This is the best DT macro lens Sony has ever made, but it's also the only DT macro lens, so I guess that's not really bragging it up! The little Sony DT 30mm F/2.8 macro lens does a very good job at producing very sharp close focus shots, in fact, it did a slightly better job on the stamp shot than the Sony 50mm F/2.8 macro lens. There are a couple of issues though, the first is the very short subject to lens barrel distance of 19mm at 1:1 or full life size macro, which is generally too short for field work, but you don't always have to get that close. The second issue is it needs to be focused perfectly at long distances to get the sharpest shots, so you may need to manually focus and review if you're picky about getting the absolute sharpest image. If you don't look at your images at huge sizes, don't worry about this.


The lens is a little soft at F/2.8, but sharpens up nicely as you start to close the aperture. At macro distances, F/5.6-8 looks great. The corners are not quite as sharp as the centers at longer distances, but at close focus they look fine, see the stamp shot. Color fringing is very low, and so is flare and ghosting. All things considered, this lens does a very good job, especially for the price.


Prime lens possibilities. The Sony DT 30mm F/2.8 macro would make a decent choice for a prime lens, although it does require a stop down to get sharp, and works best at close to medium distances. If you're on a budget, and can get by with the focal length of the Sony DT 50mm F/1.8, use that lens, it's much faster, and sharper at large apertures.
