Jason, thanks - I appreciate videos where someone actually gives a lot of good info about the topic being discussed without being repetitive or doing things that waste time, and your video was really great in this regard.

Excellent! Your teaching here is succinct and superbly delivered. Thank you!

Very helpful. I've considered purchasing a teleconverter for some time. You've confirmed some of the concerns that I had. This was educational. Thanks.

Thanks for the tutorial Dr Jay. Very clear!

Looked everywhere for information of this quality - thank you!

Thank you Jason. Good info for a beginner.

Great video Mr. Jason thank you.

I enjoyed your discussion. Thanks!

Thanks for posting the video, very helpful.

Thank you so much!! very informative piece of information!

Great info! Thanks for sharing.

Thanks Jason for a very rational approach to what seems like "magic" at firrst glance. I shoot Canon and for the price of their teleconverters it comes out looking like a major compromise. I am going to sell my 70-200 and get the 100-400 to get what I need for my photography. It's hard enough getting wildlife to sit still (without ACTUALLY shooting them) at f2.8, much less at increasingly slower speeds with the teleconverter. Just stick the 100-400 on and be done with it.

Very informative, thank you very much and keep up the good work!

Thanks Mr. Jason Odell.

Jason, Thanks for the information. I photograph Sierra Nevada Bighorn Sheep and use a Sony A7R2. There are no E mount lenses long enough. I adapted an A mount 70-400mm lens and just bought a 2X Sony teleconverter. I am hoping the camera can deal with this because the sheep don't cooperate when being photographed.

thats brilliant jason jeas i rekon id have enough focal length thr at that 448mm max focal length,id be hoping to get surf shots from a clifrf and i would have thought between 300 and 400 shud be enough to get a half good shot,i was going to go for the 2.8 aperture lens so that shud still get me sharp shots at full zoom extension shouldnt it would you think,it will also be grt to use the lower zoom for other general photography also again thanks a million for the informative reply cheers.

Good vid mate, very informative.. Thank you.

Great Tips this helps out a lot

Thanks a lot Jason.

excellent explanation, thanks !

12 years from upload I watch your video 😊

I have a nikon d5100 body and i plan to buy a nikon 200-500mm lens. i might buy a tele converter in addition. Is this a good combination looking at the fact concerning the auto focusing?

Excellent! Thanks!

Thanks for the tips.

which 2x teleconvertor I should buy for my Nikon Nikkor 70-300mm AF-P VR lens ?? and I have Nikon D 5300 DSLR camera please help me out for this.

Thanks for those wonderful tips

Very good explanation! Thanks

Hi Jason, What teleconverter will work on a Tamron 70-200 F2.8 VC mounted on a Nikon D750. Thanks in advance.

sorry sir if i have nikon af d 80-200 f 2.8 is this can use tc 2x nikon brand sir? how about the autofocus speed and diafragma still can be setup from my dx body? how about with kenko pro 300 tc 2x? is this same?

Hi. tell me are these tele-converters compatable with the 400 mm f/ 2.8? Will it be fast at 800mm f/ 5.6, asuming using the 2x? thanks!

@redmeaux the largest lens is the 70-200 f/2.8 AFS G VRII Nikkor. There are no limitations with F-mount Nikon bodies and TC's, the issue is simply lens compatibility.

Any Teleconveretor For D5200 im using 70-300mm manual lens plz sir reply mee

Great info Thank you Steve UK

Jason, Thanks for the clarification. Thanks to your video, I've decided against buying the Nikon teleconverter for the 70-200 F 2.8. I mean, I already have a sigma 150-600, then why should I invest in this teleconverter. Well, the one reason I was thinking of was the hardship of carrying 2 lenses. But then, I already have it. If i'm going to lose 2 stops of light, I might as well use the Sigma 150-600. Thanks,

Thanks for the review ! I do have a Nikon300S and the 105mm Nikor lense . would you tell me which one is the best teleconverder for my set up ? Thanks !

I use the 300.mm lens first shown and didn't know that a converter would not work, thanks for the advise as I think a new lens is on the shopping list.. Though the 300 is great

Thanks for sharing tour knowledge

Converters are really only handy in good light - not in low light. That is my take on it. I at times use the TC-20EIII 2x Nikon on my 70-200mm F4 and can shoot at F8 but it really needs F11 (400mm) and you need to watch your ISO depending on the light and maybe give it a bump up especially if the subject is not stationary. It's really about understanding the balance and trade-offs and if you know those and understand the limitations, then it is useful.

what focal range willi get with a canon 7d crop sensor camera ona 200mil f2.8 lens with a 1.4 converter would anyone know

I've just bought a 70-200 2.8 VRii and a TC 20e iii. I'm hoping for good things!

thank u so much! ur review is very helpful :D

Thank you so much,,,.

I use my Sigma 1.4tc on my Sigma 150-600 Sport f5-f6.3 successfully with both my 7DII and 5DIII picking up AF quickly across the range and giving sharper images than a crop would. However, it does require good light and I can’t guarantee being able to use it every day and it’s really important to fine tune your lens with the USB hub (or micro adjustments in camera as is the case with my 5DIII which are inferior) before even considering using it. Any front or rear focusing is phenomenally exaggerated, as are any other issues. I don’t even try to use my 2x tc on this lens and camera, even if you could use AF with it, which you definitely can’t, you lose far too much light even on a good day. The Sigma won’t work on all lenses because of the protruding front optic same as Nikon.

Is it there any teleconverter for TAMRON AF SP 70-300 F4-5.6 Di VC for CANON? Any recommendations? Is that ok or...?

hi jason.....that was nice information.thanks...I would want ur advice on a tc for a 70-300mm nikon. also plz let me know the demerits in advance

You're effectively getting a 35-70mm f3.5 lens out of that, with possible image degradation due to the teleconverter even if you can find a compatible one. Given the sheer size and weight of the lens you're starting with, it may be easier and possibly cheaper to buy a lens covering the 35-70mm range, which will be much smaller, lighter and handier. I'm putting this up for those who are considering doing the same thing. I hope you have not already found this out to your detriment.

Dr. Odell. When taking moon shots with Nikon D750 DX body, can I use TC-14B telecon w/ Sigma 150-600 f/5-6.3 Contemporary lens at focal length 600 mm? I always use sturdy tripod and remove shutter. Please suggest. Thanks, KK

nice review. Like it.

and what converter should i use if i dont lose autofocus

PLEASE ANYONE i have a nikon D5000 using the 55-200 mm lens i am thinking of buying a 2x tele-converter but how much quality loss do i get and can i still autofocus please respond

hi jason i have a d300 and a sigma lens 170-500mmD 1:5-6.3APODG. can i use any of these three teleconverters. if i can which do you think would be the best one. i am into wildlife photography but still in amateur stage.

I'm starting astrophotography and I was considering getting a teleconverter to make some of the smaller objects larger so I don't have to crop as much. It would all be compatible with the telescope and I'd be taking multiple long exposures at low ISO. Also I'm using a D800. Can you see any problems with that?

Help!!!!! I have a Nikon D3200 .I use the lens Nikon DX VR AF-S NIKKOR 18-55 1:3,5-5,6 G II and Tamron AF 70-300 f/4-5.6 LD Di 1:2 Macro telphoto lens for Nikon 70-300mm F4-5.6 zoom lens with built-in motor (A17NII) ....I'm interested in compatibility N-AFD 2X Teleplus MC7 KENKO with my camera and lenses I use? Will they do all the functions, autofocus, aperture and shutter priority, and lenses motor/engines? I am interested in buying N-AFD 2X Teleplus MC7 KENKO for Nikon .

Good advise.

How about for the sigma 70-300 Nikon mount

Practical feedback: I shoot mostly landscapes, but for some fun budget birding (, I use a TC20E-III with my 70-200 F/4G on my Nikon D810 (in DX crop mode) giving me an effective focal length of 600mm@F8. Not ideal by any means but I have successfully gotten a fair number of pretty decent shots of birds in flight - and many excellent ones of stationary birds.

Tom Burchill That combo works surprisingly well with the D810 AF system!

What about "Plan C = Crop"? The discussion of teleconverters (Plan A) vs. very long lenses (Plan B) often overlooks Plan C: Crop. If you have in mind to put your image on a poster (or billboard!) you may need all the pixels you've got, but if you're heading for 4x6 or even 8x10, then a fraction of your sensor's pixels may be plenty. (Example: 300 dpi x 6" = 1800 dpi, cf. 5600 pixels on Canon 5D Mark II's long axis), so 1/9 of the sensor area might produce an excellent 4x6 print. Reactions?

Will it work on the Nikkor 55-300mm lens?

how you calculate the loss of stops ?

good explanation!

I am thinking to get a 55-200 and add a 1.5x teleconverter to capture the moon, do u think it will be a good buy because I can use tripod and relatively longer exposure to compensate? Just a thought, if not should I get 70-300 or 55-200 which one is better?

well explained very useful

I have a Nikon 300 f/2.8 lens with a Nikon D500 body. So does this mean I'm losing f/stops before I even put a TC on it?The reason I ask is that I'm thinking about putting a 2x TC on this lens.

@JasonOdellPhoto

Your camera has no effect on the maximum aperture of your lens. Your 300/2.8 will operate at f/2.8, but on a D500, the angle of view is the same as a lens 1.5x longer (450mm). When you add a teleconverter, then your effective aperture is reduced. With a 2x TC, the lens becomes effectively a 600mm f/5.6 lens. On the D500, the angle of view is reduced by the crop factor of 1.5x, so it would be like using a 900mm f/5.6 lens.

how about primes like 50mm 1.2 - 1.4 - 1.8 . thats 3-4 of a stop right ?

Hi, one question: I have a Canon EOS 600D (T3i Rebel) with a 18-135mm. I would like to get a 2x teleconverter. Is there any problem?? Which do you recommend me to get?? Thanks a lot!! Cheers!

It's certainly compatible. Expect it to be a little soft wide-open and make sure you use focus fine-tuning to optimize the focus.

Adding a 1.4x TC to a 200mm lens gives you 200 x 1.4 = 280mm. On a Canon crop-sensor camera, the angle of view is effectively the focal length times 1.6. So, 280 x 1.6 = 448mm effective FL.

Hallo Jason i have a EF 70-300mm USM lens can i use a teleconverter.Thank you

No. Autofocus will not work as your widest aperture will be f/11 at 300mm.

Pentax AF TC 1.7X is one of the best... a) works with any K lens b) does AF even with manual lens c) optically is the top

Why crop when you can put more of those pixels on your image? True, cropping is an option, but you have to consider situations where you want to fill the frame as much as possible without cropping to get better quality.

Thanks for your review mate! I have one big doubt. I have a cropped sensor body and I like to shoot wildlife. I brought a Sigma 70-200 f2.8 for that reason, and as far as I could learn, this Sigman represents me a 112-320mm with an F4,5... (I recently learned that we should not multiply only the focal lenght but also the Apperture for the Crop Factor (in my case 1.6). So, making a long story short, if I add a teleconverter to this Sigma, lossing 2 stops will it represent me a total apperture of 8,6?! If so, I think a teleconverter to a crop sensor is not worth at all... Can you confirm if my calculations were correct? (The teleconverter I would buy was from Sigma and it is compatible with the lenses I brought). Thanks for your feedback, Cheers

I agree with Vincent but not entirely. Remember you are using a full frame lens on a crop sensor camera so the pixel pitch is better than using that same lens on a full frame camera for wild life photography. I don't do wild life photography but I do from time to time play around with my Sigma 2x converter on my crop sigma 50-150 f2.8. I was able to capture the attached picture. I don't remember if I used any exposure compensation in my camera for this shot but I did at .6 exposure in lightroom plus a couple other tweeks. And note this is crop sensor and crop lens which is not as good a set up as you have for wild life photography. I think, if possible, you should test it to see what you think or do a little more research into the issue consulting those that do wild life photography. www.flickr.com/photos/144987688@N06/shares/Vm077d

A 2.8 becomes f4 with a 1.4 , which is the only converter i would use

The best choice would be the TC-14EII.

Are those figures true for all teleconverters or just Nikon tc's? for example I'm thinking of getting a sigma 2x tc for my 70-200 2.8, would I effectively have a 5.6 lens??

Is the lens on the right a 70-200? Would the teleconverters all work with a D7000 or do you have limitations with cameras? Thanks for a great video. Miss the podcast!!!

I bought Tamron's 1.4x and 2.0x teleconverters for my 70-200 2.8. The autofocus never worked. Will Nikon teleconverters autofocus work on my D800 with a Tamron 70-200 f/2.8?

It will not work. At the long end, maximum aperture will be f/13, so AF will not work and the viewfinder will be incredibly dark.

so which lens is better 70-300, 55-200, better as in quality and sharpness as well as best bang for the buck

very helpfull :D

yeh it wil and it maby cut Your autofocus to if it is an slower lens i think for 2x convertrs the limit is 2.8

gud info :)

what if you use 200 teleconverters on one lens?

nice loud audio. thank you so much.

For those who want cut to the chase: A teleconverter WILL NOT WORK well at all on any lens that has a maximum aperture of f/5.6 or slower, nor will it work on lenses that are wide to telephoto range, like a 28-300 or 18-200mm.

No. Nikon TCs ONLY mount on AFS primes and certain zooms, like the 70-200mm and 200-400mm. Nikon TCs will not mount on any Nikkor lens that isn't a constant f/4 or faster. You could try a 3rd party TC, but your results will suck.
