There's no doubt in my mind that the Sony SEL2470GM2 lens is a can buy. The second version of Sony's zoom lens is lighter than the first, and still packs the great optics of a GM lens. It's a great all-around lens, and professionals will want this. But casual consumers like me will baulk at the S$2,999 price — unless you need the best performance possible.
- Filter diameter: 82mm
- Minimal focus distance of 0.21(W) – 0.3(T)m
- 20-element lens
- Angle of view at 35mm: 84°- 34°
While the SEL2470GM2 claims the title of the lightest F2.8 zoom lens at 695g, my Tamron 28-75mm is lighter at 550g. However, this is not an apples-to-apples comparison. The SEL2470GM2 is definitely lighter than its first incarnation, though. I like that the lens comes with various dials that aren't on my Tamron. You can set the aperture manually, whether it clicks when you do so, the tightness of the zoom ring, manual or autofocus, and a focus hold button. The Tamron, in comparison, lacks any buttons.
I do like having these options, though. The tighter zoom ring helps keeps your settings in place, and you don't accidentally change it. Being able to adjust the aperture manually is nice, but I don't think it's necessary since it's a lot quicker to use my camera's own controls. The focus hold is nice, and frees up your right hand to do other things such as adjust ISO or exposure.
The performance of the Sony lens shines, with sharp corners at all focal ranges. Even at the widest aperture of F2.8, things at the sides look clear and sharp. This is one really good lens. Bokeh is creamy, and I love how it looks. You also get the neat starburst for lights that's typical in a GM lens. Autofocus is also quick, too. See above for our test shots.
At S$2,999, the Sony SEL2470GM2 isn't cheap. But it offers superb image quality for those that want only the best. That said, the much cheaper S$1,288 Tamron 28-75mm is a great buy for those who want good image performance without breaking the bank. Get the Sony from Lazada or Shopee.
