Yes let’s keep it factual. I only stated benefits that are related to the focal length and how this would be advantageous in certain approaches to shooting. It’s not a personal view, it’s understanding the practical applications for this lens.
Putting a shorter FL 2:1 macro on FF and cropping will require a hi resolution sensor to match the focal length and IQ of this lens on a 20mp MFT sensor would require a 90mm 2:1 on a approx 80mp FF sensor cropped to 20mp.Want a new Macro Lens? Look no further! The OM System M.Zuiko ED 90mm F3.5 Macro IS PRO Lens, designed for Micro Four Thirds System offers up to 2x magnification. Ultra-high magnification shooting and more magnification than on any lens we’ve ever made. Increase that magnification up to 4x2 with the addition of the optional MC-20 2x teleconverter (sold separately) to capture an unseen world, invisible to the naked eye. I said I could see the advantages of an 180mm, I never said it was necessary. I even stated it wasn’t necessarily for myself and a specialist application. That doesn’t mean I cannot see the advantage. Yes you can make great images with shorter focal, I never said you couldn’t. I have only implied that choice is good and this choice is not available on FF. It’s available on MFT due to the inherent benefits of a crop sensor.
Roland. More pixels indeed means more noise. However with macro photography we are more often than not chasing more DOF, this would essentially negate the 2 stop noise advantage offered by FF. Cropping a hi resolution FF to match the FOV of this lens on MFT would also crop away any noise advantage offered by FF. Draw a 4*5 grid on an A4 sheet of paper and then the same 4*5 grid on an A3 sheet of paper. Both sheets of paper (the sensors) now have the same number of pixels despite one being bigger than the other. Now put a pattern (the same image) on each, just as you stated in your example. Then try and extract more detail from the smaller sheet by cropping and let me know how you get on. It’s called pixel density. PPI (pixes per inch) and this comes into play as soon as we crop inside 20mp in my example.
It’s the kind of lens that, if macro is your bag, it will make you fall in love with the genre even more – especially once you get used to how it works. Being able to get super close to your subjects and record them in stunning detail, all while shooting handheld and benefiting from such a high level of magnification means you can quite easily get lost in miniature worlds. Improved Art Filter selection allows for easier and more intuitive with effect visible in Live View Focus clutch on my 17mm f1.2 Pro, 12-40 f2.8 Pro and 8-25 F4 Pro all work on my Panasonic camera bodies, and they are old camera bodies (GM1/GM5). Something comparable from full-frame competitors would weigh significantly more, take up much more space in your kit bag and almost certainly require a tripod or other method of stabilisation to keep subjects pin sharp. They’d also likely be more expensive too.
I also find that the 50mm FOV on MFT is ideal for me for both portraits and landscapes, so it’s really a nice lens to have on my camera all the time. Finally, this new lens is more than twice as heavy as the Laowa. Sorry for the confusion, flash does not change the minimum focusing distance. I was noting how a greater minimum focusing distance allows for more lighting flexibility so that the lens does not get in the way of a large diffuser. This lens is sooo versatile, with more than Super Macro to telephoto (180mm 35mm equivalent or 252mm with the MC14 teleconverter, or 360mm with the MC20 teleconverter)” so many subjects to use it on.”Now, super high resolution is seldom a demand for macro images. So, a smaller sensor and smaller lens might be an advantage. But, it is a choice. If you think bigger cameras is not a problem, then you might get better images with a larger camera. And they *did* shoot the 90mm at macro distances, including closest focus, with and without 2x converter, and they show fullsize images, which very much support the lpmm results. Enrico, the increased field of view obtained by pushing down is often important. And the fact that it will out-resolve the sensor means that pixel-shifting can be used. Pictures are taken on a digital SLDR camera of a medium or high class with an 8-12 MPix APS-C/DX or 4/3 detector (Canon 20/40D, Nikon D200, Pentax K10D, Olympus E-3 or Sony A100) and with an 21-25 MPix full frame cameras such as Canon 1Ds MkIII, Nikon D3x or Sony A900.” The 90mm lens has the equivalent of a 180mm focal length and a 4x macro reproduction ratio on a full-frame camera.
