When he put mine together he said the 75mm didn't work well with my stand so he put an 80mm in it.

mcshilling, your stand uses the B&L MZ7 mount to hold extension tubes and helicoid. The minimum extension I was able to achieve was too long for a 75mm to be capable of framing a Dollar. When the minimum extension is too long, the minimum magnification can be too high for full range of coin sizes. With the 80mm, you can frame up to a 42mm coin/medal.
Dar uses a bellows that has a short enough minimum extension such that 75mm lenses can frame Dollars.

I received the Correct 75mm El-Nikkor lens today!  That was Fast. Here are shots of the OBV and REV with the new lens. El-Nikkor  Vivatar  El-Nikkor  Vivatar  I tried to get the lighting as close as possible in all shots. Can you see a difference?

dar very good excellent photo. question these coins they look very perfect. I don't have any American pennies to compare your coin to. my question when you have this coin in your hand. the appearance of this coin is excellent it looks like it has a bronze appearance is this what the American penny looks like in your hand. I took a picture of a bite up American penny it is and older circulated penny. I want my images to look exactly as the coin. I was wondering does your images match your coin or does the images look better than your coin.

Dar...the Nikon is a little sharper than the Vivitar, and a little higher contrast, otherwise look about the same.

Quote: is this what the American penny looks like in your hand It is Very close. I have not done any post processing to the coin so it's just the way I have the lighting I guess. The coin itself looks Better in hand and has more color then the image shows. Quote: the Nikon is a little sharper than the Vivitar, and a little higher contrast, otherwise look about the same That's what I was thinking too Ray. Hard to tell the difference just looking at these photo's. I haven't done so yet but maybe there will a bit more difference when I compare the RAW images?

It's doubtful you'll see any marked difference at other than 100% crops with these lenses. Don't forget, we're only playing with the last 5% here - either lens makes you look like a pro with images small enough to post online. That said, the Nikon will establish its' superiority at full size once you've dialed it in to a particular coin.
You'll probably see a greater difference just by processing the chroma noise out from a RAW image, which will somewhat homogenize the surfaces. A little sharpness will be lost, but you have sharpness to burn with this kind of rig, and the final look should be closer to "in-hand."

I doubt the difference will be any more noticeable in RAW. This just reinforces the point that there is not much difference between lenses. Even if you shot the same coin with a 75ARD1 or a 105PN, you will not see a significant difference unless you look at 100% pixel level.

I didn't even think to look at it at 100% cropped. Quote: You'll probably see a greater difference just by processing the chroma noise out from a RAW image, I still have to learn how to do this.

I hate it when I don't see someone's response before responding. Luckily Dave and I are on the same page...

Today I received my Opulux paper, (10 sheets).
I really did not realize just how big each sheet actually is. Wow.
Now I just need some design ideas. I have read the older threads about Smile Directors but there are really no new designs or posts. Can you guys lend me a hand?
Thanks,
Charlie.

I got my Opalux yesterday. It came in a huge outer box, about 2 x 2.5 x 0.75 feet, filled with almost a lawn bag full of plastic packing peanuts. There was an inner flat box containing the 10 sheets.
The paper diffuses about as well as the thin regular paper I was using, but absorbs less light and looks to be slightly whiter and less yellow. Of course, its a lot thicker and stiffer, and might be good for paper cone diffusers.
