FS7: 5 reasons the URSA Mini is better than the Sony FS7

Magenta corners.
My first Sigma 18-35mm Nikon mount had significant dark/magenta corners on just the left side.
I sent it back and the new one is fine.
Had some older Tokina manual primes that went magenta in all the corners at wide apertures.

Based on my experience there is no way I will rule out that vignetting and color shift absolutely CAN come from the lens.

I suspect the current issue is more of a "combination effect". I.e., the Sensor is only just at the verge of injecting these kinds of artifacts, and paired with the right "wrong" lens you get the perfect storm and the artifacts come rushing in.

It's not the lens, its the QC on the sensor that is the issue. As usual.

It has to be, by the process of elimination. If the "problematic" lenses don't fit any given parameter and a (significant?) portion of the cameras don't exhibit any abnormalities either, it has to be the variance in production, probably in the sensor mounting.
 
Crap is indeed correct.

I was honestly stoked about the mini 4.6K. I knew it might have some compromise somewhere like a plastic feel, look ugly, or maybe a bad rolling shutter… but this sensor optics thing is in a whole other league of it's own.

Anyway, this will be my last post on the matter and this thread. It really doesn't matter anymore.

It didn't surprise me at all. It's BM we are talking about. I expected problems. But their excuse of it being a lens choice is hilarious. How can it be lens choice? When people get the magenta corners even without a lens in the camera by just holding paper in front of the mount?

Makes no difference for me though. I'm not buying one. I actually finally got rid of my FS7 too. Couldn't put up with it anymore. I'm now on the market for a new camera. But BM it won't be.

Come back in a year! Odds are reasonably decent this will all be sorted by then.

As is commonly the case with BMD cameras, don't pre order them, or even buy them when they first start shipping. Instead give it six months, or even a year, for everything to settle down and people to sort out the various problems.
 
However, and this is a big one. The EF mount is NOT right next to the sensor. it's 40 odd mm away from it. The emount is right next to it. So we should see huge issues with emount compared to EF but don't (sensor design?). And when was the last time someone on a C300 saw this?

To be honest that PL mount version would show it even worse if this was the case. So i don't know if there are any PL mount users seeing it.

IMHO i suspect it's a design issue. Either with the mount (and light reflections) or actually the sensor itself.

If as I'd suggested Blackmagic Design had used Kinefinity's KineMount (or similar), then if it was a problem with the mount this would then be a very simple and cheap fix! (well... relatively speaking, vs recalling all the cameras)

In a year's time the FS8 will no doubt be out and the FS7 will have been reduced in price considerably.

A long time to wait for a camera with a working iso of 200-400 in this day and age.

I thought it is an 800-1600 ISO camera? (it is the 4K version which is ISO 400 only)

And even after an "FS8" comes out, I doubt it will be offering raw as well or as cheaply as a fixed URSA Mini 4.6K would.

BMD cameras have surprisingly long lifetimes, can anything yet meet the price/performance of a BMCC/BMPCC even all these years later? Nope.

I suspect if the UM46K gets fixed quickly then it will be relevant in its niche for a number of years yet to come.


This is assuming what they are saying is true, and it's not a case of some sensors not being mounted properly.

That is why I said "if" ;)
 
Sounds like the FS5 will be offering raw at a lower price point already. Assume that will be the norm moving forward.

ISO numbers based on people's experience vs published on paper figures.
 
BTW, it could also be a double misalignment of both the sensor and the mount. Each could be millimeters off in all three dimensions and the worst misalignment would give the worst visuals while a camera made to specs would perform as it was intended. If correct, the fault would lie mostly on quality control, with some possibly spilling over onto the design and the construction.
 
Which is what I said pages back. Last bit anyway :)

Yes, I saw it. I thought I was adding to the discussion. Maybe not.

So, here's another tidbit from many years ago. Back in the late 80's, I was working at a retail outlet in Canoga Park (West San Fernando Valley in the LA County) and, one weekend, we were having an outdoor/parking lot sale. It was a reasonable idea in term of popularity but that day, it was over 100F in the Valley. And the parking lot was covered with dark asphalt. At about noon, one of the salesmen discovered that a cheapie Ericsson turntable we put outside simply melted. It was made out of low quality plastic and, after a few hours under a very hot sun, the center of the player became so soft, one could poke a hole in it with a finger.

The moral of the story is - this URSA 4.6 Mini body is also made out of plastic, right?
 
Where are the cameras made?

(but, this is a disaster for them ... off reviews, their QC is non-existent ... after stuff like this, customers do not come back)
 

Holy smokes. That was seriously brutal.

I think the strangest thing is on BMCuser, many are convinced the bad reviews are a conspiracy by Red, Arri, Canon and Sony users. I seriously doubt that. If the camera is good, it gets good reviews. Look at the FS7 and Canon cameras, most of the reviews are positive because by a massive margin the single most important thing is for the camera to work. Everything else is secondary.
 
I guess when you buy from a company calling themselves Black Magic Design, you'd better believe in magic!

Last year, I was considering the URSA myself, but spent two hours reading their forums and got a bad feeling about the camera. I'm sure glad I stuck with tried & true Sony. For all the niggling little things we complain about, the Sony just works and at the end of the day, you get paid and have a happy customer.
