I hope this EXPLAINED video about adapters, speed boosters and crop factor was helpful. Did I cover what you wanted to know? What else did you want to see or learn about. Would love to know what you think. Which do you plan on using, or are already using and with what lenses.I am grateful in advance 🙏 ⭐️ Buy the Viltrox EF-M Speed Booster: geni.us/yTKWY (affiliate) ⭐️ Buy the Metabones EF-M Speed Booster: geni.us/pxaQK affiliate)

Every other youtuber explaination: "Speed Boosters pretty much work like magic" Sagi: "Let's dive into the pythagorean theorem"

This is a legendary level of nerdy😍🔥 love it tho! An Interesting yet a confusing topic, thanks for sharing the knowledge

Finally! Contrary to other channels You explained everything without "sensor war" bias. Without omitting certain details to suit agenda. Very informative and on point. Kudos to You. Your channel became my favourite regarding photography gear. Keep it coming. Thank You. :)

Hey, Man! I was really confused about this topic and you just made a video! KEEP THE CONTENT COMING

I just discovered your channel about a week ago. Everything I've watched so far has been immensely helpful. Your presentations are clear, concise, and informative. Thanks for the education!

Superb tutorial. Other platitudes are available! Seriously, that's probably the best explanation I've seen anywhere. Been taking images for almost 50 years and you've impressed me! Thank you.

This is a fantastic video. I had a super basic understanding of some of the crop factor effects, but this has expanded my brain understanding ten fold. I really like these educational type videos to help improve understanding of the little things to help improve skills and abilities within photography. Thank you.

Your channel provides value and great information. Even though many other content providers mention the same topics. You have a great way of explaining it to the masses. So thank you, for the 10 of thousands of hours you have spent thus far editing and composing the channel.

This was an excellent video. You clearly explain everything for anyone to understand it. You are a good instructor . Keep up the excellent work you do. Many thanks.

I knew all of this, through what I must say was quite an extensive research, reading articles, watching multiple videos and linking it all. This video is probably the only which explains it all together in a simple manner! Really great work!

Sagi, kudos man! I have been watching videos on your channel for a few year now, and you are such a great reference for both gear and for general knowledge pertaining photo and video. Just wanted to say thank you for continuing to put out stellar content, and I'm happy to see the channel growing. 110K subscribers and growing and you have certainly earned every one with the high level of production on your videos. Although I was fairly well informed about these topics, there was still some useful things I took from the video, and tbh, I woulda watched it all anyway cuz the videos you've been putting out are so on point. Keep up the good work!

these videos are incredible. keep them coming! i'd love to see someone discuss the evolution of sensors; I been recently obsessed with the magic behind bayer cmos sensors that DJI and some others are using. i'm not sure if it's completely applicable to what you like talking about on your channel, but some of these advancements/tricks are pretty fascinating.

This is the most detailed explanation that I’ve seen. Very well done! I have and use both depending on the lens and what I’m trying to achieve.

This has to be the best explanation of F-stop, Focal length and how they work together with a camera with or without an adapter. Thank you!! This was awesome and I haven't even gotten to the actual adapter vs speed booster part. lol. Well done man!

Man your content is great, you had my full nerdy attention on this one, it really cleared up a lot of stuff I was a bit confused about. Thanks!

This is why I love you channel and content so much. You don’t try taking subjective matters and making them objective: you just lay out the facts in an easy to understand way so we, the viewer, can make informed decisions.

I’m so glad that this can all be explained but I still have a hard time understanding. That was a lot of math. Great job. There are some amazing folks creating all of these advancements. So cool.

Man, this is a PROPERLY DONE video. This is probably what people teach in those paid courses. Great work!! Thank you for this knowledge!!

Great Informative Video! I have gotten into cameras recently with buying an M50 a few month back and my ADD self is soaking up this content like a sponge! I'm learning so much more here watching your videos than what i'm learning at Uni haha keep up the great work Sagi!!

Brilliant video, the best I have come across so far. Extremely well explained, not just about the adaptors but also the crop factor and focal length, the aperture, the field-of-view etc. Thank you so much.

I think this is a phenomenal video and is the first I have come across in 5 months which explains in detail the difference between full frame etc. I got a bit lost in the math at the end but I would love more videos of this detail as it has demystified some of the jargon!

Hey buddy, I just keep coming back to your channel you have so much good info. your delivery makes It very easy to understand and grow my understanding of photography thanks Sagi.

I can’t believe I just watch the whole entire video with all those numbers in it. And somehow kinda understand all of them in one go. You’re so good at explaining things!

Great video Sagi! This was something that I already understood pretty well, but I'm glad I clicked anyway because I understand it much better now. I didn't expect you to go into all the math. Thank you!

I really needed that explanation!! Thanks!! :D

This clarified so much confusion for me, these are awesome type of videos I want to understand what the numbers all mean so I know wtf I am doing!

Thanks you for considering my request for this video. Clear and detailed explanation. Video also covers many basic things more than just the speed booster topics. Keep doing great videos like this. 👍

I've seen many of your videos, but this one may be my favorite so far. Lots of cool information very clearly conveyed.

I stopped the video to say thank you. Honestly your tech videos are very inspirational and informative. Your channel is by far the only channel I jump to view nowadays. Thanks!

Spectacular video! I was wondering about speed boosters and you explained it clearly. I really love your channel. Keep up the great work.

This is straight up the most in-depth video explaining the topic I've ever watched. I know this is old but damn... 100/100. Fantastic and informative video.

Really well done video. I’m sure a lot of people won’t watch it all the way through, but hopefully that doesn’t dissuade you from making more meaningful content like this.

Thank you very much from Finland, 🇫🇮, interested in M6 mark 2, you are the first source I understand and that makes camera world so much interesting.

finally someone who explains the numbers and helps my brain to see what I didn't see before. Very helpful!

Most informative and the ULTIMATE video on this topic. Every photographer must watch this video once in their lifetime. (Many photographers don't know the physics behind this.) I am not not exaggerating. This is an amazing content, Sagi.

This is a great explanation! I wish I had this sooner, it would have saved hours of research I had to find on my own.

This video is super helpful and detailed. It's one of those that will stand the test of time, and be relevant YEARS from now. Fantastic content as usual! Why go to school when you can just find this type of content on RU-vid?

I feel My cpu has overheated i have to come back later

Thank you! This video gave me a couple of light bulb moments and will help me with lens choice as well as adapter choice.

Finally opened my eyes, thank you! Have a great day!

Bro this was deep but I loved it LOL. I went with an adapter for my M50. Thanks for making the video

Got my first real camera recently and this is the Channel that is giving out real knowledge.

Thank you sir 🔥 I was bit confused with other comparison videos. But you explained it so well. Now I am going to buy both. 😇💯

Amazing work as usual. Best photography channel for beginners and intermediate by far! cheers from Argentina.

Thanks sagi for this content, I am amazed how you explained this. And for me, I'm glad I have both adapters so I have options based on my preferences

Very nerdy but filled with very very important information. Love it 💛

Awesome explanation of everything you went over there’s a lot of amateurs out there making videos and blog posts that make it hard to know what’s what but it’s clear you have a firm grip on the subject 👍🏻

I love the depth of explanation here. Brilliance my friend! 🙌🏾

Sagi this was super helpful! I’m looking forward to the follow up video because I’m learning so much about cameras. As always thank you man. Keep up the great work!! :>

Love it! This is by far the best explanation I have seen.

I'm not sure how this video relates to cameras but after watching this I was able to ace my geometry test!

I had to watch the video twice… but now I really understand the difference, and how it actually works. Thanks a lot for your didactic approach!

Wow. I'm actually now understanding it the 2nd time around. The 1st time I watched this a few months ago I got dizzy (ziggy) ... Lol. But it actually sank in now since I'm now about to buy my M50. Thanks much. Your effort wasn't in vain.

in all honesty this is one of if not the most clear videos out explaining the crop factor.. keep up the hard work really!

That was pretty intense, Sagi. I’m going to have to watch this a few times 😄

This video is excellent! Great explanation of focal length and aperture,. 🙌🏼

This video is gold, thank you for all the great info!

Wow you explained that extremely well. I did not lose my attention throughout the whole video. You’re great at this. Thank you for sharing the knowledge

Your video was very helpful. Thank you very much. I'm not a math guy, but your explanation was very easy to follow and now I know what my needs are in terms of adapters and speedboosters. :)

Explained so well ! This video is being book marked - to be referred to and to share it with others ! Thanks much

Love your style and information delivery. Thank you for sharing.

I’ve watched a few of your videos and appreciate how you break down the information. I’m new and I’m looking at the canon m50. Thx again.

Wow, a very detailed and very clear explanation of all this. I know this video took some time to make, but thank you for showing all the math and a clear and precise explanation.

The best and most lucid explanation on this topic! 🙌🏻

Wow! what a deep (but enlightening) dive into the math of how crop factor functions. Thank you!

Wow, what a wonderfully informative video! You went above and beyond, dude!

New subscriber here! Just bought the m50, made the mistake of reviewing mark ii comparisons and immediately thought I made a mistake. Thanks for making so much content about the m50, in large part your videos helped my decision and also talked me off the mistake ledge, lol. You’re videos are great and easy to follow for a novice like me. Keep me coming.

You’re such a great instructor. You make the difficult easy to understand. Thank you.

I studied technical photography at RIT and we were DORKS! And yet I never knew the math behind F-stops. Your explanation makes total sense. Your videos are great! Thanks!

So glad I found this channel! This is everything!

There is a difference between a review made by an user and a pro like you! Man best video ever on the subject. Thank you for it. You’re totally the best!

this channel is super helpful and informative!

Best explanation video on the difference between adapters and speed boosters yet!

So grateful I found your channel. Finally I gain access to some real knowledge. thank you! :)

Oh my gosh! Actual maths 😃 Simply the best explanation of focal length, aperture and crop factor. E-v-e-r! 📸

Why is this the first time i've heard somebody explain this, vey well said. Thank you 😃

Great video man! I learn a lot from your channel, thanks for sharing you knowledge

This is the best video I've seen that explains speed boosters, focal length and aperture in a way most people will be able to understand. Good job!

Great video mate, really enjoyed it. I’ve literally been watching your videos since getting into photography but was not subscribed. I am now!

Real information is very important over the fluff of opinion. You have cleared up many mysteries for me. Thanks for your professional presentation.

Wow thank you I have never know any of this nor a photographer. Started researching to take some product photos for my ecommerce business and you nailed it. I completed understand what other videos are talking about now :D

This video is so good, huge props for explaining it so clear 😄👍

Thx, this is the first time I have seen a bideo explaining this right. It has taken almost a year to deduct what you just presented in this video

I seriously need to commend you on the amount of effort you put into this video.

I've never understood something so good before, your explanation about camera's is exceptional

You explain this so much better than I do. Many people don’t understand these concepts, but are quite willing to tell you that you’re wrong. Thanks!

Sagi has a way of explain things that makes it clear. Now I want a speed booster...and know how and when to use it. Thx for putting this video together. I'm looking forward the one about aperture.

I use the Viltrox speed booster with a 35mm EF F2 lens for my webcam setup and its beautiful. No problems with autofocus and I have the advantage of the extra stop of light. Turns the M50 into a full frame camera.

I have the M50, with both the adaptor and the speed booster. I will put on either the Sigma 30mm f1.4 or the Sigma 85mm f1.4 Its like having four lenses and I have been very pleased. I very much enjoyed the video. Nice to have that much detail on the subject. Thank you.

Great content! Educational & helping me to level up my understanding to improve my images

Seriously textbook/ college level explanation! Thank you for being awesome 👏

I am so glad you didn't stick to the party line of "forget about crop factor" because it doesn't change the focal length and dove into the real issue that it does change the 'effective' focal length. Most of us who know something about optics were only confused that some ppl were confused or misrepresenting this. The bottom line is "It doesn't matter that it doesn't change the FL. because crop factor does affect the results which is, It looks like it changes the FL. as in a 1.6 [canon aps-c] crop factor makes a ef 50mm "ACT LIKE" an 80mm. what I wasn't yet sure about because I had not yet researched it was the f-stop. It makes so much sense how you explained it. Other youtubers either ignore the basic math or get it wrong by multiplying one number but not then multiplying by the next. EG: a 50*0.71*1.6 being 56.8mm [effective] is the math of the speed booster effective FL Now, for me... I have an EF 78-300mm f4-5.6 and while a 120-480mm f4-5.6 doesn't make sense for weddings, with this info, I can see how having a 85-340mm max at f2.8-4 does make sense For other lenses and primes that aren't available on ef-m yet, a 35mm becomes a "nifty 50 with just an adapter, and now that I know that the f stop won't change, it's going to be both for me. What I'm now confused about is, why isn't the 22mm prime an effective 22 mm? Is it in fact, an effective 36mm?? and why? EDIT: he answered this but it wasn't that clear. Yes, you apply the crop factor to ALL lenses. That means the 22 prime is basically a 35mm when compared to a full frame camera with a 35mm

I watch your videos from Colombia, you are the best teacher ever, each video is pretty much better than previous.. now i learn photography and english, thanks for speak slowly , i really appreciate it. 🙏🙏🙏🙏 thanks a lot.

Amazing, well-detailed video. Love from Kenya.

Best discussion of this I’ve ever heard. Bravo!

Wow, I just learned something!!! Great video my man!!! Thank you!!!!!

Amazingly explained! Thank you

Thank you for making this video! It has helped me immensely.

I've not used the sq function on the scientific calculator for 20+ years! Great video and nice math refresh as well!
