content: Hello guys..please help me decide which camera is better to buy now..Which sensor is better inside.I bought AmScope 7X-45X Black Simul-Focal Trinocular Zoom Stereo Microscope Headhttps://www.aliexpress.com/item/32995863371.html?spm=a2g0s.9042311.0.0.43b34c4dACamera i want buy is in links below.. 3rd option is Autofocus 1080p 60fps SONY1.https://www.aliexpress.com/item/32906410173.html?spm=2114.12010610.8148356.24.3855b192.https://www.aliexpress.com/item/4000243884703.html?spm=2114.12010610.8148356.4.3855b197bixcaU3.https://www.aliexpress.com/item/32832761964.html?spm=2114.12010612.8148356.2.5facfc562NrAdnthanks

content: I think you are asking the right question: What is the right sensor in the camera? On a trinocular microscope you need a camera that can capture a high quality image with a modest amount of light i.e. the same light you are using to see with your eyes.If the sensor is not sensitive to light then you will end up spending a lot of time and money on illumination problems and you will also make the light uncomfortably bright for your eyes. This happened to me with the Eakins IMX290 camera which I don't recommend for a trinocular scope.Your option #3 seems to also have the IMX290 sensor so my guess would be that this is not a good choice. Hopefully one of the others will be a better choice.Please report back what you find out! I don't know what a good choice for 4K is, myself I settled for slightly below 1080p with a RaspberryPi with HQ camera for <$100 which performs much better than the IMX290 on my microscope (Eakins clone equivalent of your AmScope.) I would like to upgrade to 4K one day and I'll be interested if someone knows what a good choice is.

content: Have you considered an adapter for using a DSLR with the microscope? Most modest DSLRs have good low light capability, large sensors, live view and pretty good video capability, and the ability to capture very high resolution still shots.Best,

The 1080p camera had better response because it's easier to process 1080p than 4K.he speak about new 4K camera in me option 2

content: Quote from: jaaa1976 on October 08, 2020, 09:00:49 pmMy macro photography equipment is centered around full custom developed setups, lens and such which can do image stacking (and stitching). I don't use microscopes, but custom built fixtures to hold the camera/lens assembly and allow computer controlled image stacking (for increased DoF) by use of a linear stepper motor driven precision rails like shown below.All this has evolved for a long time into being able to create Giga-pixel images of custom chips we've designed. These setups are intended for stacking (and stitching) and not specifically designed to support video, but can do video.Generally you can find adapters for most popular DSLR cameras that will allow an interface to your microscope, all my stuff is Nikon based.Best,

content: For low cost, I would look at using theRaspberry Pi 12.3MP Sony IMX477 camera modulebut the Pi does not get full speed out of the sensor due to having only two of four possible CSI lanes.Camera boards have literally doubled or tripled in cost out of china the past two years, and now I see many "not for sale to Canada". Really, only one store- ELP selling them. The pandemic is supposedly causing shortages for webcams. A lot of specs are fake i.e. numbers for what the image sensor is capable of, but you get much less with the compression engine and USB or HDMI interface. So be careful the specs are not always what is advertised.The newest4K 8MP Sony image sensorsare IMX415 and IMX485 I believe.
