    My wife and I have both Canon and Nikon systems, although the older DSLR versions. I have the Nikon 105mm and she the Sigma 150mm and the Canon MP-E65mm. Olympus I have the 60mm macro. As we age my wife is thinking about the Olympus (OM System) system. With macro the focus stacking feature with Olympus is excellent. My wife loves to shoot macro and when she is in the mood spends days shooting various subjects. As such I view this lens as a must for macro enthusiasts. Cost, well, how long do you expect to live.

    This lens is awesome!! We finally see something truly groundbreaking again! The MFT system enables these innovations! That's why I believe that the MFT system is the future. Capable of Wildlife, Macro, Underwater, Adventure, Difficult Weather Conditions, Drones, etc… the benefits far outweigh the limitations as the limitations can be bypassed. But the limitations of larger sensors can only be overcome by producing larger and more expensive equipment.

    The clutch is a really nice feature here, I just wish it wasn't focus-by-wire. That implementation makes sense if you wanted to manually focus in conjunction with in-camera focus bracketing features, but I'm sure it could have been engineered differently.
    As for the focal length, this was quite curious for me since most macro lenses favour the 80-120mm range in 35mm equivalency. Having used the Canon 180mm a number of times, it's good at what it does - including placing elements in the foreground to fall out of focus and create a gradient of sorts over part of the frame. I've just never found the focal length to be a "daily driver" macro due to the longer working distance; this is especially true if you are staging shots in studio and you don't really need the larger physical distance from the subject.
    If OM Systems went the other way to 50mm and kept the feature set of this lens the same, I think it would have been a more useful product for most photographers. That said, I understand that such a lens would directly compete with their existing 60mm lens and there really isn't anything in the m4/3 space that does what this new lens does.

    Interesting. It sounds like the lens has a lot going for it.

It's quite smart of OMS though, to make it compatible with the teleconverters.

      Relatively useless, unless you focus stack, which you'd have to do manually shot by shot with high-res mode. Photographing a plane with texture overlapping with the focus plane in a singe shot in high res mode could be very interesting. I would also like to know how the teleconverter impacts sharpness, there's the converter itself AND diffraction impacting sharpness together.

      @manicdan481 Год назад +2

      I've played around with my EM1iii with focus stacking and high res stacking, the end result is so much diffraction that you don't gain much. I use the 40-150mm f2.8, with the 1.4x teleconverter, with an 8 diopter reynox. The end result is that I can use a lower MM focal length to zoom in/out for framing or get insanely close with the whole system maxed out.
      The problem is that wide open there are lots of distracting secular highlights, and stopping down adds diffraction real quick. Lighting control is a must, I cover my subject with some white paper and put the flash on the outside of it trying to get the softest light possible, but even then its still a challenge to keep the aperture open.
      Things look great in the 1x-2x macro range, but when I get it up to the +5x range details are getting lost in diffraction, and we really are resolution limited. However my system acts very differently from this one, so it might not be as susceptible to the same issues.

    Good review Chris. I was particularly impressed with the way in which you covered the price of this lens. So many seem to believe that OMS should produce cheap tat: they want the product, but don't want to pay for it. More than a couple on FB were trying to convince me that I should purchase a Raynox 250 for my Oly 60mm macro, or a Laowa 90mm - because they would be cheaper options. Well, I ordered my OMS 90mm at 0600hrs 8th Feb. It will do for me.

    I agree, it is a unique lens. The Canon RF 100mm is about $200 less but what if they made it a 2:1 lens, would it be about the same price? Here this lens is 2:1 with a full frame equivalent of 4:1 without the teleconverters. You could put the Canon crop sensor camera on the Canon 100mm 1.4:1 lens but you are still only getting 2:1 equivalent.

    • @matthiasglanznig9733

      Agreed, although when the RF100 was released it even cost a bit more than 1.500 bucks. So the price went down a bit during the past few months. I'm guessing that something similar might happen with the 90mm 3.5. But overall I'm not surprised about the price, if the Stabilisation and AF work well and the sharpness is good.

The problem is physics and no lens or software can fix the problems that come from optical laws when subject areas overlap within the stack. And even if that weren't bad enough (I have plenty of unsuccessful stacks from a plethora of tests and software to prove that point) the few times you don't run into these artefacts you end up with a result that may well be ok for a scientific documentation but aesthetically they are off as these images lack by indication of depth and size - much like flower pressings of the 18th century.

      @@AnastasTarpanov Show me a single stack where you don't have to invent large subject areas because they were not picked up by the stack - as it is physically impossible to capture the area of the more distant subject detail that is partially obscured by a foreground element. For example look at what happens around the antenna of a bee or butterfly with regards to the legs or wings (whatever is beind). You end up with an inevitable unsharp halo around the antenna. This happens because in the shot where the more distant area is in focus the antenna is unsharp and has a larger magnification ratio because it is closer to the camera than in the image layer where it is in focus.

      F3.5 of this OM should be just fine, I'm sure that the complexity and price of the lens come from making it usable at 2x, while keeping size manageable, otherwise what would be the point :)
      And there is built in IS, low weight, all the bells and whistles of a native lens.
      Maybe there is an effective aperture datasheet somewhere. I'm sure that there are extra optimizations at high magnification, so it's not like old barrel extending macros from 80s where you can easily estimate the light loss with old formula. It's not a fixed 90mm lens on 180mm extension tube ;)
      Anyways, I think this might be the most "luxurious" macro ever built, just too expensive for the common hobbyist like me :D

    Ad Magnification factor: Magnification factor of 4 at full frame equivalent is wrong: magnification will stay at 2x anyway. Just take a ruler and measure how much you will see on photo and reality. That will stay at 2x anyway.
    Ad diffraction with macro lenses: Also F8 is wrong here.
    Seeing diffraction at F8 on MFT with 90mm is wrong. It starts already on F5.6 according to photopills diffraction calculator at 90mm.
    With macro lenses you have to calculate the effective aperture with magnification of 2x:
    - effective_aperture=aperture*(1+magnification)=3.5*(1+2)=10.5
    - According to photopills diffraction calculator diffraction limit is F5.6
    - therefore diffraction starts already at F3.5 with that lens
    => a lens with major design flaws on MFT system

      Thing is.... IT'S 8x FULL FRAME EQUIVALENT MAGNIFICATION with the 2x teleconverter, not 4x. What is your mathematics with this facts. It changes everything.

    • @te0pol159
      @te0pol159 Год назад +2

      Magnification does not work like that. A 17x13mm subject will fill a MFT sensor on 1:1 magnification and a 35x24mm subject will fill a FF sensor on 1:1 magnification.
      Therefore you need about 2:1 magnification on FF to get an 17x13mm sized subject to fill the sensor and only a 1:1 magnification on MFT.
      1:1 on MFT is 2:1 on FF and 2:1 on MFT is 4:1 on FF.
      Your calculations on effective aperture are wrong since we're talking about a telephoto lens here. With longer lenses you need to add pupil magnification to the equation:
      Effective Aperture = Lens Aperture x (1 + Magnification / Pupil Magnification) = F3.5 x (1+ 2/0.5) = F7
      I'm assuming the pupil magnification is 0.5, since I can't calculate / get info on the pupils on the lens and most telephoto lenses are around that number. The Canon 180mm macro is at 0.5.
      So, the effective aperture at 2:1 at F3.5 on this lens is about F7.
      So, you're right, diffraction starts at f3.5 in theory, but I've happily used effective apertures of F8-11 in my macro shots without noticing any loss in sharpness. In macro, almost always the DOF overcomes the sharpness issue anyways. In my opinion, the diffraction limit on MFT is F8-11 and F16-22 on FF and most people seem to think so too.
      This lens is actually the sharpest at F5.6 (effective aperture of F11.2) according to Lenstip:
      www.lenstip.com/644.4-Lens_review-OM_System_M.Zuiko_Digital_ED_90_mm_f_3.5_Macro_IS_PRO_Image_resolution.html
      *(Don't take the numbers or the text on the review literally, they're mostly bullcrap. This is just to point out the fact that F5.6 seems to be the sharpest aperture setting.)*
      Edit: I was wrong, I just remembered that the lens has some weird motors inside and the lens becomes F5 at 2:1. So the effective aperture at 2:1 is actually F10, so it does have some noticeable diffraction at 2:1. I still wouldn't say that the lens is flawed. It's not really possible to prevent diffraction at 2:1 since with bigger apertures you would need to stack tens if not hundreds of images to get decent DoF. Laws of physics can't be broken, which sucks. Between 1:1 and 2:1 is probably where this lens actually shines, this lens seems to be surprisingly sharp.

      @@te0pol159 Thats wrong:
      AD: Therefore you need about 2:1 magnification on FF to get an 17x13mm sized subject to fill the sensor and only a 1:1 magnification on MFT. 1:1 on MFT is 2:1 on FF and 2:1 on MFT is 4:1 on FF.
      You miss that on fullframe the virtually photographed "ruler in mm" will be also as twice as large on FF and therefore the ratio between sensor size and object size will be the same magnfication on FF and MFT.
      AD: Effective Aperture = Lens Aperture x (1 + Magnification / Pupil Magnification) = F3.5 x (1+ 2/0.5) = F7
      Your calculation is wrong here (assuming your formula is correct): 2/0.5=4 and not 1, therefore effective aperture gets even worser: F3.5 x (1+ 2/0.5) = F17.5!
      If aperture is F5 you would get an effective aperture of: F5 x (1+ 2/0.5) = F25!
      Regarding link from lenstip: You clearly see that already at F8 diffractions kicked already in and reduced sharpness already.

      @@floppyfloppler Oh right, I'm an idiot. The effective apertures are quite bad then. What I realised now, the lens should be at least F1.4 to have effective apertures under F8, but the DoF would be incredibly thin, walking around the lens could be problematic. The F5.0 aperture might actually make the 2:1 usable. Again, laws of physics suck. What I don't know is that if effective apertures need to be doubled to convert to FF though. So if an effective aperture of F8 is actually FF equivalent of F8 amount of distortion or F16. Would be great to know, but I doubt really anyone has that information except optic physicists.
      And true, the lens introduces some distortion at F8 but none at F5.6 like PhotoPills is suggesting. F8 is equivalent of FF F16 after all.
      The magnification stuff is right, you can find articles on it. And it would be false advertising, which is illegal and I doubt they would do that.

    And no, Chris, it is not totally in line with other macro lenses, this is the most expensive traditional macro lens on the market not counting some stupid leica or zeiss lens. Using that MISLEADING "msrp" screenshot to push the narrative from whatever corner you dug up of an EF lens released in 1996 is pretty low of you. You can get that lens for 500 usd nowadays.

      Olympus/OMDS has the best bang-for-the-buck products out of all brands if you exclude Laowa. OMDS' lenses especially are one of the best I've ever seen. The cheap ~$300 F1.8 lenses have better IQ than most Canon 'L' lenses. It's incredibly impressive, because the sensor and lenses are small, so any small imperfections will be magnified.
