Should you get Full frame or APS-C or Micro 4:3? What different visual effects do sensors create? Do you need different lenses? Is it worth buying one over the other? What does it all mean?!?!

Excelent video with a very good and easy explanation.Congrats !!!!!!

Hun Beng Tan says:

Great video, very detail explanation with illustration! IMO, one of the best video for sensor size comparison!

Michael Jones says:

Thank you!! That was an excellent presentation. I had purchased a camera with an APS-C sensor and had been considering trying to "move up" to a full frame camera. However, I realize now that I wouldn't realize any benefit from a full frame camera because of my level of photography (i.e., entry level hobbyist). Also, I didn't realize that the APS-C was almost 2/3 the size of the full frame. I thought it was a lot smaller. I truly feel better about the size of mine … the sensor I mean.

Wild Wisdom Journeys says:

Given that the Canon M6 II has a 32.5 MP sensor, is its sensor only 3.5 smaller than a full frame camera? Or are these different measures? Thanks for clarifying, Sylvia

Luis Garcia says:

Great video. Nice explanation, it all makes sense. Many thanks

Aristides Garriga says:

Excellent presentation.

I was looking at the Canon 90d, but with the announcement of the new cameras this year I'm leaning towards the EOS R. It's mirrorless so less weight. Still has a good size body (I have large hands). And the price is comparable to the DSLR body/ lens combination I was looking at.

cybertec69 says:

I shoot a D500 and D850, one is FF and the other is a APS-C, I use FF glass on both. What the APS-C does is give a a bit more reach "gets me closer to the subject" with the same glass do to the crop sensor. When the subject fills the frame of the APS-C sensor I get fantastic detail, same goes for the FF camera, does the FF give me more detail, yes "but only because the FF camera I mentioned above has more than double the megapixels", but just like the APS-C, the subject needs to take up as much as possible of the sensor. If the FF had the same megapixel count as the APS-C camera, the detail in the picture would be the same.
Depth of field is the same for both depending on the background and the distance between it and the subject.



bill baker says:

So I have a crop sensor camera the canon 7D should I buy just lens for crop sensor cameras?

Bigfarmer8 says:

I learned totally nothing new from this video. Yet, I watched it to the end because it was so clear and enjoyable. Great job!

bill baker says:

Very good video very clear and simple

malmedia says:

I suppose you wanted to keep this really simple so you left out a lot of exceptions when it comes to weight and cost, especially when you consider mirrorless APS-C and Full Frames.

Vageeshbabu Hanur says:

Sir, thanks for the vivid explanation. However, I beg to differ with you regarding a point or two. Now that Canon EOS RP is sold at $999 including adapter while the Olympus E-M D-E mark III at almost the same price, what is the price advantage the latter has? Secondly, the range and choice of glasses that Canon (or Nikon for that matter, maybe also Sony) has is tremendous compared to MFT glasses!

Bo Petersen says:

A very well explained video – hands down 🙂
But just as in many other videos about sensor size the real physics behind are either simplified, not really understod or plain ignored – sorry not to offend anyone 🙂
A bigger sensor does not, necessarily mean more details – unless you place more pixels on the bigger sensor – and it is easier to put more pixels on a bigger surface.
Light is a photons per surface area "thing" – either you get more detail or more sensitivity (more photons per pixel) – or a compromise :o)
The hole thru the lens does help very much to convey more photons to the sensor – bigger lens=bigger hole=more photons.
Given the same pixel size for all three sensor sizes you should get the same sensitivity and the same noise – if you get the same number of photons.
Try think about your three sensors native sensitivity ISO200 for the M43, ISO100 for the APS-c and most likely ISO60 for the FF – how does that scale with crop factor and/or full aperture area ?
I have not calculated the areas but you don't need to increase the diameter much to increase the area allot 🙂

Dave Salerno says:

A lot of good information to better understand all the options

Gilbert Walker says:

Brilliant video, Mark! Thanks for a clear and helpful presentation of the pros and cons of each system. I am an Olympus user, and I'm quite happy with both the size and image quality (as well as the price) of my system. Thanks again!

Michel Lonergan says:

Well done, you should an do extreme croping in the image to see what happening.

Ben Panesar says:

Great video simplifying the myths on sensor size when one enters the photo store!

Rakesh Kayastha says:

Thank you for a very helpful video!!

Lynne Gordon says:

Thank you. Very interesting and informative.

paul collins says:

I am the proud owner and user of a Canon 500d, it does everything I expect of it and more, the camera has taught me lots, with its kit lenses, I use it in manual mode, I bought it when the model first came out and won't be changing it anytime soon.

Armando R. Venegas Atencio says:

Very HONEST and TOTAL, FULLY DETAILED explanation on Digital Cameras Sensor Sizes and Lens kits.
Thank you very much, lot of greetings for sharing it!!!

Genny lamerveille says:

Why everytime someone say, if you want ti know more about "X" i have made a video about and share the link under the video…and oups. No links. Every time.

Nicolaus Uhlmann says:

Thanks so much again ! Informative , enjoyable , and most importantly well said ! 🤗

Raymond O'Toole says:

This video came at a perfect time for me. Cheers.

Justin says:

It seems appropriate you are in a cemetery… Because I really wish this sensor size comparison stuff would die.
(Not knocking your video or work, specifically, I've just seen this conversation go on and on and on and it's generally a bit of a bore)

Chris Baum says:

Great video, as always! Another question worth considering is, what kinds of photos do you plan on taking? If you’re planning to shoot wildlife or sports, for instance, you may want to take advantage of the extra reach that the crop factor gives you. A 300mm lens on a micro 4:3 gives you the equivalent of 600mm on a full frame, and you can get it for a fraction of the cost. This is why even some pros use APS-C or 4:3 cameras for long wildlife shots. But maybe this is the only type of photography for which this consideration really matters? It’s true that at the other end of the range, the crop factor works against you (14mm is a very wide angle on full frame, but the equivalent of a modestly wide 28mm on a 4:3), but manufacturers do a lot to account for this by offering significantly wider focal lengths as “standard” (by which I mean a normal-use kit lens, as opposed to special-effect such as fisheyes) for smaller sensors than they do for full frame. But at the long end, the advantages of a smaller sensor should
not be overlooked!

Paul Downey says:

Best explanation I’ve seen yet and I’ve seen LOTS these past two years! Thanks. 👍
