   …I am a Nature-Photographer, and as such, often need to get closer to my subjects while still remaining safe and not disturbing whatever my telephoto-lens are pointed at. I have several long telephotos, but they become bulky and heavy as magnification increases… therefore, the most practical way to increase that power is by use of an excellent quality telextender. I use many Sigma lens, so purchased the Sigma 1.4 telextender, and after doing comparison tests with and without it, I can see the most minute loss of sharpness…to the point where it is not a concern at all…especially given the additional magnification power I gain by using it! It adds only 1-inch in length to the already long and heavy lens…and weighs mere ounces..making it basically ‘invisible’ while using the lens…andt the results are excellent, so that is why I say this is gain-without-loss!…

   The media could not be loaded.I’m a Nikon shooter from way back but I love the capability of the super telephoto lenses that Sigma makes. This teleconverter lets me enjoy the best of two worlds! Its compatibility permits. E use use all the features of the Nikon camera bodies and at a decent price!

   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.

   I bought this to use originally with my Nikon D7500/Sigma 150-600mm. Pictures were sharp and I loved the added reach. Only problem I had was it was slow to focus. I’ve had this for a little over 18 months and with practice, had improved on the focus issue. There was still a delay but it wasn’t as much.I recently purchased a Nikon D500 and tried the teleconverter with that camera. I had to remove it-I CONSTANTLY lost the ability to autofocus. I switched it back to the 7500 and works like a charm. It’s supposed to be compatible with the D500 but you do not have all functions.

   This is a great teleconverter for the Sigma 150-600 mm contemporary lens. It DOES autofocus even at f9. Remember that it reduces your max f-stop but still creates sharp images. It can be difficult to get a fast enough shutter speed when shooting wildlife or sports, which these are generally used for on long telephoto lenses, so bright light is necessary. I use this teleconverter on the Sigma 150-600 contemporary on a Nikon D7100. Note that it ONLY works on three lenses designated by Sigma which are the 150-600 sport and contemporary lenses and the 120-300 sports lens. So don’t buy this teleconverter with the intention of using it on all or any of your other lenses. Also, Sigma does make another 1.4x TC but it’s less money and is NOT the same as this one. Be sure you get the TC-1401. I tried the other TC when the salesperson at the photo shop gave me the wrong one. It AF’d very slowly and was not as sharp. Fortunately the price is $100 less expensive so that tipped me off. When I specified I wanted the TC-1401 and I attached that to my lens it was MUCH sharper and faster at AF. I’ve attached two photos, one a crop of the other, otherwise NO editing, i.e. sharpening, clarity, etc, has been done. The TC was attached to a Sigma 150-600C lens, on a Nikon D500 body, set at f9, 1/320.
