    Learn to Use It - Great Tool
  

*by L***S on Reviewed in the United States on June 2, 2021*

This is great BUT you have to learn the tool.  My experience with these teleconverters is via a Nikon D7500 and the Sigma 150-600c telephoto.Numerous people will trash talk the teleconverters and I myself bought the TC-1401 first and didn't like it.  I didn't understand some fundamentals of photography and COVID gave me a better understanding as I got a work hiatus.  I initially got poor results until a month later I gave it another try on a bright sunny day.  I then spent the time and learned how to use it and more important WHEN to use it.  Once I learned the device I bought the TC-2001 as well.  I use both but only when appropriate.  In my opinion they are both great when you are shooting the sun, the moon and wildlife on bright sunny days.  Those are typically the only 3 times I use them.  Of course other bright and sunny times could apply that are not wildlife like surveillance.  I have actually had some success on misty overcast days but only after I learned the triangle well enough to compensate (aperture, shutter, ISO).  I had a still eagle one day and he was still so long I got kind of bored on that misty day as I shot probably 100 pics of him doing nothing so I said 'what the heck' and put my TC-2001 on because I had nothing to lose.  I played with the triangle until I got some wonderfully close up shots even when overcast.  I probably got 800 horrid shots until I found the triangle combo that worked.For wildlife they are fine if the wildlife is still. For fast moving things like a bird in flight, so far my skill level is below par on focusing quickly. I should note that I have a injured index finger that makes focusing with my left hand while I hold the body painful unless I go really slow. I am sure some less crippled people could pull this off particularly if the bird is not flying towards or away from you. IF you use a tripod this might work, I don't know I rarely have a tripod ready where I go.FOCUS:TC-1401: With the TC-1401 I am able to focus automatically throughout the ENTIRE range.TC-2001: With the TC-2001 you lose auto-focus at about the half way mark of the lens (300'ish) and it will still try to focus after that but will not lock on. You can get close with auto focus and then switch to manual focus.TC-2001: At 150, 180, 200, 250, and 300 (lengths on side of lens) auto focus worked pretty well.400 and up I was not able to get it to focus except manually. It would just dance in and out of focus, unable to lock. Still, with manual focus I am able to pull off shots with bright light.F-STOPS:TC-1401: (only changes listed)150mm = F7.1-F32200mm = F7.6-F36300mm = F8-F36400mm = F8.5-F40600mm = F9-F42TC-2001: (only changes listed)150mm = F10-F45200mm = F11-F51400mm = F12-F57600mm = F13-F57STACKING:Either I suck at puzzles or you cannot add the 1.4 and 2.0 together.Like anything else you have to learn the tool before you trash the tool.  I use both teleconverters with a crop sensor D7500 which gives me an equivalent of 1800mm.  I am happy with both teleconverters.  If it is cloudy on a birding day they stay in the case/bag.  I shoot both mostly handheld (so usually with a really fast shutter speed 1500+ if at furthest range while hand held).  I only use a tripod on moon/sun shots and even then not always with a tripod.There is a FB group dedicated to the Sigma 150-600c which constantly posts pictures with and without both teleconveters.

    Upon pixel peeping - impressive
  

*by P***. on Reviewed in the United States on April 22, 2018*

I've tried a couple solutions to getting better reach with my DSLR over the past two decades.  As time goes on it seems I throw more and more money and the desire to create deep compression and get background separation for a given subject - usually birds but sometimes elements within a landscape and the occasional bison, horse, or zoo animal.  I've tried Canon's original 100-400mm, Sigma's 300-800mm w/1.4x tele (too heavy to carry), even tried a super 2000mm bridge camera - and now the Sigma 150-600 Sport with this 2x teleconverter.I was skeptical because it doesn't support AF.  The support sheet on Sigma's web site doesn't expressly tell you it doesn't - it simply states it only works with lens to f/8.  I initially took that to mean the lens would work in AF until I zoomed past the point where the equivalent f-stop was beyond f/8.  That's not what it means - it will not even attempt to auto focus.  I tried it on my Canon 5D mark IV and 80D - neither will support auto focus at any focal length with this teleconverter and the Sigma 150-600mm Sport.With that said however, this combination is super sharp.  With the tele and the zoom lens set to 150mm you have the equivalent reach of 300mm at f/10, zoom in and you are at 1200mm and f/13.  I took some test shots with strong back lighting to see what the chromatic aberrations would look like and after peaking at 300% they are very manageable.  If Adobe updates LR's lens profiles to match this specific combination I'm sure it'll be even better.In bright daylight I was collecting test shots zoomed all the way in on my Canon 80D as wide open as possible at f/13.  I was shooting around ISO 1,600 to 2,500 between 1/400th to 1/800th of a second depending on the lighting conditions.  For me this is really on the edge of the quality I'm looking for.  So if it were to have taken anything away from the image - say contrast or add too much of a light cast I'd have to return it.  I was able to manually focus well on the 5D mark IV but on the 80D with it's smaller and less bright viewfinder I had a little trouble and was second guessing myself a lot.  However, back on the computer I had a good percentage of keepers.  For comparison on the Nikon P900 which has an equivalent zoom of 2000mm.  I'd say my shot success rate is better on the Canon 80D and when I do get a shot the edit-ability for highlights and shadows is much better than that tiny sensor on the Nikon can provide.  With the Sigma 300-800mm with 1.4x teleconverter I would have lamented getting the tripod and stabilizing head out but would have had almost all keepers and at better quality - of course at about 400% more the price for equipment.In my opinion if you are the type to take your time finding a subject, tracking it and learning it's behavior then you'll enjoy this accessory.  If you're looking for more reach on your APS-C camera for hikes and don't like using a tripod or waiting around for a second or third chance than keep looking for another solution as this one will likely frustrate you.Despite the obvious shortcomings with the autofocus issue, the lack of even an autofocus confirmation beep, and the unavoidable added weight the quality of image produced makes it work having around - I'll be keeping mine.The attached photo is from the Canon 80D, the focus ring distance scale indicated just shy of 100' - harsh back lighting demonstrates the chromatic aberration suppression of this tele/lens combo and is about as bad a lighting as you could possibly get.  I was pleasantly surprised I was even able to recover this.  At 300% a little chroma, pink and green ghosting on edges was visible but as you can see I was able to correct for it.  The shot is cropped down by 50% to 12.1 megapixels so you can see any issue a little better.  Shot at 1/800th, f/13 (Wide open), ISO 1,600, and a focal length equivalent of 1920mm.

    works good, except for manual focus
  

*by S***F on Reviewed in the United States on May 30, 2021*

The teleconverter works really good. The downside is it's autofocus doesn't work with the 150-600mm contemporary lens, so if you are jumping from one subject being in focus at one distance, you will need to adjust by hand if you want to quickly take a pic of something else that is at a different distanceOne thing worth noting that I found very odd, autofocus does not work (as in the functions disabled) when using the view finder of a Canon T6, but the autofocus function does work when using the live/screen view instead of the viewfinder
