Minolta AF 20mm f/2.8

(8 customer reviews)

The Minolta AF 20mm f/2.8 is a camera glass that provides a wide angle view for full frame cameras. It has a bright aperture value and 7 aperture blades, which provide a decent bokeh effect. The lens is lightweight, weighing 285 grams, and has a 72mm filter diameter. Its length is 53mm, so it is easy to carry around. The lens has an auto focus feature and can also be manually focused. It is made up of several lens elements that provide excellent resolution. The lens has a coating that protects it from scratches and other damages. The lens was manufactured in the past, so it may not be available in the market. However, there are alternatives available that provide similar features. The build quality of the lens is good and it can last for a long time if taken care of properly.

– Good build quality with a solid feel and weight to it
– Fast f/2.8 aperture, which is great for low-light photography
– Good sharpness in the center of the frame, even at wider apertures
– Nice, wide field of view for landscape and architectural photography
– Autofocus is speedy and accurate

– The lens sold to me was not as described – it had light scratches on the front glass and an obvious dent on the filter ring
– Sharpness falls off significantly towards the edges of the frame
– Distortion is present, but can be corrected in post-processing
– Chromatic aberration is noticeable in high contrast areas

Overall, the Minolta AF 20mm f/2.8 is a decent lens with some caveats. While it has good build quality and a fast aperture, buyers should be wary of getting a lens with scratches or dents, as this can affect image quality. Additionally, the lens’s sharpness and distortion issues may be limiting for some photographers. Nonetheless, it’s a good lens for those who need a wide angle of view and don’t mind post-processing to correct issues.

Optical design

Bright lens thanks to the high aperture value Has 7 aperture blades, mid-grade lenses usually have this amount of blades. Having rounded blades provides out of focus circle shape closer to a circle.

    Great lens for full framers If you use a full frame digital camera, you know finding a wide angle lens with greater field of view than 24mm can be difficult and expensive. For Sony a mount users (a99 for example) this lens is a dream come true. It is pretty much the same as the Sony version, but if you look you can find the Maxxum version for lower price.

    I have only used this lens a few times, but it does a very good job. I like to shoot in aperature priority and stay around f8 or f5.6 whenever I can. The images are pretty good even wide open at f2.8. They are even better at f5.6

    Get one while they are still available. I am stocking up lenses, as the new SONY A55 is so convincing, that I will replace the NIKON D700 as a Full frame DSLR with the A900 to be able to shoot A-mount lenses in 2 different focal length, which means 20mm on the A900 and 30mm on the A55. So far I used a 20mm SIGMA 1.8 on the D700, as Super Wide Angle and also for available light, with good results.
    The Minolta 20mm 2.8 is mechanically as solid as any Minolta lens of that aera, and the colors are unsurpassed minolta like. The lens is prone to flare (as all Minolta wideangles), distortion and vignetting, but that is in the nature of a wideangle lens. Highly recommended for an A850/900 (20mm), good on APSC A-mount Sonys (30mm). The new SONY 20mm f/2.8 seems just to be a rebranded Version of the original Minolta lens, and with 560.00$ street it is double the price…

    Sharp with classic Minolta colors A good lens for a full-frame Sony shooter, is well suited to nice and wide landscape or night sky imagery. A bit soft in the corners wide open, but stopped down to f/8 its extra crispy across full frame – recommended!

    Very good lens, sharp enough, minimal distortion Great lens, minimal distortion compared to other 20mm lens, AF works good and if manual focus is used, you can easily focus to infinity by just turning the focus ring to an end. Apertures 2.8 and 3.2 not so good, but starting from 4.0 till 11, it’s all surprisingly sharp.
