Just checking, Does anybody know
if the infra-red pollution problem is solved in the new
Sony PMW-EX1R?

Yeah it's pretty much you want a hot mirror/IR filter if you are shooting in heavy sunlight scenes. This is a problem for most CMOS sensor cameras...

Hello Thomas,

Recently I was also of the opinion that the Tiffen T1 IR filter was also a necessity when shooting with either the new PMW-EX1R or the PMW-350(K) models. This is not the case. Sony has apparently been successful in dramatically reducing the IR contamination in their new EX cameras without affecting the widened colour gamut in the red spectrum which was so ground breaking when the EX cameras first appeared in the fall of 2007.

In the comparison pictures in the first article below you'll notice that the Sachtler bag IR contamination is 95% gone in the EX1R shot and all gone in the 350K shot. And no T1 filter was used.

The Tiffen T1 IR filter cost is about $140.00 USD so I guess you could get one and see if the difference is worth it. But honestly? If I had an new EX1R I wouldn't worry about it.

I have an EX1R and it is a problem. I'm waiting on my cutoff (IR) filter

Thank you very much for all the response.
I'm planning to move from EX-3 to EX1r for reasons of size.
And with the EX-3 I always use an IR filter because its pretty tricky to shoot without one.
But because of the heavy coating it flairs easily.
So if the EX-1r solves all these problems that would be great.
Once its here I'll run a test an keep you posted.

Cheers,

According to Philip Johnston on this EX1R review, the EX1R does not suffer this problem.

Hope I haven't double-posted here. My first effort didn't show up.

According to Philip Johnston on this EX1R review, the EX1R does not suffer this problem.
He claims it has a filter in front of the sensor.

I hope he's right, it was one of the key points when I made the decision to buy the EX1R.

Hi Andy,

That Abel Cine test looks pretty convincing (the link in my first post in this thread). I've got an EX1R as well but I haven't had the time to do a black test yet.
