Maybe consider combining the extension tubes with a quality close up lens?
Seeing as how you've reversed some non-macro lenses, I don't think a perfectly flat field is what you need (but my experience with close up lenses can reveal very good performance across 2/3rds of the frame at f5.6 on 50mm lenses).
And a close up lens will allow to work at a higher effective aperture, which is important.
That's a great idea. but in practice, I've not found it practical from what I remember. I've tried extension with a close up lens by Nisi for about $75 on a 320mm lens. It was surprising to me, because any existent loss of image quality wasn't noticeable to me with the close-up lens. also, the extension tubes together didn't seem to cause, for me, a noticeable lack of image quality. It was the Fuji 50-230mm 2nd version.
The extension tubes definitely worked on the 23mm Viltrox, but by the time the focus was about 1mm away from the lens, the magnification despite the close focus was only 0.4X. For the close-up lens to work to achieve 2X, it would require a focal length of ~400mm or more.
With a Raynox 250 on a 55-250 lens at 250mm on a Canon 70D I get a tiny fraction less that 2:1 (11.5mm scene width with a 22.5mm sensor width), with a working distance of around 115mm.
The close-up is in a way the opposite of extension tubes. An extension tube works more effectively for a wider angle lens, but a close-up lens is more effective for a longer focal length.
True.
That being said, it might work differently with an SLR.
I don't think it is different with a dSLR.
I've been wanting a Raynox 250, but was trying to figure how I'd mount the thing to a 52mm and 49mm lens. Not saying that it's not possible, but probably simply haven't found the exact accessory that I might need. seems pretty good for a 250mm lens! The reverse lens technique can work differently to some extent for an SLR. It could be that extension tubes and close up lens might be working the same as for mirrorless. If I can somehow find how to do with a Raynox, I might finally make it work. BTW, is the 250 the strongest close up lens?
