The Canon EOS 800D on the microscope – a practical test

cannon dslr front

Canon’s EOS 800D DSLR camera was released in April 2017 as the successor to the EOS 760D.

The display is an important aspect when it comes to installing a camera on a microscope for image acquisition, and the EOS 800D does not disappoint in that respect: it features a TFT LCD touchscreen panel with a display diagonal of 7.7 cm (3.0’’). The screen can be pulled out from the body by 180 degrees and rotated through 270 degrees, which is a great advantage over fixed screens in terms of efficiency and ergonomic characteristics.

The image shows the Canon EOS 800D attached to a Zeiss photo tube using one of our LM digital adapters with a plan achromatic optical system. The practical advantages of the vari-angle screen are particularly noticeable in that configuration.

The Canon EOS 800D weighs 531 grams (body only with battery and card). As only the body is attached to the microscope, it is exactly that weight which is relevant in photomicrography. For using the microscope’s eyepiece tube, a more lightweight camera – such as the Canon EOS 200D – would be even better, but with our LM adapters, fitting the EOS 800D to the eyepiece tube is an easy feat. The modular construction of our adapter solutions facilitates maximum flexibility and easy conversion to microscopes from different manufacturers at relatively low additional costs.

The EOS 800D has an APS-C sensor with 24 megapixels. Its image processor is capable of shooting at a maximum of 6 frames per second. Images can be stored in JPEG and RAW format. The camera also includes Bluetooth, WiFi and NFC for added connectivity options and has an HDMI mini OUT terminal. Movies can be shot at Full HD. If higher resolution (4K) video is required, a Sony Alpha 7R II or 7R III should be used.

ISO sensitivity can be set between 100 and 25,600, which places the EOS 800D in the mid-range, similar to the EOS 80D. The camera is thus also well suited for low-illumination techniques such as fluorescence microscopy.

All basic functions that are essential for photomicrography – manual ISO adjustment or deactivating auto shut-off – are supported. Disabling the auto power-off setting is especially important when the camera’s internal battery is charged with an AC adapter or when the camera is used for longer presentations.

We tested the EOS 800D on a PC using the proven Canon Utility software which is included for free with the camera.

The computer detects the camera without any problems.

Now, different settings can be configured in Live View, such as

The following steps are shown:

Overall, the software is very well structured and easy to use.

In addition to its EOS Utility software, Canon also offers an app that connects mobile devices to Canon cameras. We used the Canon Camera Connect app to connect to a tablet. Again, the camera – after enabling its built-in WiFi – is detected immediately.

Using the tablet as a remote shutter release works like a charm.

It is also possible to change the ISO settings.

The menu displays additional options, such as image rotation, Live View rotation or mirroring as well as magnification and touch AF.

Conclusion:

Thanks to the powerful Canon Utility software, Canon’s new EOS 800D DSLR camera is a great choice for use with a microscope. Additionally, Canon’s Camera Connect app offers several interesting options for working with a smartphone or tablet. The EOS 800D comes equipped with all the basics you need to create truly satisfactory microscope images. The absence of a built-in HDR mode is the only drawback – if you want to shoot 4K video, cameras like the Sony Alpha 7R II or 7R III would be a better choice.
