| comment: | This is the lens the Sony G primes pretend to be. It also remind me of Sigma's older 30mm F2.8 DG Art. Thankfully the brushed aluminum of the later has been exchanged for a more durable anodized texture. It does resemble inexpensive C-mount lenses, but Sigma has probably used a good amount of more appropriate materials. This lens was launched at a retail price of $550, but has been steadily discounted. "MADE IN JAPAN" The angle-of-view is just slightly tighter than the Pentax-FA 43mm F1.9 Limited. The 40 mm primes are all wider. The other 45 mm primes are much narrower. It seems higher quality than most other lenses. The front plastic trim was carried over from their APS-C primes, but the lettering is now just painted instead of engraved. The aperture ring markings are engraved and painted. The filter thread and hood bayonet on the lens are metal. The matching bayonet on the metal hood uses a chunky plastic insert. I would have prefered a monoblock composite lined hood which didn't interfere as much with manual focus. The hood somewhat blocks the focus control when installed. Don't plan on using both together. Sigma prioritizes aperture control over manual focus. The "A" setting of the aperture control has enough resistance to not be much of a nuisance. The third stop detents are nicely spaced. Third-stops are excessive, but Sigma is merely following Sony with this. It feels nicer to use than the mechanical linkages I've used. This lens is marketed by Sigma for its rendering. This is accomplished by a high amount of under corrected spherical aberration. This causes out-of-focus foregrounds to be rather rough and hard edges at close focus show a good deal of neutral fringing. The Sony FE 50 F1.8 is also somewhat under corrected for SA but is much sharper close up and renders foregrounds much smoother. The Sony doesn't match the clarity of the Sigma within the depth-of-field. I was surprised to see that backgrounds can sometimes be a bit busy with the Sigma. Autofocus is much improved compared to previous Sigma DN lenses I've had. The AF motor is somewhat audible and its motions can be felt, which is somewhat surprising in such a small, solid feeling lens. But the element(s) move quickly. |
