Canon 550D 600D 650D T2i T3i T4i Focusing Screen

KatzEye™ Focusing Screen for the
Canon® 550D/600D/650D/700D (Rebel T2i/T3i/T4i/T5i)

General Information

The KatzEye™ focusing screen for the Canon 550D (Rebel T2i), Canon 600D (Rebel T3i), Canon 650D (Rebel T4i), and Canon 700D (Rebel T5i) is a laser matte with a split prism circle and a microprism collar, very similar to the one you would find in many classic SLRs. It is a direct replacement with no modifications required to the camera at all. The split prism with microprism ring is a great combination for focusing in a variety of situations and the screen will have no effect on the functioning of the autofocus sensors of the camera.

Viewfinder Markings

The standard KatzEye™ screen for the Canon 550D/600D/650D/700D does not have the focus area rectangles marked like the original screen. In addition, the red dots in the viewfinder will not light when the AF points are activated. For those users that wish to have the focus area rectangles marked, this available as an option. If you want the AF area rectangles, please be sure to select the appropriate option below when adding the screen to your cart. Please be aware though, that even with the rectangles marked, the red dots will still not light. All other viewfinder information displays function as intended. The lack of the indicator dots and/or rectangles has no effect on the camera’s ability to autofocus. In addition, the LCD on the back will allow you to select your focusing point and the green light in the viewfinder will blink for focus confirmation.

Metering Information

The KatzEye™ focusing screen for the Canon 550D/600D/650D/700D has little to no effect on light metering in Evaluative or Center Weighted metering modes. However, because of the presence of the prism, Partial and Spot metering modes are affected, depending on the lens in use. Suggested exposure compensation values for each of the metering modes are as follows:

Aperture Evaluative Center Weighted Partial Spot
1.4
0
0
0
0
2.0
0
0
0

2.8

0(S), -0.3(O)
-0.3(S), -0.6(O)
-1.6(S), -2(O)
-4.0(S), -4.3(O)

(S) = Without OptiBrite Treatment
(O) = With OptiBrite Treatment
0 = No exposure compensation required.
NR = This combination is not recommended. Use an alternate light metering mode or manual exposure settings.

Note: These exposure compensation suggestions are a recommended starting point only and actual results may vary depending on conditions. Users are advised to take a test photo and check the histogram before beginning any critical work. Apertures indicated in the above chart are the lens maximum aperture as indicated on the lens body and are not affected by the actual aperture chosen for a given photo.

Metering test results presented are based on testing of the 550D model. While results are expected to be similar for the 600D, 650D and 700D, users of these camera models are strongly encouraged to take a test shot and check the histogram before beginning any critical shooting.

The “Plus” Prism

The KatzEye™ focusing screen for the Canon 550D/600D/650D/700D is available exclusively in the KatzEye™ “Plus” version. The “Plus” version has a unique prism design which delays the prism ‘blackout’ phenomenon until well after f11. Ordinary split prisms will black out by about f5.6, rendering them difficult to use with slower zoom lenses, teleconverters, or in extreme macro photography... but not the KatzEye™ “Plus”. More information about the KatzEye™ “Plus” can be found here.

Installation

The KatzEye™ screen is a direct replacement for the original and no modifications to the camera are required. The installation requires no special tools or skills, but it does require working in tight spaces. If you are not confident in your vision or dexterity, professional installation might be advisable. For those users installing the screen themselves or for those taking the camera to a local shop, a detailed installation guide, with plenty of high resolution photos, is available for download here.

Since the KatzEye™ screen is a direct replacement for the original, any competent shop should be able to handle the installation and the original screen can be reinstalled at any time, should you so desire. If you want us to install it at KatzEye™ Optics, we are happy to complete this service for you. Please see the Installation Service page to order installation with your focusing screen. Installation service at KatzEye™ Optics costs $65, plus the cost of return shipping of your camera.

Brightness Enhancement

Like all screens made by KatzEye Optics, the Canon 550D/600D/650D/700D screen can be OptiBrite brightness enhanced for the ultimate appearance. The OptiBrite treatment has little to no additional affect on light metering in the Canon 550D/600D/650D/700D beyond the effect caused by the prisms (described under Metering Information).
