Epson announces mass production of the EVF found in the Leica SL Typ 601 mirrorless camera

the EVF inside the new Leica SL Typ 601 mirrorless camera is made by Epson
DC.Watch speculates that the EVF inside the new Leica SL Typ 601 mirrorless camera is made by Epson. This EVF is the best I have ever seen so far (see our Leica SL review) - the current EVFs used by Sony and Fuji are not even close. The good news is that Epson is now starting a mass-production of that EVF and hopefully other companies will be able to use it in their mirrorless future solutions (hear that Nikon and Canon?). Here are the details:

Epson Begins Volume Production of High-Resolution Ultimicron Panel for Electronic Viewfinders

Epson Ultimicron electronic viewfinder panel
New panel realizes world’s highest resolution for volume-produced panels for EVFs

Seiko Epson Corporation (TSE: 6724, "Epson") today announced that it has recently begun shipping its latest high-resolution Ultimicron panels for electronic viewfinders (EVF). The new panels boast the highest resolution among volume-produced products for digital camera EVFs*
Epson has continued to refine the performance of its Ultimicron panels with the aim of achieving the natural and beautiful images required by quality EVFs. Measuring 0.66 inches diagonally, the new Ultimicron boasts resolution of 4.41-million dots (SXGA+ (1400 x RGB x 1050)) - approximately double the resolution of conventional XGA products - and provides camera manufacturers with greater optical design flexibility, for example lens selection or magnification ratio. By expanding the color gamut by about 30% compared with existing products, Epson has allowed users to adjust the screen to their preferred color. These specifications translate into a natural viewfinder that precisely meets the needs serious camera users.


Name L3FJ63800C
LCD type TN mode, organic alignment layer
Color display system Color filter (RGB stripe)
Effective pixels 1400 x RGB x 1050 (SXGA+)
Panel size (diagonal) 0.66 inch (1.65 cm)
Pixel pitch 9.6 μm (3.2 x RGB) x 9.6 μm
Color space 98% of sRGB
Backlight Yes
Surface luminance 650 cd/m2
Displayable colors Approx. 16.77 million colors
*Based on Epson research as of November 2015.

    I checked that Leica out at the PDN Photo Expo, and that viewfinder looked like crap. It was super contrasty with buried shadows and blown highlghts. I’ll have to assume it was a setup mismatch, but why would you do that at that camera’s inaugural outing? The jury’s out for me on this.

    • johnny

      Maybe they did this in purpose. Higher contrast is better for manual focus.

      • longzoom

        So wrong purpose. With washed out highlights it is almost impossible to focus correctly.

        • malchick743

          Must agree, quite contrasty so to speak, even if the EVF is supposedly hi-res, it doesn’t feel great when looking thru…

          The other question perhaps would be the need to implement ultra hi-res EVFs. Are they really better then 2MP EVF? Do they drain more power than expected? What other technologies would be deployed to make the view more natural? etc. etc.

          • MdB

            You can apply log type profiles in camera which enables a flatter view, or you can at least on some.

            Having used just about all of them I prefer the contrast of OLED viewfinders to these TN panels.

      Meh, all EVFs are problematic. This one is pretty good. What’s bad about it is the processor powering it, which, like all EVF cameras, chops when things go dark.

      Interestingly, I’ve found it easier to manual focus with lower resolution EVFs, mainly because the area of highest acuity almost shimmers in rough pixels. When the EVF resolution gets too high, you can’t pick out individual pixel shimmer.

  • johnny

    It’s 1.47MP, not 4.4MP. These manufacturers should stop this RGB effective pixel crap.

    • MdB

      So we should probably stop saying 12MP and 16MP and 24MP and 36MP etc then?

      • johnny

        Only Sigma will count sub-pixels from their DSLR. Most 12MP,16MP,24MP or 36MP camera are actual pixels.

        • MdB

          No, they are the equivalent of ‘dots’ but instead of being in a RGB array they are in a RGGB array. Sigma’s aren’t counting ‘subpixels’ in that context either, or they all are, take your pick.

          • johnny

            Sigma does count subpixels. The SD1 was advertised as 46MP camera, but in fact a 15M ‘dots’ camera.

          • MdB

            Yes I’m aware of that but Bayer array sensors aren’t full RGB pixels either. Also you are mixing things around, the Sigma is a 15M ‘pixels’ camera, with 46M ‘dots’ so to speak.

          • johnny

            Dot or pixel, whatever. This thing is misleading. It’s supposed to be number of fully functional dots or pixels, not RGB sub-pixel counts.

          • MdB

            So… Just like megapixel counts then?

  • HD10

    This is good news and I expect to see this in the next generation of EVF-equipped cameras. I wish there was an industry standard so that upgradeable EVF will become a standard feature in most cameras.
