Alphatron EVF-035W-3G overview

  • 1Description

The Alphatron Broadcast Electronics EVF-035W-3G Electronic Viewfinder features a 3.54" LED-backlit LCD and displays 24-bit RGB at 960 x 640 resolution in a 16:9 aspect ratio. Brightness is at 500 nit and contrast ratio at 1000:1. The viewing angle is 160 x 160°. The unit comes equipped with an adjustable diopter and a manual lens shutter for protection of the LCD. A 6" D-tap cable is included.


Connections consist of SDI and mini-HDMI inputs and outputs, a phone jack for calibration and a USB port for software upgrades. You can loop out from both SDI and HDMI and perform conversion out from HDMI to SDI. (If your camera has a mini-HDMI port, like many cameras do, then you will need a mini-HDMI to mini-HDMI cable to connect the camera to this viewfinder.)

Adjustable features include Brightness, Contrast, Color Temperature, Sharpness, various Scan modes, Markers, User Aspect Zoom, and Blue Gun. Professional features available are 3G Level A/B, Audio Meter, Time Code, Range Error, Zebra, Luma y' Zone Check, Focus Assist, and Internal Colorbar and Pluge Pattern.

The viewfinder has a lightweight magnesium housing and can be powered by an optional battery or DC power supply.

Note: You can upgrade this EVF with Waveform & Vectorscope functionality via a free V0.6 firmware update from Alphatron's website.

    Alphatron EVF-035W-3G reviews

    EVF-035W-3G Electronic Viewfinder is rated 4.3 out of 5 by 14.
    Rated 4 out of 5 by from Great buy.I use it on URSA mini 4.6 Gave it a four star, because I know no better. This is my first EVF and have nothing to compare it to. I have the URSA mini and needed a solution for shoulder mounted set ups. The BM EVF has stellar reviews but was a bit beyond my budget especially because it was designed to be proprietary. I have other cameras and needed something that can play well with other cameras. And it came in at almost half the price. Picture is good, has focus assist, exposure assit. I tend to leave them off on the UM and use it for framing and viewing overlays. The other tools I use the onboard LCD or atomos shogun which is much better than both for that.

    Rated 5 out of 5 by from One of the best One of the best EVFs I've owned. Pros: -Amazing display. -Great features -Plenty of custom options -SDI/HDMI compatible. -Lightweight (without battery, P-Tap power supply) -Sun-protected in case you forget to close the shutter. Cons: -Larger than expected- not much of a con for me, but compact seems to be the trend and it could be for some. -I find the button arrangement on the side odd, seeing as 2 is placed above 1, and 4 above 3...if that doesn't make sense, look at the photos. But I'm nitpicking at this point, it functions wonderfully!

    Rated 4 out of 5 by from Highest res/bad diopter/HDSDI-yes I have used this with a Canon C-300 and Canon 5D Mark III.The resolution is what I needed. It's 1/4 of a 1920x1080 signal.I was disappointed with the diopter. No one else mentioned this problem. I need reading glasses close up, but only a 1.5. But this viewfinder diopter did not allow me to focus on the screen. Even the cheapest viewfinders allow this. My solution was to remove a lens from reading glassess and affix it in front of their lens. Presto! It works! Can Alphatron produce this viewfinder with different lenses? Mine was a $10 fix but still annoying.I totally appreciate the HDSDI input. This is realtime with no lag. The HDMI input has a bit of lag like any HDMI. I really think they got cheap on the HDMI mini connectors. Why not just use the full size HDMI connector? I do like the pass through from HDMI to HDSDI. This allows me to use my broadcast production monitor with my 5D Mark III.The menus could use further refining.Avoid buying the Alphatron mount. It worked fine until it broke. A major design error...I really like the corner Waveform Monitor. The Vector scope is of limited use at this size. But overall a useful feature.Having said all of this, it is the closest thing to the viewfinder on my PMW-350-Still the best.My 4 stars is because it is still the best third party EVF as of May, 2013.

    Rated 5 out of 5 by from Almost perfect... so yes - great buy No such thing as a perfect camera or evf or any machine. Bought the Blackmagic URSA mini and needed an evf solution. The one for the camera has great reviews but is built for the URSA line. Meaning, it needed modification to work with other cameras. Cost too. I have HDMI and SDI cameras. So, this was perfect. Price was right. Has exposure and focus assist tools. Picture is good. I can't compare to anything as this is my first ever EVF. But I have used many camera screens (Started with the awefull DSLR screens) and this is pleasing. And it's future proof in terms of cameras I can buy. Unless they change Output formats.

    Rated 4 out of 5 by from solid choice for my F3 on my sony F3 - solid build. picked it due to SDI bnc's. sharp focus in the center of screen but seems to fall off juuuust a bit on the edges. peaking and zebras, etc. very useful.

    Rated 5 out of 5 by from The Cadillac of EVF's I held out on purchasing this for my FS700 for too long. I have no complaints with this product at all. It's super sharp and has all of the bells and whistles you can ask for. I especially like the little waveform monitor you can have on in the corner. The one bit of past criticism about this EVF was how it you left the lens shutter open outside on a sunny day, it would burn the LED in a matter of seconds. Alphatron has remedied this by adding a special lens that prevents this from happening. It's the best EVF out there, hands down!

    Rated 4 out of 5 by from very good great as a monitor and evf, have used the hdmi to sdi loop thru and works great. peaking focus assist works well.would prefer it was a little more robust and not as plastic

    Rated 5 out of 5 by from What I've been looking for. I use the Alphatron with my f3. I had a Zacuto evf before the alphatron and the Alphatron is FAR superior to the Zacuto.
