Sigma is introducing two native AF lenses for both Micro Four Thirds and the Sony NEX mount.
Both lenses are part of the Sigma EX range of high quality lenses and part of a new range they are calling DN – Digital Neo.
First up is a 19mm f/2.8 prime which Sigma describe as being ultra compact and weighing only 4.9oz with a linear AF motor for silent and fast auto focusing. For more information, check out the Sigma website here – http://www.sigmaphoto.com/shop/19mm-f28-ex-dn?link=jan_m_1_cta1
The second lens is a 30mm f/2.8 prime, again described as an ultra compact lightweight lens, featuring the same silent AF motor. More information can be found here at the Sigma website – http://www.sigmaphoto.com/shop/30mm-f28-ex-dn?link=jan_m_1_cta2
Whilst it’s great to see lenses coming through for both M43 and the NEX systems, personally I can’t see the point of these focal lengths on either system – my main interest would be for the NEX as there is a serious lack of decent lenses for that system, but I already have the Sony 30mm NEX macro lens, which is pretty sharp and only a half stop slower, plus it has 1:1 macro.
The 19mm makes an approximate 27mm equivalent on the NEX, which isn’t wide enough for me to consider it a wide angle lens and isn’t long enough to be useful as an every day lens as people are not going to be portraid in a very flattering way. I suppose in M43, 38mm may make more sense as a carry around street lens. What I’d really like to see is a 60mm 1.8 for portraits on the NEX as it is sorely lacking anything around there, and a nice sharp 16mm (or wider) prime for landscape shots as the Sony 16mm isn’t all that great.
Pricing hasn’t yet been announced, but I’d expect given that it is Sigma for prices to be competitive.
