Why 20 megapixels if 5 are enough?

Why are there 20-megapixel cameras for microscopes if everything over 5 megapixels is wasted?

(1) Cameras with fewer megapixels tend to be older, therefore more expensive even if marked down simply because their original MSRP was sky high due to them being cutting edge tech at the time. Cameras with more megapixels tend to be newer, therefore cheaper due to their tech being now mature and commoditized.

Thank you so much. This is very helpful Mr. Hunter. It looks like I'll be buying the OMAX 5MP USB 3.0 C-Mount Microscope Camera since its dynamic range and SNR are far better even than the higher MP cameras, even though its a lower price.🙏

@Bobbysoxer2

It would be helpful to actually see what is actually seen through the scope with low and high megapixels.

I've tried my Canon 77D connected with Eos utility, with the lens you recommend, with no lens strait sensor, and with the 10x eyepiece. All don't compare to the swift 8mp, think it was $80. I use the SW380T with 4x,10x, 20x plan, and the 40x objectives. Why all the hype about using a dslr, when like you said in this video that 8mp is enough. There's only one time that the dslr is better, and that's using the 4x. Has to do with pixel size and magnification.

@f.k.6151

It is more complicated than that. A 5mp sensor 1/4 the size of a 20mp sensor are providing the same pixel density. And it is the size of the pixels and how many there are within a particular range of sensor area that should be compared with the optical resolution.

@almikell5500

I am going to look for one of your videos that directly addresses the issue of speed I know that you enjoy playing with a little creepy crawlies.. with frame rates below 1/30 of a second.. thank you..I really appreciate your work.. I'm a teacher.. my students love microscopes

Hi there,

@carlhunsinger9638

The reason is simple. Sensor manufacturers do not want to make 5MP sensors. Nobody would ever buy them. If you have a larger sensor with lots of megapixels, look into pixel binning.

@oni2ink

I got an SC1803R 18MP camera new for "cheap" (half the price, so about 200€) and indeed the maximum resolution is not really usefull.

@MarieChardome

interesting, although i don't understand all this yet. so at my lowest level, i decided to have fun comparing pixels of paper, cd, book covers, wrapping etc under my sf10 stereo 🙂

@weekenddistractions

I wonder how anti-aliasing filters put onto the sensors impact the effective resolution. Maybe that's a reason to go for a much higher resolution sensor that doesn't have such a filter?

@pishyenaz

Hi, I'm new into microscopy and I have a DSLR Nikon camera and I'm planning to purchase bio blue compound trinocular microscope from euromix. Can you guide me through how Can I connect my microscope to my DSLR camera? Which adapter should I use and where to purchase the adapter? Thank you and appreciate your answer

@lotharmayring6063

get a 4k webcam for some bugs and change the optics and you have a perfekt microscop camera and dont use such monster cameras which is shown in the video here for microscopy

@sanabriafoto

I think the higher megapixel count serves for print reproductions. Sometimes the world forgets that there's a life besides the displays. A 1mpx or even 5mpx aren't enough for high quality printing. I've seen too many science books and articles with thumbnail size pictures, maybe the scientists community doesn't care about science diffusion into the general audience.

@michalbystricky8889

"megapixel" is the last number we should look at. There are more interesting camera properties than max pixel resolution. Eg. global shutter, short exposure time (for living organisms) etc. Personally I use RPi HQ GS camera with just 1,6Mpx but with global shutter and 30 μs minimal exposure time.

@geoffgeoff143

Dynamic range is more important than megapixels.

@minibigs5259

Are there any really good reviews of not shit cameras? I vuess due to cost, everybody likes to do reviews of shit cameras.....but nobody really does xvyvz of potentially decent cameras?
