm Large Format lens? The AM is "APO Macro", sounds intriguing. How hard are these LF lenses to adapt to SLR type mounts? Adapting isn't that hard, Schneider sells a Copal #0 to M39 thread adapter, from which it's easy to adapt further (the rear element ...

It's a beautiful lens but the narrow magnification range, large diameter, and short working distance make it extremely impractical. It also has large and odd mounting threads. Yes, it's a pretty specialized lens and couldn't be recommended for general usage. I think your printing Nikkor is probably...

Talk about narrow depth of field...any idea how good this lens is? No, and there are very few users out there... see this http://homepage2.nifty.com/akiyanroom/redbook-e/repro/repro1pon.html Well, I tested an 85mm Repro-Nikkor and found it a very odd lens. It's NOT a camera lens! It wants to be mou...

Realistically though, I dont' think you'll really beat the printing Nikkor. If you truly want higher quality, moving to bigger formats should be a more efficient use of time and resources than trying to find something better than a printing Nikkor. You could of course consider stitching several ima...

Talk about narrow depth of field...any idea how good this lens is?

Yes, this is true. To fill the sensor with the same sized subject, you need 1.5x the magnification. The larger image circle (22mm instead of 15mm) isn't really a stress on the apo-rodagon-d, however, as it is designed for a 40mm radius circle. We'll see...I plan to buy one and compare flatness to t...

Note too that this depends on the optimum aperture for the lens, and also on the sensor. A lens which is optimum at f/8 for example would give 522μm. Change the D90 for a D3 or D700 with its larger, 8.45μm photosites and that becomes 803μm at f/8. But for the D3 or D700 the magnifica...

It is a cast bronze coin, or 'potin'. Gaulish, of the Remi tribe (from the area of France around the modern town of Reims). Unlike your ancient from Gaul, most modern coins are pretty flat and unless the coin is not flat on the stage or the camera not mounted square on the stand I have not seen a s...

I suspect you're right about thte AA filter - some have them removed from their D3X cameras. :shock: We'll all have 50, 100Mpixels soon, then your PN will be in its "element"! my 55/2.8 Micro (and 55/3.5), I found the 2.8 to be sharper than the 3.5, contrary to some reviews. Did you? Yes, the 2.8 i...

OK which is best from these - not so easy huh? Actually, the D75/4 is the clear winner of the 3. The only thing making the decision difficult is the 55 Micro scale is smaller so resolution is harder to compare, but the D75/4 has better contrast. Step back 6-10 feet from your monitor and the compari...

M=1, 75mmf/4, yes. The same lens or its twin was used here where the limiting factor was the sensor. Have you tried a 55 f/2.8 micro? I've compared with my 55/2.8 Micro (and 55/3.5), but they are inferior both in center and at the edges compared with the PN and AEN. That 75/4 may give the exotics a...

Also these are short stacks - sometimes an individual frame looks slightly sharper. These differences are as a rule insignificant , to me. There's always other things - like here the lighting, which needs improvement first. I imagine you have a standard way with coins. I used a diffused flash one s...
