I am looking for a 35 mm lens for astrophotography. I've been looking at RF 35/1.8, but the sticking point is coma/astigmatism which is severe wide-open. But ... does this problem go away when the lens is stopped down? For example, here is an aperture sweep of my RF 24/1.8 which has bad...

I'm in the market for a wideangle prime, and I'm really torn between Canon RF 24/1.8 and Sigma 28/1.4 Intended uses: astrophotography (tracked), after-dark walk-around shooting in cities and towns (travel), and daylight landscape photography. Wideangle lenses owned already: RF 24-240, RF 16/2.8...

I've got a RF 24-240 that has trouble in freezing temperatures. When the temp is below 0C/32F, the image stabilizer squeals and doesn't engage. In fact I think it is being counterproductive to stabilization. The problem gets worse the colder it gets. I had it out at -20C/-5F and the squeal...

I'm happily running Windows 7 on my PC workstation. Microsoft really wants me to upgrade to Windows 10. I have Windows 10 running on a little laptop, so I'm familiar with it, and I must say I have no preference of one over the other. Should I upgrade before the July 29 deadline?

Todays sensors have heaps of megapixels. More than you can shake a stick at. More than most of us need. Now, today's sensors still have a bayer filter with a basic R,G,B pattern. RGB is what our monitors use. Newer sensors have standard green alternating with an expanded green, but it's...

Anyone have an idea when Adobe is going to launch CS6? I was about to spring for a CS5.5 suite but my store was out, and said they probably wouldn't get any more copies until the release of the next version. The sales rep was guessing later this month, then shipping a month after that.
