My summary of the Tamron's 20 mm f/2.8 Di III OSD M 1:2 test was hardly enthusiastic but in the case of the 2.8/24 model I admit I am far more optimistic. The 2.8/24 lens is noticeably sharper in the centre and on its edges – here you really can't find any weaknesses. What's more, it compares favourably with its direct rivals, both the cheaper one (the Samyang AF 24 mm f/2.8 FE) and also the noticeably more expensive (the Zeiss Batis 2/25). It seems there are a lot of reasons for buing this lens, especially that two of its flaws (distortion and vignetting) are quite predictable for this kind of equipment. The only thing that really bothered me was slow autofocus. If it performed a bit better I would recommend that lens without any doubts or second thoughts.
