If this is the case, you’ll want a longer focal length, so you don’t have to get as close to subjects and risk disturbing them (i.e., choose this lens over the 50mm macro). This is important to note if you are photographing moving subjects like insects. In other words, the lower the focal length number, the closer to your subject, you will have to get to achieve the 1:1 reproduction ratio. Lower focal lengths will have smaller minimum focus distances, and larger focal lengths will have more significant minimum focus distances. One thing to note is that the minimum focus distance of most macro lenses is a factor of focal length. 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. On first impression, the Sony 90mm f/2.8 Macro seems very well built.
