I have always held a negative impression of teleconverter, thinking that it would seriously and negatively affect the optical performance of any lens attached to it. Someone in a photo discussion forum brought up this TC and showed a few pictures that were indeed quite impressive. I am not a big fan on long lenses but there have been situations where longer focal length was needed. A good quality TC would have been handy. After looking at the price, I gave it a try.Matching with a Tamron 70-200, center sharpness was excellent while corner was degraded a little. There was a slight but noticeable drop in contrast which can be recovered easily in Lightroom. Stopping down the aperture helped to bring IQ up across the entire frame to just shy of excellent. This is the combo that will be in my bag from now on. Moving up the FL of the primary lens, I was expecting disastrous results when matching this TC with a Sigma 100-300 since Sigma has a matching TC at 3X the price. On the contrary, the combination was even better than the Tamron 70-200 combo. I did not notice any degradation in sharpness or contrast. May be it should not be a surprise as the Sigma 100-300 is such a fine lens. I just realized that I have effectively bought a fantastic 600mm f/5.6 (on APS-c) for $96!!!!! Would the matching Sigma TC be even better ......Elimination of vibration and hand shake is key to getting good results for long focal length. Make sure you have a sturdy support when you do the evaluation. I also did my evaluation with mirror locked up, a shutter release cord and a 2 second delay. Just behind the Samyang 14mm f/2.8, this is the next best value I acquired so far.

I bought this TC last year after reading some good reviews. It's basically a sub Tamron 1.4x TC which is discontinued and pretty expensive to get a used one on ebay or whatever used market. Anyway, I thought it's under 100 bucks, why not give it a try. It turned out to work pretty well with my DAL 55-300mm. The trick to get faster auto focus is that you need make the lens wide open, and get focus at 55mm first (since aperture is 4, it's pretty fast), then zoom in to 300mm, then focus again. This trick works for me pretty well most of the time. Of course light condition is still the key for the speed. The IQ is not perfect but very acceptable if you nail the focus and shutter speed is fast enough. I would say this combo is solution for people on budget who want to get more reach.I purchased DA 1.7x AFA later, the result is even better, but it's used and very expensive. It's another story...Hope this helps, good luck!

Paired this with my 55-300mm Pentax telephoto. I expected the worst but got nice clear shots at F8 from 40 ft of a golden Sparrow in a tree . When using with a Tamron 90mm f2.8 1:1 macro lens I noticed a little purple fringe between light objects close together at high magnification in photoshop but couldn't see it in 5 x7" prints. It is definitely worth the low price compared to other makes offered by bigger name manufacturers. Definitely have to use a tripod as even your heartbeat will blur the picture at 300mm+1.5 sensor crop factor+1.5x tele-converter.
