The 1.4 EX DG is placed between the lens and the camera, and it allows the photographer to use the 70-200mm f/2.8 lens as a 98-280m f/4 lens, and the 300mm f/2.8 lens as a 420mm f/4 lens; the high optical performance is maintained and the AF speed is not affected. More

Amazing little gem!

About Me Semi-Professional
I shall keep this short and sweet. The Sigma 70-200mm f2.8 is great enough. When this is on the end of it, even more of a result. It gives you 280mm, and yes ok, the f-stop goes down to f4, but there is no drop in performance that i have noticed. So brilliant!

Best independent converter you can buy
Sigma again show they are a serious lens manufacturer by making this beautifully engineered, (made in Japan) constructed and finished teleconverter, for all us out there who aspire to own and use dream Nikon super lenses - but cannot afford them.That's the philosophy behind their best lenses and with my full-frame Nikon D700, this brings 'it' in line with the DX format. With the 70-200mm f2.8 Apo I use a great deal, for bands, low light events etc. the 1.4 brings it up to a 100-280 f4, which is still faster than my normal 70-300mm zoom. The camera's display shows the amended, working aperture and the metadata is altered accordingly. The HSM AF still works brilliantly. It is perfectly matched, both physically and optically.I've tried it with my 150-500mm and Sigma say it is compatible (displays amended, as with 70-200) but AF doesn't even operate. Manually focussing an effective f9 is no joke and almost impossible, due to the dark viewfinder and the OS is seriously affected. You will have a real challenge getting a sharp shot. Best to either crop or (in my case) use my D200.I am pleased that it is surprisingly useful and well performing with new Tamron's SP 70-300mm (their flagship model), even at 300mm. Centre definition is almost as good as without it, though edges and corners less so, but that's fine for sports and wildlife where the subject is in the centre. An effective 140-540mm focal length with the D200 brings it up into the realms of my 150-500mm megazoom, without the bulk and weight, though it has to said, the Sigma at those lengths on its own will always be superior.Photographers specialising in these genres are the most likely to buy a quality teleconverter and for whom I cannot recommend this product highly enough. It puts faith back into serious photography and its equipment. Pricey, but gems are, aren't they?

Not as good as I thought
One of the features that was not made clear was that in some brands of cameras the converter was manual focus only. I have been disappointed therefore with the value of this product as a result. It works but it is slow.
Bottom Line No, I would not recommend this to a friend

A very good buy
from Greater London
The product is well made and fits tightly to both the camera body and the lens. With a bit of practice it is possible to attach and detach the teleconverter quickly but you must organise yourself beforehand with pouches and bag.The autofocus function and autometering continues to work with a Sigma 300mm prime lens with no noticeable loss of speed.For example, with a DX format camera such as the D300 with a times 1.5 factor the 300mm lens becomes and 450mm lens. Adding the teleconverter increases this to a 630mm lens. The loss of image resolution is minimal and the increase in general length of the total assembly is barely noticeable. It is still possible to handhold the camera on a sunny day at f/4.5 at ISO 400. Using a x2 teleconverter will require a monopod or a tripod unless your technique and/or upper body strength is above average and increases the lens length considerably.I have tried using teleconverters with zoom lenses (50-500mm) and the results are rather disappointing as the trade-off of increase in magnification is negated by the poor image quality especially at long range and high magnification which is when you need it the most. I would recommend using this and the Sigma x2 teleconverter with prime lenses only as the optical components are compatible.Overall I consider it a valuable addition to the camera bag. As with any teleconverter, it is a cheaper way of increasing lens magnification rather than buying a 400mm or 600mm lens.
