RichRMA: What good are these things with such short transmission ranges?

500 meters? In practice, it's more like 4,000 meters but regardless do you know what this tiny thing would look like at 500m? A dot, if you're lucky.

In practice you're going to keep a little thing like this within about 200m.

Lee Jay: Let me talk for a moment about the lack of a touch screen.

I plan to shoot video, mostly handheld of high-speed subjects. In other words, I want to use it like a camcorder. That means I want an eye-level viewfinder, and that means, I'll be using a Hoodman or similar attached to the LCD.

I'm not sure the Hoodman would inadvertently trigger a touch screen, but it would most certainly render it useless. Given the way I intend to use it, it may well be better off with a fixed non-touch-screen LCD and a joystick.

Not a filmmaker, and phase detect AF during video is pretty greatly more important to me than anything Sony or Panasonic have to offer.

Weird...my top two aren't even listed, and they're from Canon.

That sounds reasonable until you realize the 70D doesn't have a joystick. If it's either a T/S LCD or a joystick, that's a tradeoff, not a slam dunk. If it's just a fixed touch screen and joystick, then turning off all touch input would have to be an option in the settings so that it didn't get messed up with the constant touch of an LCD loupe.

DVT80111: About time Canon but I won't cancel my Tamron 150-600 order.

400mm is no quite long enough for birds.

Based on the MTF charts, the Canon looks to be sharper with a 1.4x than the Tamron is bare at 600mm.

Couple minor errors, but a good video and obviously a good bit of effort and time.

On 'See Impossible': Canon counts down to... something. article (1669 comments in total)

I'm hoping for a compact APS film camera with a 38-65 equivalent f/7.1-13.5 lens and no flash.

On Post-Photokina polls - Tell us what you think article (198 comments in total)
In reply to:

ThatCamFan: 8.5% Don't know anything about photography apparently according to the poll.

Those people may be the ones that realize the poll itself is stupid because it doesn't specify what you are shooting. Some of the best and most difficult photography I've ever seen is done with sensors of around 1/4" - planetary astrophotography, with real focal lengths around 10m (10,000mm).

Other things are better done with larger sensors, but MF isn't too great for sports and wildlife because the cameras and lenses are just not built for that purpose.

Lee Jay: I'm having a hard time understanding how this could not produce lots of astigmatism, coma, CA and so on. Also, it would seem that aperture would be constant leading to either a very narrow zoom range, some crazy fast f-stops at the wide end, or some crazy slow f-stops at the long end.

Many aberrations are not correctable in software, and corrections of many sorts cause an increase in noise or a decrease in acuity. It's not a magic bullet for everything. Mostly it's good for a small amount of vignetting, moderate geometric distortion, and lateral (not axial) CA.

It probably would, as it would almost certainly mean horrible aberrations.

On GoPro announces Hero4 lineup article (111 comments in total)

The Debut Hero is twice the cost of a Möbius, doesn't have interchangeable lenses, and is about as aerodynamic as a brick. Hmmmm...which to choose for a fast R/C airplane...I think I'll get two Möbius cameras, a medium focal length for the plane and a long focal length for my hat so I can make my own flight videos from two angles.

#4 isn't a particularly good shot of Horsehead and Flame. I routinely see better ones on Cloudy Nights and in other places. It's not bad, but it's not special either.

Here's one I just found that I like:

lcf80: Almost every single camera provides RAW images using 12 or 14 bits per color, free tools like GIMP and RawTherapee support it. And Photoshop Elements still useless, in 2014? Open your eyes, Adobe.

There would be no difference, as the camera raw plugin will operate in 16 bit ProPhoto for the raw conversion for both applications.

plasnu: He claims that Canon sensors to be the best, but I really want to know what measurements he is looking at.

My point was, who could they have gone to to buy a dual-pixel sensor?

Okay, who makes a better dual-pixel sensor than Canon?

I'm a semi-pro with a lot of gear, over a quarter of a million photos under management, and I prefer Elements over CS6, and that's what I use. I do most all of the work in Lightroom meaning the work I do in Elements isn't limited at all by the fact that it's 8 bit.

I get consumers all the time asking me for stuff that would make the item not work. Should I provide them anyway?

I use Elements. I have CS6 but Elements is faster and easier to use.
