Quick and dirty low light test at DVinfo.net

Not scientific at all, I was just playing with the camera and thought I'd do a quick comparison...

Nice Paul

I also lock both cameras at 3200 ISO as after that the noise is just not acceptable. A comparison between that 35mm and the stock lens would have been nice too so you could show the difference between an F4.0 and an F1.4 in very low light. I personally never go lower than F2.8 on my standalone zooms otherwise DOF becomes a major issue ... My Nikon DSLR's are equipped with a 17-50 and an 11-16 both F2.8 constant and they are quite useful lenses when used on the EA-50

Was that an eMount lens???

Yes, it was an E-Mount version of the Rokinon 35mm Cine lens...I'll try to do a comparison this weekend if I have time. Overall, I'd be comfortable shooting with this camera up to 3200 ISO if needed (I would never go that high on the 5Dmk2)

Hey Paul

Thanks ... I was wondering if you were maybe using a preset on white balance as the dark areas of the image were sorta brown rather than black ..even at 3200 I find the blacks seem to stay nice and crushed unless of course you were using a custom picture profile. That sounds like a nice lens but I really struggle using primes so I resort to slightly slower constant zooms like F2.8 and still get nice images with the flexibility of being able to change focal length too!!

I used the "Glencolor2" picture profile for the Sony FS100 found here:

G-LOG Picture Profiles for the FS100 – version 1.0 | Frank Glencairn

...but I tweaked color a bit since it was designed for the FS100 and not the EA50...as far as WB I think I had it set to auto for this, I usually dial it in Kelvin but guess I was lazy that night lol

Also, I should note I didn't record this as native AVCHD in camera to SD card, I recorded it externally from HDMI to an Atomos Ninja at ProRes 422 HQ...so the reduced compression of ProRes vs AVCHD and added color space of 4:2:2 may also have affected the outcome of the image
