Dear all,
I had in a plan to purchase few URSA Broadcast cameras but after I saw two reviews on B&H I really become very worried about this two reviews:
1. "First issue ... I have a great 1.8 Fujinon 2/3 HD ENG lens that gives me pristine images on my Panasonic ENG camera. But because of the long B4 mount on the Ursa Broadcast camera I seem to be losing about a stop and a half to 2 stops of light, maybe more. They don't tell you about that in the description. I thought I might be able to make that up by using the Gain but no way. The camera is surprisingly noisy even at 0 DB and just got worse when I tried to compensate for the light loss by adding 3, 6, and then 12 DB of gain. All I got was increasingly worse grainy imagery. I tried in HD 1080P and then in UHD 4K and the grain was bad in both cases. Worse still, the moment I went to 4K, I got this Cross Hatched footage. Unacceptable. I film the performing arts for a living and an ENG Camera is usually perfect for me, so I was extremely hopeful about the Ursa Broadcast but there is no way it could handle even a touch of underexposure let alone the low contrasty light conditions I work in (Black backdrops and wings on stage). I can't imagine how this could be acceptable to a news organization working in the street at night. Unless they lit everything. So.. i'm very disappointed. Not sure if it was just this unit, or if it's inherent in the Ursa. I should have waited to see what others said when they bought it."
2. "Love the URSA line Blackmagic is introducing. However, the B4 mount seems to cut out about a stop to a stop and a halfs worth of light when it finally reaches the sensor. And 12db if gain will 100% be too noisy to use.
Film profile helped a lot with this issue, but still not too nice. If youew working in a space with plenty of light, then by all means go for it. But if, like me, you don't always get that light....maybe keep looking for your affordable ENG."
After those two reviews, I have doubts about purchasing this camera
Is there any comment on this or is this fixable or not?
primarily, I am concerned regarding losing stops of light witch is really unacceptable and also how is camera performing in low light environments?
