Originally posted by Cynog Ap Brychan With all the experience that members of this forum have, can anyone recommend any MFT zooms covering wide to normal, and telephoto (two lenses, not a superzoom) that are small and light, but really good optically?
Basically, the philosophy of both Olympus and Panasonic seem to be that high end zooms require fast apertures, and therefore must be (relatively) large and heavy, and that slow aperture zooms are essentially budget lenses, and therefore must be, optically, consumer-grade. So, for the most part, compact m43 lenses are consumer grade in quality. The high end zooms are bigger, heavier, and not so compact. The one exception is the Olympu 9-18, which, while it isn't quite as sharp as a pro-level zoom (particularly toward the edges and corners) nonetheless has the contrast and color rendition of high-end glass, and is capable of producing images that look as good as what you can get from the 12-40 or the primes. With the exception of the pancake zooms, I've shot with most of the m43 compact standard zooms, and I don't think any of them are significantly better than the others. They're very good for consumer grade glass (better, IMO, than the DA 18-55); but they are not in the same league as the m43 primes, the Oly 9-18, or the pro zooms. The Panasonic 14-45 often is regarded as the best of the lot, because of it's consistency across the zoom range (it's decently sharp edge to edge throughout the zoom range), and because it's performed fairly well on numerical tests. But I preferred what I saw coming out of the Oly 12-50. I never could completely reconcile myself to the color rendition of that 14-45, and I also found it prone to veiling flare. These are all consumer grade zooms, and as such, regardless of how sharp they may be, they're not going to produce images that have the richness and "pop" you get from top-tier glass.
I've only shot with two of the compact telephoto zooms: the Oly 40-150 and the Panny 45-150. Both are very good for consumer grade lenses. The Oly is fairly sharp from 40 to 80mm, and retains decent resolution all the way to 120mm. I'm less familiar with the Panny lens, but it seems to have the same sharpness as the Oly, but slightly better contrast.
