As I mentioned previously, I felt like there was a much shorter learning curve to this lens than there was when I got my Olympus M.Zuiko Digital ED 60mm f/2.8 Macro Lens. Interestingly, the OM System 90mm f/3.5 surprised me in remaining quite sharp even at narrower apertures. Diffraction still caused some loss in sharpness, of course, but my impression is that the only sharpness loss I saw at these apertures was from diffraction. The lens didn’t seem to contribute any additional issues of its own. You’ll see in a moment how much sharper the 90mm f/3.5 is compared to my M.Zuiko 60mm f/2.8 even when both were are narrow apertures of f/16 and f/14.
The build of this lens is mostly metal, though there are a few pieces that feel a bit too much on the lightweight side. That helps the lens achieve a pretty good balance between the feel and durability of metal without pushing the weight over a pound. My first question is do you have any experience at all with high magnification macro i.e. well beyond 1:1? I do, and have owned and been using the Canon MP-E 65mm f2.8 1-5x lens for 15 years. Nearly all greater than 3:1 macro photographs out of camera look soft. Either because of the incredibly shallow DoF or diffraction softening. You have to use PP regimes to get sharp looking photos. Focus Limit Switch sets the focusing range to define focus limits to enable faster focusing when shooting, improving AF speed.
OM System M.Zuiko ED 90mm F3.5 Build and Handling
In addition, I don't understand your reasoning on its value for pushing down an objective. As you know, the FOV of an objective on MFT with a 90mm tube lens is about the same as the FOV of the same objective on a 180mm tube lens on FF. This is very close to the the FOV you get with the same objective and a 200mm tube lens on FF. In other words, this new 90mm lens, if it does not vignette, almost exactly replaces the 200mm + FF system. That's very useful. And it hardly counts as pushing down, in terms of lines per FOV. Lns per mm is not the appropriate measure when comparing across sensor sizes. Taken with an Olympus OM-1 and OM System M.Zuiko ED 90mm lens, 1/160 sec. at F3.5, ISO 1600. Photo credit: Amy Davies. I paired the OM 90mm macro lens with the OM System OM-1 camera and excitedly headed to the garden in search of tiny subjects of interest, like fungi and insects. It’s a camera and lens pairing that I’ve had a decent length of time with and got a good feel for what’s possible, and the pleasure hasn’t worn off.

Which is absolutely essential in technical matters like this one. crop. Resolution is not the best. This is close to the top margin, and there is a clear lateral chromatic aberration. The target is labeled in lp/mm.In short, the OM System 90mm f/3.5 Macro IS PRO is an exceptionally sharp, high-performing macro lens with great usability due to the large working distance. Once you adapt to the peculiarities of focusing with this lens, it’s hard to beat – and I’d say it’s stolen the crown as the ultimate macro lens for the Micro Four Thirds system. When the EVF Auto Switch is set, you can now select how the viewfinder is displayed when the monitor is open. People are worried about this f/3.5, as they know that a normal macro lens turns 2 stops slower at 1:1 (would be f/7) and 3 stops slower at 2:1 (would be f/9.9). I have the Canon EF 100/2.8L Macro. I don't really use it as a macro as it is an excellent 'normal' lens. Maybe I should try out its macro capability?
I agree with @Quiverbow that even making it something like 25% cheaper wouldn't attract millions of additional buyers. Also we do have to consider, like it or not, that OMDS does not (and, in the foreseeable future, will not) sell as much as Nikon or Canon or Sony, and lower quantities enforce higher prices to break even, it's as simple as that, unfortunately. Whether you have an OM camera from OM SYSTEM or an Olympus OM-D, PEN or any other compatible camera, you'll benefit from all that the Micro Four Thirds (MFT) standard has to offer: a camera system boasting compact size, light weight, more shooting freedom, high image quality and ease of use, you name just a few. Like the flagship OM-1 camera from OM SYSTEM, the ED 90mm F3.5 Macro IS PRO offers excellent IP53 splash & dust proof performance, as well as freezeproof protection to -10°C, allowing the user to continue their adventures without worrying about their equipment, even in the harshest of outdoor environments. Smooth, scratch-and dirt-resistant fluorine coating is used on the front-most lens for easy removal of dust and dirt using a blower or cloth. Pair the M.Zuiko Digital ED 90mm F3.5 Macro IS PRO with an OM SYSTEM weather-sealed body (sold separately) for the greatest field macro photography system ever made. Other features

That’s a 180mm full-frame-equivalent focal length, which makes it one of the longest macro lenses made today. This is important because it offers a huge working distance compared to most macro lenses (AKA the distance between the front of your lens and your subject). You can increase the magnification even further by pairing the lens with either the 1.4x or 2x converter, which boosts magnification to 1.41x/2.83x and 2x/4x respectively. It’s worth noting at this point that at its closest focusing point, the older M.Zuiko 60mm f/2.8 Macro lens boasts only 0.5x magnification. The placement of this focus limiter switch and its ease of use means that with one move of the finger without looking up from my camera I can move in close for Super Macro mode. This is different than the way the focus limiter on the Olympus M.Zuiko Digital ED 60mm f/2.8 Macro Lens which takes conscious effort to get it into life size mode with that spring loaded dial.

Longer Focal Length with Increased Working Distance
As you can see in this butterfly image, and macro and super macro images in general, depth of field is shallow, and there is a general learning curve for DoF for all macro photography. Regarding those alleged more pixel on a subject I explained WHY you are wrong. You can either understand that basic logis or stay in your biased denial. cropping might yield an image that's too small to be useful (around 5 MP). So using TCs is in some cases a necessity"
Great Deal
