content: Hi,all i wonder if anyone can give me the answer to the question,1. Does this camera auto negioate with the monitor what resolution it can connect to as I have old trusty dell 1920x1200 monitor that can do HDMI 1080p input automatically, Why I just want to be able to connect to a HDMI 1080p monitor , without having to configure anything turn on and go etc. as the camera also supportes 4K which i don't want to use.example of below eakins/lapsun do they same camera as wellhttps://www.aliexpress.com/item/1005006624804675.html?spm=a2g0o.productlist.main.5.5e6f5c9ex9MaJQ&algo_pvid=65419ee3-d9c4-4b3a-a5d7-7d304551d927&algo_exp_id=65419ee3-d9c4-4b3a-a5d7-7d304551d927-2&pdp_npi=4%40dis%21AUD%21388.87%21388.87%21%21%21258.18%21258.18%21%402103252e17212714777257949e0dd4%2112000037856038826%21sea%21AU%210%21ABX&curPageLogUid=5wAeDAzU9a2L&utparam-url=scene%3Asearch%7Cquery_from%3A2. Would i need an addtional 5mm spacer on-top of the 0.5X focus adjustable microscope C mount adapter to work I already own that adjustable adapter. i use the 0.5x lense underneath the opticsI asked questions to them on message to multiple vendors, they dont't replay or go off on tangent that i need a microscope and never answer the question , camera -> HD monitor (auto negioate resolution output ie HD 1080p ).thksJames

content: For roughly the price I see for the linked camera, 284,42€, you could, with a bit of patience and tinkering, buy a used micro four thirds system camera with an HDMI output and adapt it for a 1X photo port if the microscope offers that. That would give you six times the sensor area which would not hurt at high magnifications. Just a thought if you like to test and refine tools.

content: thksI looked at a canon with HDMI on the top 3rd port , I do have an old canon that has composite output, but want the auto-zoom leave and forget,Is their lenses/adapters out their ? that do can to autofocus a SLR to the top of the tri-microscope port it has the large port 38mm that accepts the c-/cs adapters, when looking up at monitor and then through bino sights.J.

content: What model microscope do you have?A 38mm ISO photo port can project directly on to a camera sensor which often gives you the best images. Attached is a drawing of Nikon's C-mount adapter that shows the geometric problem you would solve. This particular adapter will just manage a 4/3" sensor with no or very little vignetting (see the second attachment shot through a D10NLC, a close copy).EDIT: I should add that you may find it easiest and cheapest to find a camera that matches the photo port rather than magnify or reduce the photo port image to match a camera.

content: J,i did a google D10NLC, a close copy, this website came up with different adaptershttps://webstore.diaginc.com/Microscope-to-Camera-Adapters-s/41.htm,x2.0 on the sensor size APS-C and APS-H sensors used in the Canon EOS Rebel, 50D, 60D, 7D, 1D.The full frame APS-F sensor size is supported by the 2.5x version.so good 2nd hand canon which does not have issues on burnout or sensor shutting down overheating be the next problem. unless its with a mirrorI have an old canon 450 EF-S , i use alot of EF series fixed focal lenses with it for better images in panaramics 'optics', anyways its been around the world a few times and under waterso that be x2.0 on there site. i hook it up to my monitor and see what the composite output be like just for funthksj.

content: Quote from: JimboJack on July 18, 2024, 03:15:10 amConnecting a 1080p monitor to these cameras usually is easy. I had one Eakins and one very similar 4K-cam and they both are quite picky establishing 4K-connections over HDMI.Anyhow, I like the value/price ratio of these devices a lot, they are great tools. But getting AF, 4K and 60fps in this price class with reliable operation just seems too good to be true.

content: If you want to think of it this way, what I am suggesting is making the microscope, the camera's objective, a somewhat large, ungainly objective, but from the camera's perspective, just another, manual focus objective. For this, a mirrorless camera with focus peaking would be good. Sixteen or even twelve megapixels could be enough but I would need to know more about the microscope and what you will be shooting.

content: thks for the info on the best HDMI camera autofocusi look at upgrading to SLR/DSLR later on 4K version ,but i will buy an adapter for my current SLR if i need to take smilies of silicon life through the eye piece
