Canon 0848B001 overview

  • 1Description

This Ec series Super Precision Matte Ec-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 1D Mk II N, 1D Mk III, 1D Mk IV, 1Ds Mk III, and 1Dx
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

    Canon 0848B001 reviews

    Super Precision Matte Ec-S Interchangeable Focusing Screen is rated 4.6 out of 5 by 12.
    Rated 5 out of 5 by from Indispensable for shooting wide open This focusing screen has worked perfectly on my EOS 3. I shoot at very wide apertures on this camera almost all the time and this screen has been an incredible help in finally being able to focus exactly where I want. It was super easy to install too.

    Rated 2 out of 5 by from Shows focus costs brightness The Ec-S focus screen does indeed show depth of field more accurately, especially when used with fast lenses. However, it costs viewfinder brightness, and not just a little. By f/2.8 the viewfinder appeared a stop darker than when using an Ec-C IV screen, past that it only got worse. In low light I found that any gains from being able to see the depth of field better were countered almost completely by the viewfinder being so dark that it was hard to see anything.

    Rated 5 out of 5 by from Excellent product and performance As a professional wedding photographer I have come to expect the highest in performance from my Canon pro gear. This focusing screen is yet another example of a world class product from Canon. The light transmission is excellent, enabling an instantaneous and precise focusing solution when used in very low levels of light. I am very impressed with this focusing screen.

    Rated 4 out of 5 by from Fantasic for manually focusing primes! I use this on my 1D3 with my Contax Zeiss primes for full time manual focusing. The screen takes about 1 minute to install so its great. However, if you have lenses slower than 2.8, you will get noticeable viewfinder darkness. I use my lenses wide open so its been great. Liveview is admittely sharper but lugging around a tripod is silly.

    Rated 5 out of 5 by from ECS focusing screen I shoot with manually focusing zeiss for Canon lenses, with the stock screen 30% of images were OOF, with the ECS screen 100% are tack sharp, you will miss shots without this screen, it is that simple.

    Rated 5 out of 5 by from Works great with fast glass. I use this focus screen as my primary on a 1D Mark II n. I find myself able to much more accurately and quickly able to manually focus. All of my primes are 2.8 or faster. I have heard that this screen is too dark for slower glass. I have yet to be able to see, but it does seem a bit darker than the standard screen. Using the included tool, installation is very simple. I am very happy with this purchase.

    Rated 4 out of 5 by from great product this screen makes it much easier to focus by making the out of focus area more noticable. also, with a f4 lens it is darker but still usable. I used the 70-200 f4L & the 17-40 f4L at a wedding where the reception was very dark but after a while i didnt notice too much difference once i got adjusted to the f4 lens being darker.

    Rated 5 out of 5 by from Must have for fast lenses I use fast lenses for all my pictures. I love the boken effect and with this new focusing lens you can accurately definte that space through the view finder. Installation is cake although the idea of replacing a piece of the camera so close to the sensor and mirror was scary.
