Thanks, good to see, but really almost nobody uses 3200/6400asa with these backs!
(I'm on 70,000 exposures with my IQ3-100, and have never gone above 800, and that was one single emergency!)
I'd much rather see you post the 100/200/400 comparisons, without us needing to fill in a form!
I know, it's a business you are running, so maybe I should chillax!
That is true. With the IQ3 100 I cut off at 1600. Not that I was trying to use ISO 1600, but I felt like at ISO 1600 in situations where I had no choice, I was still getting the crispness and detail I wanted to see (with luminance noise reduction turned to zero). At 3200, I just wasn't. But - everyone is different, and I know some photographers pushed the IQ3 100 further.
What seems apparent to me is that the IQ4 150 may push my tolerance up to ISO 3200, as the detail I see is still in the realm of what I expect from medium format (I don't mind the noise so much, depending on the subject matter, I am more concerned with the bite and the detail).
Ideally, I and most would shoot at base or base + 1 or 2 stops. But everyone is different, different subject matter can work well at different ISO rates and noise levels. And sometimes we encounter opportunistic necessities.
There are ISO runs from 50 (or 35 on the Trichromatic), up to 12,800. So the entire range, including 400/800, is included. And with that said, this is all about data points, and the noise we see at IS 200 is relevant to some, the noise at 6400 is relevant to to others. And especially from a comparative standpoint to previous models.
On the subject of filling out the form, well, yes, we feel it is fair, but won't judge anyone who thinks it is not. However, on that subject, it has come to our attention today that the form is not forwarding download links to the email addresses. We have looked into this, and resolving it is not as simple as one might think. So for anyone who would like to see the raw files, please contact me directly via the email link below, or contact our
