Last fall, Hasselblad asked me to evaluate advance copies of the CFV 100C and 907X. This review is based upon that evaluation. At Hasselblad’s request, I have delayed publication of this post until the public announcement of the camera, which occurred today. The CFV 100C is a back for a V-series Hasselblad based on the… [Read More]

Visible noise and CFA filter spectra, part five
Continuing my exploration of the effects on color accuracy and image noise in various cameras, I ran my simulation on a group of cameras with lighting from D22 through D90. Here’s what I got for color accuracy, using sensitivity metamerism index (SMI) as the metric: With the exception of the Sigma DP1 Merrill, which is… [Read More]
RRS L bracket for GFX 100 II — quick review
I just got mine. Typical high RRS quality. Allen wrench mounts in the base using two clips. If you’re not careful when you pull the Allen wrench out the clips will come with it. Just slide them back in. But do that before you mount the plate to the camera, because you can’t put them… [Read More]
Visible noise and CFA filter spectra, part four
A long-time reader commented on the previous post: One aspect of low light performance is low noise under warm lighting. At sub-2700K, many older cameras end up with tremendously large WB multipliers for the blue channel, when compared to “modern” CFAs. I decided to take a look at that. I’ll show you what I found,… [Read More]
Visible noise and CFA filter spectra, part three
I’ll now show you some charts that summarize the material presented in the last two posts, and after that I’ll give you my takeaways. Here’s the SMI for all of the cameras simulated: There are two clear winners here, the XYZ response, and the optimized set of Gaussians. There are five losers: The Leica M8,… [Read More]
