Competition

As already mentioned in the introduction, there are a couple of alternatives to the Sony E 70-350mm f/4.5-6.3 G OSS (shown to the left below). There are its in-house cousins - Sony FE 70-300mm f/4.5-5.6 G OSS (center left) and the FE 100-400mm f/4.5-5.6 GM OSS (right) - as well as the brand new Sigma 100-400mm f/5-6.3 DN DG OS (center right). Sony cameras are already very small but this is especially true for their APS-C versions. Just in terms of balance, the E 70-350mm f/4.5-6.3 G OSS is more enjoyable to use. Performance-wise, it's roughly comparable to the Sony FE 70-300mm f/4.5-5.6 G OSS while offering a little extra in terms of reach. It also has a slightly faster AF. The FE 100-400mm f/4.5-5.6 GM OSS is surely better still but it comes with an outlandish price-tag that will be a showstopper for most users. The new Sigma lens is within the same price realm and it seems to be impressively sharp but may suffer from an inferior image stabilizer (yet to be tested).

Verdict

Generally, we were quite pleased with the Sony E 70-350mm f/4.5-6.3 G OSS although it's also clear that Sony had to accept some compromises in order to achieve the compact dimensions. The sharpness is very high between 70mm and 250mm but there is a more pronounced drop in quality at 350mm. It's not bad at all but you will see a difference there. The amount of pincushion distortions is a bit over the top in RAW files and there's also significant vignetting (for an APS-C lens) at maximum aperture. Thus it's a good idea to leave image auto-correction activated to handle this issue - and it does so flawlessly. As far as the quality of the bokeh is concerned - out of focus highlights are a bit on the rough side although it's fair to say that this is rather typical for long tele zoom lenses. It's still one of those areas where prime lenses outshine zoom lenses by quite a margin. However, the general bokeh is pretty smooth in the image background at least.

The build quality is on a high level and comparable to other G-class lenses that we tested so far. It feels sturdy thanks to high quality materials and smooth control rings. It also features a dust and moisture resistant design. The AF speed is good for such a lens. The image stabilizer comes handy because most of today's APS-C Sony cameras do not offer a built-in stabilizer yet. Based on what we have seen, it can give you a gain equivalent to 3-4 f-stops.

Overall, the Sony E 70-350mm f/4.5-6.3 G OSS is a interesting option for those who prefer to keep the overall size & weight of their setup down to a minimum - after all this was one of the core ideas of the mirrorless paradigm. The price tag may be a bit steep but it's not too far off considering the optical and mechanical qualities.
