Just wondering if there is any sensible way perhaps using an add-on wide angle adapter of actually getting less than 1:1 with an MPE-65 and still get good IQ etc ?
Anyone had any success with this ?

Nikon (and I believe Olympus, perhaps Wild) makes 0.5x auxillary lenses for their stereo (dissecting) microscopes. Never used one.

Have to admit- someone asked this on another forum . They are fed up with changing lenses etc out in the wilds for slightly larger bugs and I idly suggested you may be able to add a wide angle converter but just wondered if it was possible and thought the lens experts here might have some idea.
On a 1.6 crop camera the MPE-65 can be a bit of a problem for general bug shooting and as many people have commented they would happily swap it for a high quality lens with the range from around 0.3 :1 to 3:1 magnifcation rather like the old Minolta macro lens. As far as frame filling goes that's not far off what you get with the MPE-65 on a ff camera body.
The answer also needs to be failry cheap as usual

A divergent achromat add-on lens would indeed reduce magnification (but it certainly affects parfocality and introduces aberrations). The main problem with this add-on lens for the MPE-65 is that it needs to be computed specifically for the Canon lens, and this is something that only a company like Canon can do. Alternatively, one could try a large collection of lenses with slightly different curvature radii and find one that performs best, or least bad.LordV wrote: On a 1.6 crop camera the MPE-65 can be a bit of a problem for general bug shooting and as many people have commented they would happily swap it for a high quality lens with the range from around 0.3 :1 to 3:1 magnifcation rather like the old Minolta macro lens.

I don't have suggestions for low-cost alternatives (aside for the obvious lens-on-bellows solution, which does what is requested), but there are a number of industrial macro zooms made by Optem, Unitron and other companies that cover this range of magnification. However, they are designed for videocameras with smaller sensors and they should be used with APS-C and FF adapters, of quality unknown.

I find a answer, have done routine testing with the MP-E and found the sony VCL-DH1758 (A Sony adapter to increase zoom in compact cameras) wich has a 58mm ring, when placed in front of MP-E is capable to anchieve this.
Would like the group opinions on image quality (but as I did the ruler photos handheld there are focusing diferences). Usualy I don't use this on field (almost all my shoots, at this time are more closer than 1:1) but this answer the questions and have some interesting findings.

MP-E at 3X and the converter in front of it, is a lot extended
Frontal element of the sony VCL-DH175, I tested in natural light condition this give a almost 1 stop gain in light deliverd to MP-E front element, found this using the camera at aperture priority and without the lens for that scene the exposure was 1/50, with the lens in front of it was 1/60, despecting the extra glass the large front element gather light to allow this gain.
I think should be very hard to adapt a frontal flash to this, for flash use the best is a bracket mounted one.
