p.2 #3 · Best macro lens for jewelry photography? | |
Hi,
Yeah, that's why the 60 is going back - Unfortunately in my main application for the lens I'm effectively using the D800's images at 100% (the items are VERY contrasty, and you actually can see the detail loss when they are downsized, the CA sticks out like a sort thumb, etc). I put up some test images for the repair guys if they care. Again, I'd prefer to use other methods to get around these issues, but....
The first is a test image I use a lot to check for big stuff like bad corners - you'll note the upper right corner (and I actually need the corners - see below) is a bit softer than the other three:

On the CA issue, the next two are un-tweaked/sharpened crops of something I was shooting - the first is the 60, and the second is a 50mm f/1.8D for comparison. If you look along the back edge of the piece, you can see the difference in CA - there's also some subtle stuff like the color of the tang has changed slightly because of the CA off of all of the edges on it, etc. but that's not an issue in print in this case (downsizing is sometimes your friend).

And here's one shot with a 50mm f/1.8D for comparison - Its not as contrasty, but the CA is small enough that I can get away w/o heroic measures to remove it and interestingly,with careful sharpening, you can pull up the detail so its about the same as the 60.

Again, this particular application is kind of a lens torture test, but I have run into similar issues with jewelry in the past as well, depending on what the client wanted the piece to look like. In most other applications, its nowhere near as important (and obviously w/ lower resolution cameras, this is kind of a non-issue - it seems like this step up 36 megapixels is kind of a "bridge too far" for most of the existing 35mm slr lenses - all that stuff you were blissfully unaware of is now in your face...).
Best,
rkg

EDIT: I forgot to use links to the images initially - sorry about that.

The 105mm F2.8 AFD is another option, excellent optics, but avoid F16. Personally I would avoid a 150mm lens, you might find too much working distance, and end up at the edge of the room. It depends on the size of the items of course.
Lighting wise, the Nikon macro flash is excellent, and you can also use an on camera flash with a plastic diffuser, as I am sure you know.
As you clearly know that lens should not show much CA. I have both versions - AFS, and AF - and I have never seen CA in 20 years of using the AF, and 2 years using the AFS. Neither has soft corners when stopped down, the AF is said to be a bit soft wide open at infinity.
