Thanks!

Some of the detractors below the above post apparantly have low reading comprehension. The article author was quite aware of and clear about the limitations of the test and made no claim of general applicability. He concluded you need to test your combination of camera, lens, and teleconverter.

No one could test all combinations.

I recently found one combination that totally sucks: Nikon D5300, 55-300, and Kenko 1.4. I won't do that again. And based on that result I plan some controlled testing that will likely lead to me offloading that lens, teleconverter, or both. Both focus and chromatic aberration were terrible. (I know the camera is capable due to my results with other lenses and no telecoverter.)

I was wondering if anyone has tested / compared image's from the 810 cropped to a given size vs. using a teleconverter to achieve the same size?
I use a 1.4 teleconverter often on a D600 and got to thinking if the quality of a cropped image from a large sensor (810) is as good or better than one with a teleconverter used on the same camera, I could then leave one piece of gear at home. And if you're good at reading between the lines, you can see I'm looking for an excuse to buy an 810!

Thanks,

I'm trying to piece together some information on a camera that is going to be given to me. The goal would be to restore it back to working condition (even though I don't know the first thing about doing such...but it looks like an interesting project). The wooden outside case (gray) has the logo mark by Agfa. The lens inside is marked as a Wollensak series iiia 8x10 f12.5 E.X.W.A Betax no. 3.

I'll post some photos of it later today.

According to my mom, the bellows are in rough shape, so I suspect those will need to be replaced.

Where do I go to find out more about the camera?

Thanks in advance.
