ARE EXTENDERS WORTH IT? Find out from someone who's taken 500K images with them!

I should have said more plainly...don't buy the 2x until you've mastered the 1.4x...it's much harder to get good results from it!

Love how you're straight to the point and don't have 15 minutes of fluff and 3 minutes of actual information like most youtubers

A LOT of other youtubers could take lessons from you on how NOT to waste the viewers time. I learned more from you in 13 minutes than some 1 hour videos I've watched. Well done sir. Well done.

This is random but I work as a wildlife photographer for a Nature Educational Center (very large wetlands) …and I actually made a new photography bud recently because while I was out shooting, another photographer walked up and we started small talking …next thing I knew, we found out that we both watched your videos haha. Thanks for sharing your knowledge and bringing photographers together!

I swear this is the first video that explains this topic super well. Thank you so much!

Simon, the way you edited this is excellent. I can tell you really care about conveying information clearly and quickly. The way you cut the talking head portions makes this come across super sharp and intense, like a professional TED talk dialed in for max impact. When I say intense, I mean, it's engaging, it catches your attention, keeps your focus, and ensures that each point sticks. It's a really effective style. Solid video and props to you for taking the time to edit and cut appropriately to refine your message. Much appreciated!

Also, great job on this video - starts up and just starts dropping the facts right away. No fluff, no filler, no padding it out to increase your run-time. I love it!

This really is good information and clearly presented. Beyond that, I personally think too many photographers become obsessed with examining subtle differences as shown in some of your comparison photos, rather than the overall image and what it conveys (or should). Non-photographers rarely get caught up in this as they are content appreciating the image or story captured. This is not to suggest we shouldn’t be aware of the tips you provide and trying to capture the sharpest images possible, but rather keeping all photographic elements in perspective. And, I think my comment relates more to amateurs and even serious enthusiasts rather than dedicated pros who are at or near the top of their game.

I'm an amateur who has primarily taken photos of airplanes & details of them. I've ben watching your videos & they are full of helpful (when I can remember everything!) information. I have watched a few multiple times to try to remember & put into practice what you present. Thank you! Your videos are very helpful to even an amateur.

The EF 70-200mm f/2.8 L IS USM II is another. My wife uses her EOS RP with the EF to RP adapter, 2x extender and the EF 70-200mm L f/2.8 IS USM with a very sturdy Manfrotto tripod to take excellent images of a full moon. She's woken me up at 1pm to check the moon and we have all the equipment ready to set up on the back patio. We buy nearly all of our high end equipment used from the popular sources and the condition has always been gently used with very low shutter count. The combination of low prices to get into the best lenses and nearly new camera bodies and accessories has made photography very enjoyable.

This is a real professional.

Easily one of if not the best photography channels on Youtube

This is the best teleconverter video that I have seen. You explain the pros and cons in a logical order and provide specific use cases for 1.4x and 2.0x converters.

Brilliant explanation of using convertors thanks for posting

I have 2x and use it with 100-500mm and it works great. I love it. But it is not always the easiest to use. But in certain situations it is extremely helpful.

I had watched this months ago, but since that time i bought both a large and fast prime and similar zoom second hand and they came with OEM 1.4 and a 2x TC's. I've done a couple of thousand frames with them, both HH and TP, and some of the results (and repeated attempts) have left me both disappointed and perplexed. Aside from the run through and great tips, what i thought was excellent in this video were your comments linking that to the variation you have in the quality of your hits. Reassuring to know that, even while you may rarely be as perplexed as i am, you do at least occasionally register disappointment. All the very best, mon ami, and thank you as always. Cheers from NZ.

You are so generous sharing your knowledge and I get so much more out of your videos than the majority of YouTube photogs. You are succinct but thorough. My time with you is well spent. Helpful to hear how long it took you to be proficient. You are the first pro to tell me to “mash” my eye against the camera. Thank you cause I needed to hear that!

Exceptionally well put together video. Your information is very clear, relevant and easily understood, much like all your other videos. Really enjoy your content, keep up the great work!

As a bird lover myself, your work is fantastic. For people with the SLR, they should be able to program mirror lockup and use a “bulb” to avoid the largest sources of vibration.

Thank you for sharing your experience and knowledge in layman’s terms. Very informative and helpful.
