Doesn't work very well with auto focus.

Let me begin please with my 3 stars reason: 5 stars would be elation, 4 stars would be "if I kept it" , so 3 stars it is. I would recommend this for particular reasons not a blanket to everyone. I'm only semi-pro because 1)you don't know me 2) I don't make enough on my stuff to do taxes on it (although I probably should next year) 3) sometimes I'd rather hire someone else to do my bidding... but that's how I am in music production too and I do that well. Call me a psychic but you don't want to spend for the $ dollars 2x Tele instead of a new (give or take $) lens - or you want to consolidate your weight in extra reach lenses when traveling or on a shoot. Check mark all of the above for me. My first experience was attaching it to (everyone together now) Canon L 70-200mm F2.8 IS ...with Canon Crop 60D Body (do the math for zoom). I like taking this body in places I won't have a heart attack over if it breaks and actually would be where I'd use the teleconverter in distant - subject outdoors shots. 1st tests were on still subjects indoors with good light, and resolve was very impressive at overall glance. Zoom in on viewfinder and there was a nice CA (as in noticeable) around the clear glass vase. Detail of object was good but when there are hard angles (and yes I was giving this little devil the super test against light and glass) you must be SUPER fast on your shutter at say... 2500 it was closed down pretty well but for prints, just make sure you do a little post ... the bokeh was preserved of the flowers outdoors (roughly 200M away) and was slightly obscured but acceptable (the slight drag pull instead of perfect round bokeh). Next was to shoot from indoors to outdoors across the street, through a lot, across the next street to moving subjects, with a total distance of about 500ft. This was a sunny day. Without tele, the cyclist riding up the street looked like he did... slapped the tele on and all of the things I couldn't make out sprang to life - this was a profile against greys and greens. the crop zoom would show the slight again CA smear but as an image, it was VERY useable. I thought this sort of distance and light was really good but it still was "through the looking glass" look to me and I'm super-detail oriented. Next I shot about 1/2 mile away at subjects and it was still impressive but the detail was really more academically okay, the energy of the subjects were not really there- it's hard to describe when something changes something but this was a VERY challenging shot that involved many blues and greens since there was water, trees, surfers, and not bright. Nevertheless I'm always shooting with 100ISO for least noise in my tests. Now, with these experiences I would alone have kept the item. If you're going to slap this only on the 70-200 type lens with F2.8 native, then go and get it, if you need to "sell" the closeup you need to be able to hit it with some post processing and all of you can do the bare minimum I'm assuming, if not, then you still will like the tele because you can't tell the difference anyway. Using on the 24-70mm F2.8 L I had a different experience: Shooting more than 20 miles away from the channel islands from a 2990ft peak I could really bring them all together up close and was dazzled by the shot, but I still felt like there was that "filter" of clarity - still useable though, this is the funny part I would say you could have framed it still and blown away most people.So why did I return it? The deal breaker was when I zoomed into my female subject that was about 3-400 feet away and on later inspection, frankly I couldn't tell who she was because of the details that make her "her" were not there. White sweatshirt had haze between body parts, face was not there, the blurry focus was unique to this combination and I would have loved to have the 70-200 for comparison, but a 24-70 L glass with all of the correct settings (yes I cranked up the everything and really shot cool and calm with multiple shots) should have given me some more resolve in these images of "person against big rock with good afternoon sunshine... " perhaps the golden-ness of the sun was a combo this glass didn't favor, but it certainly has a sweet spot and I must urge you to answer your own $100 question. Because I know even the most scrutinizing pro that reads this will agree when they see the results that it's a tool that can be used in a pinch in critical moments. However, I want only one tele converter and it will be the canon model likely. Go try it, for [$] you really cannot afford NOT to try it.

Not a product that I would recommend to anyone looking for a quality addition to any lens. This 2x converter is mediocre at best. I'm quite disappointed with the purchase. I should've paid more to get something a bit better.

As a hobbyist this is a great help when that great shot is a little to far.

I'm using this with a Canon XSI and Tamron 18-200 lens. Autofocus is fast and very sharp. Surprised me that it was so easy and no adjustments to my camera was needed. It's a bit longer now and doesn't fit in my case if I leave it on so will have to rework my carry case. No major issue there. It dropped me a couple stops of light but the camera understood it and I'm still getting nice images which is what's important to me. I try and run higher f-stops for sharper images anyway so it was no loss for me. Overall with my setup I like it. Very good for the price.

I have a canon Xsi and so far have only used the converter w/ a Sigma 70-300mm APO lens. I really does reach out there, but the manual focus w/ THAT lens is hard because it's not very tight. I'm going to have to practice quite a bit. Best shots so far have been w/ a Fstop of 10 or higher to combat the lack of precise focus on my part. I'm hoping it will work a bit better w/ my Tamron 90mm macro.

Great extender of range for my lenses. I do need to tape the contacts on my camera to disable the autofocus features when using my Pro-Optic 500 mm lens as a 1000 mm lens. The camera will not take a picture otherwise. This is not really a problem though.

brings things close, but focus is not the greatest, sometimes it's "hit or miss". the best thing about digital photography is you can shoot "lots" and pick the best ones.

I had been using a Olympus 570UZ with a 20X Zoom. I am now using a Canon SXI with a 70-300usm,is lens which falls short. I bought the 2X tele converter hoping to close the gap, but it didn't make it. The converter is fine I was just praying for a miracle.

It did the job of bringing in the distant image but required manual focusing and that is a drawback when shooting a subject in motion that changes distance from the camera.

For the money this is a great converter. I use it with my Canon 70-200f/2.8L lens and get great results. I have the Canon 1.4 converter and notice only slightly better quality with the Canon product than this converter. This converter was a great addition to my telephotos, making my 70-200 essentially a 140-400 on my Canon cameras. Unless you need absolutely the best image quality you can possibly get this converter will be fine for all your needs. Autofocus was still fast and accurate using the converter, with only slightly noticeable lag compared with the lens alone. I would recommend this to anyone looking for an affordable converter to add to your lenses.

bought this for getting in those long shots - And boy did we use it on my canon 70-300 at the inaururation ceremony of our 44th President. It does exactlyas advertised. Had a great time at the cermonial ball.
