If you’re not familiar with macro lenses, a 1:1 ratio allows you to make really cool images of tiny objects! Finding this distance allows you to make objects appear at the reproduction ratio of 1:1. I appreciate the quick (no fumbling) switch between autofocus and manual focus, allowing me to quickly find the minimum focus distance. With a minimum focus distance of 0.28m (11 in) and a focal length of 90mm, this lens can really bring small objects to life! It quickly grabs and holds sharp focus allowing me to get very close to my subject. The focus performance on the Sony 90mm f/2.8 Macro lens is excellent. It doesn’t have a weather seal, but the metal barrel felt like it could take a lot of abuse. When it comes to durability, I think this lens is built quite tough. I’m not sure what makes it a G vs GM lens, but I was delighted with the results with this lens. The G rating indicates that this lens is a top-rated lens in their lineup, but not quite up to the standards of G-Master. This means that it’s one level below the Gold Master lenses from Sony intended for high-resolution cameras like the 61 MP a7R IV. The Sony 90mm f/2.8 Macro is a G rated lens. This button can be customized, but most people choose to program it to eye autofocus (not as useful for a macro lens unless you’re shooting portraits). The last feature on the exterior of this lens is the focus hold button. The Optical Steady Shot function is great if you’ll be shooting at slower shutter speeds in low light. The focus performance is awesome, and I leave the focus range selector on full most of the time. The other switch turns Optical Steady Shot on and off. It has options of full, infinity to 0.5m, and 0.50 to 0.28m. The first switch is for choosing the focus range. On the exterior of the body are two additional switches. The focus ring also has hard stops on each edge which make it easy to find the limits of focus and achieve sharper images in manual focus. When you turn the focus ring, it has clear markings indicated the distance and reproduction ratio (important for a macro lens). This allows quick switching without fumbling for a small switch. It slides forward to autofocus and back for manual focus. I also really appreciate the unique auto/manual focus clutch-style switch on this ring. The barrel is smooth except for a grippy knurled focus ring that feels tight but smooth. Not a heavy, bulky weight, but a sturdy, rugged weight. It feels solid in your hand, and the metal barrel has a nice weight to it. As for sharpness, well, I don't see how I would benefit much from sharper really, from wide open.Īll of this said, for someone who likes 105mm more than 90mm and doesn't mind or use the focus ring of the Sigma I think it would be a stellar choice.On first impression, the Sony 90mm f/2.8 Macro seems very well built. Sometimes I move the camera and lens back and forth, sometimes I focus manually. I also, like D Abbot and others, really like the very non focus-by-wire feeling MF implementation on the Sony 90G. In the end it was longer and lacked OSS and for available light shooting handheld every bit of stabilization helps. I debated between the two as well, and saw the slightly better sharpness with the Sigma. But the Sigma seems to be the better choice.įor sharpness, yes. Not saying the Sony is a slouch in terms of sharpness. For macro work, I tend to move the camera rather than the focus ring, so Sony’s advantage has not been a factor, for me.ĭustin Abbott, Christopher Frost and a couple of others have reviewed the Sigma and it is indeed sharper than the Sony 90mm.Īnd Dustin had just reviewed the Sony a couple of weeks before the Sigma. I find the CA’s to be much better with the Sigma. The effective sharpness of the lenses is similar in the center (although the Sigma has the edge), but the Sigma is much sharper across the field. I still want to do some 1:1 tests for my repro needs, but so far it looks like a keeper. I went with the Sigma and will write a quick review on that thread sometime later this week. The decision seems to be mainly on whether you need OSS or not, although there is also 100g weight saving and better manual focus implementation on the Sony. The FE 90 has a bit less vignetting when stopped down, but it seems that for everything else the Sigma has an upper hand optically. The CA control wide open is also better on the Sigma, although the FE 90 is also quite impressive in this regard. I don’t have experience with the FE 90, but I opened a thread on the same topic a week ago.Īccording to lenstip the Sigma is sharper, in fact it is the highest resolving lens they’ve tested and it has beaten the record previously held by the Voigltänder APO 65/2 (see the link in my original post).
