High end zoom lens for tube lens. Vignetting?

I currently use Mamiya 645 prime lenses as a tube lens for photography with infinity objectives. I was wondering if anyone has experience using a high end zoom lens as an adjustable tube lens. I'm considering a Canon 100-400mm II L. At any given zoom length its much sharper than my Mamiyas. I'm conc...

Very nice image of a difficult subject. I tried a stack of one of these years ago that ended up in my recycle bin. But you did a great job with it. I caught one on video last summer. They're funny little things with a whimsical kind of movement. https://youtu.be/Ob6tESvi6FY?t=69 The mite comes in at...

Rik is correct regarding my settings. I'll test this again, hopefully tonight, with the recommended settings.

Macrolab- those numbers are astounding! I'm hoping I can achieve something close that

Thanks everyone. Rik, sorry for the trouble and thanks for the correction. I don't post often and had forgotten the protocol. I checked preview to see that the photos displayed and assumed I had it right. I've removed the img tags. I put spaces after and before the [/url] and [url=, but in preview i...

Thanks Jens, Lou and zzffnn. Jens, I'd have some too if they tolerated the cold better. I'm not sure how well they'd get along with our chickens. Here are some new photos. I tried a Mitutoyo 5x for a couple shots. Also, the detail from these reduced images really doesn't show the resolution of the i...

Thanks, and I agree it is an amazing adaptation.

These were all taken with the same setup:
Canon 5D Mark III w/ magic lantern hack silent photo mode
Mitutoyo 10x 0.28 M Plan Apo objective
Mamiya 645 210mm f4 lens

Thanks everyone. Beatsy, you should, the colors and structure are very interesting. I ordered 10 feathers from ebay for $1USD. These are the natural colors. Saturation, contrast, sharpening was adjusted to taste, but there was no masking or artificially changing colors. I'm still not satisfied with ...
