![]() While centre sharpness is quite good, the sides and corners are weak - even when stepped down. Sharpness: 7 Aberrations: 4 Bokeh: 8 Handling: 9 Value: 10 Camera Used: Sony A7sĭespite some very serious flaws, there is something about the images produced by this lens that I like. The first two sample photos shoe examples of the flare put to (I think) good use.ĭSCF1048a Sigma 28mm 2.8 by Jonathan MacDonald, on FlickrĭSCF1051a Sigma 28mm 2.8 by Jonathan MacDonald, on FlickrĭSCF1037a Sigma 28mm 2.8 by Jonathan MacDonald, on FlickrĬhromatic Aberration, soft sides and corners For most people looking to try an old 28mm lens this Sigma would be my recommendation. In fact, the only classic 28mm lenses I've tried that I like more are the K and Vivitar (both Komine and Kiron) 28mm f/2s, which cost much more and are much harder to find. It's far superior to the Pentax M series 28mm f/2.8 or /3.5 and compared to the A series 28/2.8, which it would have competed with back in the day, it's much sharper and has much nicer bokeh. The close-focusing capability of this lens is extremely useful and makes it a good lens for capturing little details.Īll in all I'm very happy with the lens, especially for what it cost. I opened the lens up and removed the pin (rendering the A setting useless regardless of the camera used) for safety. My copy has an A setting on the aperture ring but it's not compatible with Pentax's implementation of automatic aperture, it's compatible with Ricoh's system which means it has the dreaded Ricoh pin which can cause the lens to get stuck on an AF K-mount camera. Perhaps if you used this as a general use wide angle on FF or film then the sun and other light sources would be more problematic. Many reviews warn of flare but it's not something I've experienced a great deal and when I have I've been able to control it and use it to add to the image rather than detract from it. Image quality is very good, with nice colour rendering, good contrast, nice out-of-focus rendering and it's very sharp even wide open. It handles well and is a pleasure to use on both DSLRs and mirrorless cameras. It's light but still made of metal and compact. This little Sigma must have been very close to the top of the pile because it's an excellent little lens that can be had for very little. Not as well-built as an M series, flare, many copies are for Ricoh cameras and have the dreaded Ricoh pinīack in the day there was fierce competition to provide wide (28mm) and telephoto (135mm) primes for people to add to the standard 50mm lens that came with the camera. Small, light, good rendering, very sharp even wide open, nice bokeh, very useful close focusing Sadly, because of the shortfalls, this is not a lens I could recommend if you can afford a Pentax M 28mm as it's a much better lens in every regard. I ended up finding a Pentax M SMC 28mm that wasn't asking silly price. And if you don't venture to taking images of focus beyond 30 yards, its a good lens. As it's not fashionable and supertrendy like Takumar or Pentax M or A lens of the same mm you can pick these up for a fraction of the hyped up price of those brands. On film cameras, this lens is left looking rather ordinary beyond about 30 yards of subject focus. With some shots this can be fiddled around with in digital software (yes, those editing things few people ever openly admit to relying upon) or onboard camera digital presets. Mine got rather disappointing at full infinity, with a lot of centre and edge fuzzy softness. This can lead to some nice atmospheric images. But things get a bit soft around the edges at times and some shots start to look shaky as you approach infinity. You'll get a good and fairly neat image in the centre and a bit of fuzz around the edges at most of the usual f5.6 to f11 "sweet spot" range. Mine came with what looks like Pentax A series mount connectors. The symbols are not painted into fully depressed engravings, so they wear off in time. The turn is solid, but there is a bit of plastic feel to it. Very fine close focus ability that gives clear and sharp results. Focus from 4 inches to infinity is impressive. A fairly nice and fairly well-made 28mm lens. ![]() I had an optically mint condition lens for a couple of years.
