    It reminds me about shepherd's outer garment. 🙂

    That’s great detail and lovely colours in the scales, and an unusual pose too😀

    But it’s not real, it’s been stamped by the maker on the antenna

    How was it shot ?

    What do you mean by: "it’s not real"?

    I thought it was interesting to put the logo on the antenna.
    In this version, I put it elsewhere. Is it more real now?😀

    Sony a6300, reversed 50mm lens on 90mm macro lens, some macro tubes, two diffused lights, ~90 stacked images.
    I collected more images, but I didn't use them all.

    The framing was wider, but I made a crop to highlight the details.

    i've never tried reversing a lens on a lens, its definitely working for you, thats definitely a keeper - i'd put it on DPR before it goes

    logo is harder to spot, if you'd not said it was there id have missed it :)
    it is in a better place though, less distracting

    Really liking your results, the contrast and colours are gorgeous.
    What lenses are you using for the reversed coupling?
    I have been trying this out using some old legacy glass from the 60's(Pentacon 135mm f2.8 and 28mm f2.8 Prinzflex + bellows) which is fun but the diffraction and possibly the lack of decent multicoating seem to be taking a toll on the quality and detail.

    I used a Nikon 50mm series E lens (reversed on a Sigma 90mm macro lens), which offers exceptional image quality and has the great advantage of having a simple, compact construction and with the front lens positioned at the edge of the mount. This is important because the gap between the front lenses of the used objectives is recommended to be minimal.

    I also obtained very good results with the Nikon 50mm lens reversed on a Nikon 200mm telephoto lens.(both on the Sony camera with adapter)
    ............................................
    I forgot to mention the fact that the montage was made from medium quality JPEGs, at half the resolution of the sensor (to get the result quickly). The difference in quality compared to the use of images collected in RAW and at the full resolution of the sensor is very large.🙂

    Many thanks, I think and as you have pointed out I was getting a lot of degradation from the gap between the two front elements of the lenses. I was using a bunch of step up/ down rings to achieve the coupling and they were adding up to quite a gap, nearly 2 inches between the lenses.
    Got some more appropriately sized coupling rings today so I can directly connect a handful of lenses I have and straight away the improvement with my 150mm/55mm combo was apparent.

    Almost 50mm gap is enormous.
    Please post some examples, just to observe the results from a technical point of view, out of curiosity. 🙂

    I got a ruler out and my guesstimation was pretty off, there was a total of 34mm gap due to the step up/ down rings/ coupling ring, that doesn't include the recessed distance of the two front elements just the rings. The results from that can be seen in the first image of this thread although that is a huge crop and being a numpty I forgot to remove the UV filter from the front of the reversed 55mm which further increased the gap.

    The full head images in that thread I had removed the UV filter to see if the IQ improved.
