When we talk X-Trans virtues, we often talk about the more film like looking grain, the less color noise at high ISO, less moiré, sharpness boost etc.

But the X-Trans array might have some other advantages most of us would not think of. For example, in today’s case we see how ideal X-Trans is to create a DIY Spectorscope to measure the wavelengths of light.

In fact, when comparing the X-Trans vs Bayer sensor for this project, mpr decided to go for X-Trans, because each column of the X-Trans sensor contains all three colors (red, blue, green), whereas each column of the Bayer sensor only has 2 colors.

This makes it a lot easier to use the X-Trans data for the spectorscope.

From there, mpr will guide you through the process and if you are interested definitely watch his video.

Nice to see yet another creative and useful application of the X-Trans sensor.

Sigma CEO gave an interview to DPReview. Here are just some excerpts:

• it seems that camera market shrinking has hit the bottom
• still people are switching from DSLR to mirrorless
• after the switch is completed, the market might shrink even more
• he is worried about the increasing price of cameras and lenses
• he is afraid that many might be able to afford these prices, especially young generation that want to switch from smartphone to camera
• cameras today have impressive specs that many might not need
• focus user friendly interface would be more important for customer, or smaller and lighter gear
• Sigma leads the lens industry by pioneering new glass elements, often being the first to test and prove their viability.
• other companies see Sigma using new type of glass and then start using it too
• Sigma’s plan is to have a relatively complete range of lenses for APS-C sized sensors
• but it seems there are no  I-series-style versions of the DC lenses, guesses DRP based on the CEO statements
• no aperture ring APS-C lenses seem to be planned
