The Opteka 650-1300mm high definition manual focus super telephoto zoom lens is perfect for the professional and amateur photographer alike. Using a 2x tele-converter with a 650-1300mm lens will effectively increase the focal length to 1300-2600mm. A lens set to f/8 will now be f/16. There is a built-in, rotating tripod mount for easily attaching to your tripod or monopod. It’s an extremely powerful telephoto zoom lens with the versatility that you need. This lens is great for the wildlife or nature photographer who wants to be hidden while taking photos of the subject. When combined with the included T-mount to fit your camera system, this super telephoto works on both “full frame” cameras as well as the “APS-C” style digital SLR cameras. You can use the lens in “M” manual exposure mode or “A” aperture-priority mode only.

Advances in ultra high-index / low-dispersion optical glasses, new barrel materials, and exotic anti-reflection coatings, along with the latest in computer-aided-design / computer-aided-manufacturing, are combined to produce lenses of unprecedented quality. Diamond-cut from crystal-clear, water-white optical glass, Opteka lenses are ground and polished to a precise precision. This puts more creative control where it belongs, in your hands.

Bright sunlight and a sturdy tripod is recommend when using this lens.

I got what I paid for. Well, all I have to say is that I got what I paid for. I spent a long time researching this lens and read a lot of negative reviews about it, but decided what the hell and got it. There are a few things to keep in mind with this lens: There are NO other lenses produced for this focal range (650-2600 [with teleconverter]), so it’s absolutely incredible at pulling in objects from a long distance. However, there IS a reason why manufacturers /don/’t make such lenses – it becomes VERY difficult to reduce aberrations at such specifications.At 650mm f/8, the lens is…decent. It’s a fair distance to zoom, and f/8 isn’t that dark. The bokeh looks pretty nice. However, at longer focal lengths (1300mm, 2600mm), there is some serious chromatic aberration. Colour fringing is to be expected, and image sharpness/quality is seriously degraded beyond 1300mm. Also, at that point, you’re shooting at apertures of f/16 and above, the smallest being f/32. Which brings me to another…

Happier then expected I’ve been reading mixed reviews on the Opteks lens for a while, for the price I thought I take a chance. It performs as expected. The zoom mechanism is a tube near the camera that slides, it’s not smooth and a little clunky to do, but it works. I don’t use the double much, don’t really need it, and it does not fit in the bag with it attached to the lens (I think this is a flaw and the bag should have been larger) and there is no separate bag for the doubler – rather then take the chance of dust getting in the lens from screwing and unscrewing the adapter from the lens then attaching the doubler and screwing back on the adapter to the doubler, I just don’t use it much. You have to take your time on focusing as it is very sensitive. You are able to handhold it at 650mm (just bearly) but at any other zoom level you must have a good tripod to hold it. This lens is HUGE. I would recommend this lens for nature or senic photography, but it’s not fast enough (f8-f16) to use if for any…

Opteka 650-1300mm (2600mm with 2.0x teleconverter) on APS-C body review. MY LIFE AND THE OPTEKA 650-2600mm ON NIKON DX ( APS-C )…. UPDATED 7/4/2016Here’s a review for crop-sensor folks. All comments below are my tests (and results) with a D7100 and D5500 – Nikon DX (APS-C). First off – this lens is a manual focus lens. If you use AUTO on your DSLR mostly – this is probably not for you. Unless you want to learn how to manually focus a monster like this. I bought this lens for the reach to price ratio.NEW GOTCHA – UV HAZE FILTER — REMOVE ITAfter writing the review I decided to go back and re-test the lens. After taking several test shots, I was surprised at the lack of sharpness compared to what I’d previously experienced. The only equipment change was the addition of a UV Haze filter – it significantly reduced the sharpness. I removed it, and re-tested and found the lens to be decently sharp as stated below. I was surprised how negatively it impacted sharpness.OTHER NEW GOTCHA – OPTEKA T MOUNT ADAPTER…
