Micro 4/3 for Macro/Close up Photography

    I'm currently suffering from a bout of bad G.A.S. and contemplating getting a micro 4/3 CSC for my butterfly shots. Am I right in thinking the smaller sensor will be beneficial for this type of photography, both in magnification and managing depth of field. What are the potential disadvantages?

    I had a m43 system a few years back
    Close up macro would be ideal as you say the smaller sensor will give much better depth of field. whether the flash capabilities are a match for canon - I would seriously doubt it.

    You get extra depth of field (a bit) and IBIS will counter more varied movement than lens stabilisation. There is a bit more pressure on lens resolution because the starting point is a smaller image but that is probably negligible with modern lenses.

    Can I just add
    Last year when I had a crack at insects using both aps-c and FF with the 35mn macro stm and 60mn f2.8, dof was rarely a issue. May I ask what you use for macro now??

    Martin already uses the best you can get! This is a case of iwantitis.

    “Best you can get” which is??

    I currently use a 7d2 with a sigma 105mm macro. To get sufficient DOF for the butterflies I'll typically need f11/f14. Unless I've got things totally muddled, with an m43 and a 60mm macro lens I will get similar DOF at F5. 6, which means I can shoot in lower light of at higher shutter speeds.

    Could you not try the 35 stm IS, amazing lens, I don’t know how close you get to the butterflies but the dof on the 35mm is pretty impressive. I might have a go tomorrow.

    I currently use a Nikon D800 and Nikkor 105mm macro (I don’t usually use flash).

    I wouldn’t want to revert to a shorter focal length; butterflies don’t often stay put for me to get to 1:1. (I previously used a D90 with its smaller sensor and 85mm DX macro, and before that a Pentax film SLR with a 50mm “macro” that only went to half size).

    I would value the more comprehensive stabilization of mirrorless.

    I think the pixel pitch is more relevant than the sensor size; I’ll usually take a few shots as I gradually move in closer, and am happy to crop the best shot I get if there's more in the frame than I want. Smaller pixels mean better resolution in the focal plane, but worse image quality at a given ISO.

    I think “extra depth of field” with m43 is rather a myth. My 105mm goes down to f/32, which is reported as f/57 at 1:1. Using that would be sacrificing more light admission and accepting more diffraction than I’m prepared to accept for butterflies (though I have used that aperture on some subjects with a tripod), and I’d meet the same compromises at f/16 with m43.

    Although I value lens resolution in principle, macro lenses, being primes normally used at relatively small apertures, are generally very good, and I suspect the difficulties of getting a butterfly accurately in the very narrow focal plane mean that I would have to be very lucky to get a shot that was limited primarily by the quality of my 105mm, or any other decent macro.

    I guess my ideal kit would be the Sony α7R IV (which has a similar pixel pitch to the previous generation of 16MPx m43 sensors and excellent low-light performance) with a rather longer focal length macro than the 90mm Sony offer. When Nikon launch the 105mm Z mount “Micro” in their roadmap, I’ll find that with the Z7 or its successor very tempting.

    Well the deed is done and the itch has been scratched. I took advantage of the many deals on the Olympus OM-D 10 mkIII around at the moment. It was a bit of a no-brainer as my wife is starting to struggle with the weight of her dslr, so she thinks I was only thinking of her best interests with the purchase.

    Which of course you were! I hope she lets you borrow it from time to time.

    No need to justify
    You succumbed....don’t dare lecture me in the future;)

    You might as well go the whole hog and grab those matching lenses :eek:

    Smart move. You’ve learned the ways Grasshopper, now go into the world and use your talents. ;)
