This review is from: Opteka 500mm / 1000mm High Definition Mirror Telephoto Lens for Pentax K-30, K-2, K-M, K-5, K-R, K-X, K-7, K-2000, K20D, K100D, K110D, K10D and 645D Digital SLR Cameras (Camera)
Being an optical systems designer by training, with some of the finest glass on the market in my inventory (including the past purchase of a $70K aerial lens), I was amazed by the quality and capabilities of this reflection based 500mm T-mount lens. When shipped through an Amazon reseller, the package included a 2x teleconverter and a T-K mount Pentax adapter. An important consideration behind this lens is that it is a fixed aperature (f/8 with supplied 2d (f/16) and 4d (f/32) neutral density filters). I found this lens to be worth ever dollar of the original $400.oo list price, instead of the very attractive package that Amazon put together. Having worked with other reflector based tele lenses and telescopes, including Celestron optics which I am very familiar with, I found this lens to be at the top of it's class. Along with it's solid metal construction and light weight, this lens also surprised me by it's macro capabilities, focusing down to about 5', amazing for a 500mm... Read more

This review is from: Opteka 500mm / 1000mm High Definition Mirror Telephoto Lens for Pentax K-30, K-2, K-M, K-5, K-R, K-X, K-7, K-2000, K20D, K100D, K110D, K10D and 645D Digital SLR Cameras (Camera)
I have on two occasions in full sunlight taken long distance shots (10 yds to 75 yds) with this lens on a Pentax K10D (around 30 shots). I was not ever able to get a picture in focus and it is not a depth of field issue---the whole picture was blurry. All shots were taken with the camera on a tripod and with 2 second delay. At the same time I took the pictures with my Tamron 28-300 on the same camera body and tripod set up. All the shots at 300MM cropped looked considerably better than anything shot with the Opteka 500MM. I would not recommend this lens to anybody. A lens that doesn't produce clear pictures is not worth any price. (Maybe the issue is the K10D plus lens combination. There is no way for me to check that variable.)

I've never heard of Opteka before I bought this lens, but I said why not try it? And I'm quite happy with it. I did not have the time to thoroughly test it but for the first looks it quite ok. I use it with a Pentax K-x.
Pros: - good focus range - 2x tele converter and 3 filters - decent size good handling - despite its big focal lenght good close focusing (less then 2m!)
slight Cons: - requires a lot of light (fixed f/8) - but open doors there's almost always enough sunlight. - manual focus only - can be advantage as well - but can be hard when not enough light.
Over all it's not the best lens, but for a hundred bucks it's quite good. Also it requires some experience to take good pics with it, because even if you see the image in the viewfinder bright it still might produce underexposed pics. Ergo use manual shutter speed. Glass and lens quality is fine for this price.

The Sigma APO 50-500mm F4.5-6.3 DG OS HSM is a 10x high zoom ratio ultra telephoto zoom lens incorporating Sigma's original Optical Stabilizer function. This lens covers a wide range of focal lengths from 50mm to 500mm ultra telephoto. The OS (Optical Stabilizer) function offers the use of shutter speeds approximately 4 stops slower than would otherwise be possible. For Sony and Pentax mount, the built-in OS function of this lens can be used even if the camera body is equipped with an image sensor shift anti-shake system.As compensation for camera shake is visible in the view finder, the photographer can easily check for accurate focus and ensure there is no subject movement. Four SLD (Special Low Dispersion) glass elements provide excellent correction of color aberration. The Super Multi-Layer Coating reduces flare and ghost and ensures high image quality throughout the entire zoom range. This lens has a maximum magnification ratio of 1:3.1 (at the focal length of 200mm) making it ideal for close-up photography. It incorporates HSM (Hyper Sonic Motor), ensuring quiet and high speed AF as well as full-time manual focus capability. The addition of the optional 1.4x EX DG or 2x EX DG APO Tele Converters produce a 70-700mm F6.3-8 or a 100-1000mm F9-12.6 MF zoom lens respectively. This lens is equipped with a Petal-type hood to block out extraneous light. The filter size of this lens is 95mm and the lens is supplied with a step down ring enabling digital cameras with an APS-C size image sensor to use an 86mm filter.

Just received the lens. Using with a Cannon EOS XTi.
Pros - Sturdy feel to the lens - Impressive focal length range. - Good picture quality throughout the range (speaking as a non-pro) - OS pretty good. Taking acceptable quality hand-held shots at full extension in bright sun.
Cons - Autofocus not working out-of-the-box. Of note that this lens was NOT in the serial number range specified by SIGMA's customer alert. - Very poor response time on queries to SIGMA's tech service. - Some (minor) vignetting noticable at longer focal lengths. - Does not work with my TAMRON teleconverter even though this TC does function with my Cannon lens. - Heavy
Returning the lense for replacement through AMAZON due to the autofocus issue. Will see how well the next one does.
UPDATE: Received replacement lense from AMAZON with working autofocus. Took it out today for extensive testing and am well... Read more

I've had this lens for a few days and am very pleased with it. Given the fact that it's covering such a wide range, I didn't expect it to have very high IQ, yet I am pleasantly surprised. I measured it against my super sharp Nikon 70-200mm f/2.8 VRII with TC-17, both @ 340mm f/6.3 and f/8, and the IQ is about the same on a D300s, even though on a full frame D3s, the 70-200mm + TC-17 is slightly sharper. This is quite remarkable, because 70-200 f/2.8 VRII is one of the best lenses Nikon has ever made, and it can produce better pictures at 100mm than the highly regarded Tokina 100mm macro lens I own, and even when shooting macros, the 70-200 + TC-17 + Canon 500D combo is comparable to the Tokina 100mm.
Image color is great, with vivid contrast. I had a few bird shots at fully extended 500mm and they turned out to be great pictures. CA is minimum too, only slightly visible when fully zoomed in, and no worse than my 70-200+1.7 combo. Focus is fast, even though it has always... Read more

Rented this lens for my son and nikon 500mm f4 for myself for yellowstone photo vacation. Honestly the 50-500 was considerably more useful. OS seemed to be better or at least equal to nikon vr, only slightly less sharp, contrast and colors are also very good. Size difference is huge and he was able to get shots before i could manuver the huge nikon lens. Autofocus was snappy and acurate, he was able to get spot on pictures of golden eagles at 500mm in flight free hand held. I grabbed his camera to jump into a riverbottom and get pictures of a bull moose, that's when i realized just how good this lens seems to be. 6.3 is a little dim but with ISO performance getting better less of an issue. I've always had issues with non-nikon lenses hunting but didn't experience it or at least it was small enough it didn't leave an impression. Distortion seems aceptable and after i review the photos a bit i will likely purchase one.
