I don't think any of those are RPMs. Best way to familiarize yourself with what RPMs look like is to browse the VarietyVista website, and look...
The Sigma 150 is a far better choice for coins than the 105VR. It offers much more working distance, and a tripod mount. The 105AFD has most of...
But when you are shooting small coins with the 105VR, it is difficult to achieve high angle lighting. Only way to do it is to place the lights...
The 40mm is sharper than the 105mm, but the working distance is even smaller, so high-angle lighting is harder to achieve. The OP is doing DX....
I bought the same lens back in 2009, used it a few months, and it has sat on the shelf since then. It's big, heavy, and because it doesn't have a...
I'm hoping to find a late die state 1956-D RPM#1 LWC with the BIE. They seem very elusive.
I'm curious @furham, what was your motivation for saying this is not an RPM?
I use a Bausch & Lomb Stereo microscope. I used loupes for years, and have a box full of them, but don't even pick them up any more. The stereo...
Well, I am not sure if it helps or not. Your exposure example makes no sense to me. Once over-exposed, there is no recovery of the image data in...
I debated answering due to not wanting to get in the middle of an apparent feud, but it seems to have subsided, so I'll wade in here... I was...
The new online pre-screen submission process looks like it will need high quality photos to help attributers identify your variety or to convince...
I have many extra RPMs and Doubled Dies available from BU roll searching, hope to find folks with similar extras to trade.
Looking for trades of Wheat RPMs, BIEs, and Doubled Dies for similar. Let me know what you have and what you're looking for. I have extras of...
Neato!
It's a good discussion indeed! I also agree that @Denis Richard's photos are excellent artistic renderings, but I do have a concern regarding the...
I was saddened to read this post, as it's sort of a "let's agree to disagree". I wonder how many folks on this forum actually shoot coins like I...
I'll address the points of interest inline below. Sorry for the long post. I mostly shoot Cents at m~0.7:1. At f14 I'd be at EA24 (!!). Even if...
Several things to address here... Using Av mode, combined with exposure compensation, gives a very fast, correct, and consistent exposure, long...
Makes sense. I can take advantage of Aperture Priority mode to adjust shutter speed. How do you compensate for changes in color temperature vs...
I use continuous lighting, so Av mode is possible/practical. I can adjust the power of the lights, but I never do, as it changes white balance....
