This means you can fill your composition with something that’s a mere 8.5 millimeters wide (about a third of an inch) on a Micro Four Thirds camera. By comparison, a more common 1:1 macro lens can only fill the frame with something roughly 17 mm / 0.67 inches wide on Micro Four Thirds. That’s a huge difference for photographing small, unusual subjects like hairs and pigment cells on tiny animals. OM-1 + OM 90mm F3.5 @ 90mm, ISO 100, 1/200, f/7.1 That said, the sound of the autofocus motor reminded me of dial-up internet. Grrr—ehhh—rrr-eeee. The motor isn’t going to be audible across the room, but tiny subjects might take notice of the noise. Focus Limit Switch sets the focusing range to define focus limits to enable faster focusing when shooting, improving AF speed.
The 90mm is almost 9.5 ounces heavier than the 60mm macro. This is a Pro lens with Sync IS and improved weatherproofing so the extra weight makes sense. But if you a looking for a lightweight lens, the Olympus 60mm macro might be a better fit. Sharpness was sometimes an issue at extreme magnifications, but not due to the sharpness of the lens – instead, it was due to the depth of field. At high magnifications, depth of field is always an issue because it’s inherently narrow. You’ll need to stop down to apertures like f/8, f/11, and f/16, which have increasingly more issues with diffraction. All of this will sound familiar if you’re a macro photographer, because it’s true of every macro lens. The lens is built with a metal mount.There are three switches on the side. The top is a focus limiter with three positions: Macro, 0.25-0.5m, and 0.25-infinity. Below is the image stabilization switch with On and Off positions. Below it is an L-fn button which can be customized to your needs.The build quality of the lens is excellent, built to match equally rugged cameras like the OM-1, with IP-53-rated weather resistance. Hopefully, OM System won’t mind reading that I’ve felt completely at ease using the lens in the rain and dirt over extended periods.

Enjoy viewing the fantastic work being done by thousands of photographers all over the world—and add your images to the enduring collection.The OM System 90mm f3.5 Macro IS Pro proves that the Micro Four Thirds system still has clout in an era of full-frame mirrorless. This macro lens does what a full-frame camera can’t do — use autofocus at a 4x equivalent macro. The 90mm is the kind of landmark lens that may even be big enough to sway some photographers over to the Micro Four Thirds system. 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 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. Add one of our teleconverters and you have up to a 4x (8x 35mm equivalent) macro lens capable of capturing an unseen world invisible to the naked eye.
In particular, when shooting at2x magnification with the OM System M.Zuiko 90mm f/3.5 Macro IS PRO, the tip of the lens is about 6.5 cm / 2.5 inches from the subject. At 1x magnification, this distance increases to 9.5 cm / 3.7 inches. The 90mm lens has the equivalent of a 180mm focal length and a 4x macro reproduction ratio on a full-frame camera. Perhaps the biggest threat to sharpness is the natural movement of the subject, which is bound to happen with outdoors subjects. Even a millimetre shift in a breeze can be a threat to perfect sharpness at this close proximity, so you might find you want to try shooting at faster shutter speeds and upping the ISO as a compromise. if by working aperture, you mean the aperture being set and used, which I usually refer it to as nominal aperture, to differentiate it from "effective" aperture -- it is something that is physical[edit],limited by the edge of glass or edge of iris]/edit], rather than "calculated" or "derived". I was excited to work with a 2:1 macro lens optimized for Micro Four Thirds cameras, because I believe it serves as a reminder that the Micro Four Thirds format should not be slept on. Despite having limitations due to the smaller sensor size, the format has its advantages, and macro photography is one of them. You can fill the frame with tiny subjects more easily with the OM System 90mm f/3.5 Macro IS PRO than any other camera + lens combo on the market today.The optical formula comprises 18 elements in 13 groups and includes 2 x SED elements, 4 x ED elements, 1 x HR elements and 1 x Super HR elements. It’s amazing that the 90mm macro weighs only one pound considering the abundance of glass. When I was using this lens at moderatemagnifications – say, 1:2 or 1:3 – I felt luxuriously distant from my subject. This made it less likely that I’d scare my subject, and most of all, it gave me a lot more flexibility with my lighting equipment. At1:1 magnification and even 2:1, I felt I had enough space to light my subject effectively. That said, at image magnifications significantly beyond 1x (in 35mm terms), resolution generally becomes more and more of an issue due to diffraction. 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.
In particular, here are what my autofocus speed tests showed. I tested the focusing speed of both lenses from 1x to 0.5x magnification. After 10 replications with each test, the OM System 90mm f/3.5 Macro IS PRO grabbed focus in 5.8 seconds on average, while the 60mm f/2.8 grabbed focus in 5.2 seconds on average. (I also wonder if a newer copy of the 60mm would be even faster, since as I’ve said, mine has seen some things.) Manual Focus Clutch mechanism allowing rapid transition from AF to manual focus. Also features a guide shooting magnification for use when shooting with manual focus. Even with those limits, at 4x macro, there’s still only a very small slice of the image in focus. This lens will break a fancy depth-of-field calculator because it’s too small to measure in hundredths of a meter. The margin for error is essentially non-existent at the closest focusing distance and f8. I was initially worried about that aperture limitation, but became less bothered when actually using this lens because the depth of field is so narrow.The price is steep for casual snap shooters, but it’s well worth the dollar for serious amateurs and professional photographers. Despite a long ungainly name like M.Zuiko ED 90mm f/3.5 Macro IS PRO, this exciting new Olympus lens is only 5.4 inches (136mm) long and weighs just 16 ounces (453g). The girth (2.75 inches / 69.8mm) is slim as well, as evidenced by the 62mm front filter thread. It’s nicely balanced on a Micro 4/3 body and has an exterior finish that matches the Olympus OM-1 that was used during the evaluation; in other words, it’s excellent. 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. If you don’t round up to the nearest ounce you could say the Olympus 90mm f/3.5 macro weighs less than one pound. In any case, it’s the lightest weight lens in its class and tips the kitchen scale at 15.97 ounces (453g) without lens cap, rear cap and lens hood. What's clear is that it depends on the lens. It's widely agreed that the 2x TC is less-than-impressive with the 40-150mm Pro. Also what Hubertus said about the Pany 50-200 is true while the Pany 2x TC works well with the Leica 200mm.
