Product Highlights
  • For Lenses With Apertures of f/1.8-2.8
  • Manual Focusing Through Viewfinder
  • Precision Focusing in Low Light
  • Decreases Focus Around Subject
  • Installation Tool for Handling

This Ef series Super Precision Matte Ef-S Interchangeable Focusing Screen from Canon provides easier manual focusing through your viewfinder on subjects in low light when using lenses with a wide aperture between f/1.8 to f/2.8.

This "S" type focusing screen works by decreasing the focus of the slightly out-of-focus areas around your in-focus subject for a sharper contrast.

Compatible with Canon EOS 40D, 50D, and 60D
Not recommended for ordinary zoom lenses with maximum aperture slower than f/2.8 as the screen will appear dark and grainy
Focusing screens are delicate and should only be handled using the included gripping tool for installation

      After using the EF-S Focusing Screen for about a week and making a side-by-side comparison with the EF-A Screen (the one that comes with the camera) these are my observations:
      - With f/2.8 or faster lenses you can appreciate the improvement in the out-of-focus areas. Not so much with f/4.0 or slower lenses. However, the effect is much more pronounced with f/2.0 and faster lenses; at f/2.8 it isn't as dramatic as I expected, but still makes focusing easier anyways.
      - It really darkens your viewfinder. Besides being recommended for lenses not slower than f/2.8, I've find the screen usable up to a f/4.0 lens. At f/2.8 the viewfinder already gets sensibly darker than the EF-A screen which makes a bit harder to photograph in low light environments. At f/1.8 the darkening is almost negligible.
      - Works OK for macro with a f/2.8 lens, but will darken considerably with extension tubes. I can't say if it darkens less or more compared with the EF-A, but you can have a harder time trying to focus it the scene is already too dark.
      - Exchanging focusing screens is very easy and can be done in the field with the supplied tool.
      - After replacing the focusing screen, you must remember to change the corresponding custom function on the camera or your metering won't work correctly.

      I'm not giving it 5 stars because at f/2.8 the EF-S screen isn't that great (sadly, the most lens I own are f/2.8, despite f/2.8 being and officially supported aperture. For the time being, however, I'm keeping it installed on my camera because I'm not too fond of the EF-A (which I may replace with a EF-D screen just for landscapes at night/dawn, where a brighter viewfinder with grid lines will be more useful than the EF-S).

      Its super easy to install with the supplied tool
      The main difference with this screen is that the DOF is changed greatly, giving you a much better sense of final DOF instead of a artificially increased DOF from the micro lenses on the std. screen.
      Problem is that the screen, with the prism, do not transmit as much light, and so with F2.8, 3.5, 4, indoors, you can not see your subject. Its very dark and not worth it.
      - Awesome for landscape, macro, and portraits
      - Not so great for indoor weddings, flash, and other low light situations, or with F4 lenses.

      Somewhat better than standard for macro

      Comments about Canon Super Precision Matte Ef-S Interchangeable Focusing Screen:

      This is replacing one that I've lost and used for macro.

      The enhanced focus fall-off is good for setting up a perfect focus in a macro setup - but it comes at a cost of being able to locate the subject at all (which can be a challenge >2:1 with moving subjects). That's not a fault of manufacturing or design, just a limitation of physics.

      It seems to pick up dirt more than I'd expect too, but if you manage to keep track of your original one you can at least remove it to clean it simply with the provided tool (never directly touch the screen).

        I had to have my 50D go anywhere camera cleaned after 2 trips to the sandbox so I decided to try a different focus screen. I do a lot of shooting close up and this screen has better clarity wide open. I really don't see any huge difference light wise stopped down either. Be sure and go into your camera functions and change the settings for this screen.

              It's a little darker than the standard focusing screen so remember choose the ef-s focusing screen in the custom functions in the camera.

              • Traveling

              Comments about Canon Super Precision Matte Ef-S Interchangeable Focusing Screen:

              I'm using this only with f/2.8 and f/1.4 lenses. For the first time in many, many years, I can now manual focus very well in most normal lighting conditions. Helping a ton with composition of close and medium range shots, and quite a bit in more difficult macro situations.

              My viewfinder is not signicantly dimmer than before, but only what is sharply focused actually looks clear (whereas on the stock screen, things were deceptively "clear" whether in focus or not).

              I do notice that towards the edges and corners apparent focus is softer, which is a little disappointing, but, overall, this is a big, big help. I'm glad I have it, as it adds much needed flexibility to composing (without having to rely on an AF-point and then re-compose).

                I use this specifically with the Canon 65mm MP-E (which is manual focus only) so it was great to have this ability to make it easier to focus. I am, however, thinking about getting the Katzeye focusing screen because you can get more options added to it... albeit at a much higher cost and wait time.

                  Despite some negative reviews, the EF-S is a breath of fresh air compared to the camera supplied EF-A. I just couldn't consistantly manual focus with the EF-A...and the EF-S made a huge difference. I use 2.8 and faster lenses...so I can not speak for the slower lenses. If you are having a hard time with manual focusing with the SF-A, take the plunge.

                    I find many situations where auto focusing was unreliable or inappropriate due to low light level or special need. The stock focusing screen did not provide clarity for manual focusing either, and the EF-S focusing screen was purchased with the intent of improving accuracy of manual focusing in these situations, especially in low light. The mat finish does improve manual focusing accuracy, although not to the degree that older, pre-autofocus Canon focusing systems did.

                    I think this is a necessary upgrade for your camera if you use high-speed lenses often. It makes a slight improvement to focusing, but not that much. I was a little under-whelmed when I started using it. It could be better. The darkness through the viewfinder is much more noticeable as well using apetures smaller than f2.8.

                        With my two Zeiss ZE lenses, I've been learning the art of manual focusing. I'm mainly into cinematography, but I like to snap the occasional still.
                        This screen fits a 60D.
                        It is easy to install, but it does require a bit of confidence and dexterity.
                        It seems to help, but not by a lot.
                        Back in the day, I had a similar screen on my OM-2 and that seemed to help a lot more. And well, my eyes are not quite as young anymore.
                        Fortunately, for critical focusing, live view is awesome.

                              I might have to switch back and forth a few times to really notice. I didn't have the original focusing screen very long to compare. I made the immediate jump to this one. I do have a 50mm f/1.4 and I guess it helps at some point. What doesn't seem to help is if you have accidentally turned the diopter dial on your Canon.

                              Can say that it was easy to install.

                                This has really helped me focus in the manual mode. It makes focusing in dim lighting much easier.

                                        I bought this screen for my Canon 60d because I was getting too many "almost but not quite in focus" pictures using a Zeiss Distagon 2/35 lens.

                                        It works as advertised and greatly improves your ability to focus manually.

                                        I gave it 4 stars because it is not recommended for lenses with a maximum aperture above 2.8.

                                            Comments about Canon Super Precision Matte Ef-S Interchangeable Focusing Screen:

                                            I am using mine with Zeiss Lenses and it helps bring about the pop. While it does not have the split screen for even easier focusing I feel that is a great compromise for the price. Like the other commenters stated, its super easy to install and does get a bit darker for f/4 lenses. If you are using any fast glass/manual focusing/adapted glass this is the way to go.

                                            Works great. Recomend it with fast lens.

                                            I own my 50d 4 days and then purchased this. I now almost exclusively manual focus everything. I have been shooting my son's soccer games all with manual focus. I can now focus faster that AI Servo on a moving subject. Comes with great directions for installation.
