In reply to:

Victor Engel: "Image corrected for lateral CA, distortion and vignetting in Lightroom, at default sharpening." Why? For a lens review, shouldn't these items be uncorrected?

If you will re-read my original post, you will see that what I am objecting to is the use of Lightroom correction filters. Certainly it doesn't take a bunch of expensive equipment to not use those filters!

What is your beef? I'm not allowed to express my opinion?

Because that would have little to do with this review, which was what my comment was about.

What Canon is described as doing seems to be what we've been advocating in the forums for years.

Roland Karlsson: Just so you understand. As it is a 30 mm F2.0 lens, then at 4x it will have a max light gathering of an F8.0 lens. If you stop down to F8 (for good measure) it will have the light gathering of an F64 lens.

You will need lots of light!

What do you mean by "evenness of glass refractive index"? I think a lens would perform very poorly if the refractive index wasn't consistent across the glass. You must have meant something else.

Compare to Canon's MPE 65 with an aperture range of f/2.8 to f/16 and magnification range 1x - 5x.

Anyone who has done any sort of photography using magnifications in this range is familiar with the light falloff. No big deal. You're probably going to use flash anyway. Now calculate guide numbers at 30 cm. :)

Then don't call it a lens test. That is all.

Sure it is. Lenses are by nature analog. That is exactly my point. If it is the lens being tested, test the lens, not the lens/camera system. If it is the system being tested, don't call it a lens test.

Fuji what? There are lots of Fuji lenses. I've never heard of a lens that can't be used on film. Seems absurd.

I've never heard of software correction being required for a lens. How would those lenses perform on film? There's no software there.

Can you name an example of a lens that requires software correction?

alvareo: Why are smartphone comparisons here so incomplete? I can't even compare JPEG vs RAW of the same scene

Sure you can. That's what I'm looking at right now.

Robert Schroeder: I never cared for ANY iPhone, and for good reasons, too, and I don't even need to look at any of those "10 reasons" (and actually I didn't and I won't) to know that the iPhone 7 won't change a thing in that regard.

I didn't either, until I became an iOS developer. At that time, my device of choice was an iPad, which I had previously ridiculed. When potential employers were repeatedly surprised that I didn't own an iPhone, I decided to make the plunge. I have a 5S Plus now, and will be upgrading when my provider offers it. I haven't seen yet how it performs in low light. I hope it does better than the 6S Plus. I think some of the other phones perform much better in those circumstances.

Any Little League batter knows not to hold the bat that way. Surely a professional should know better:

Always keep the seal on the top, i.e., swing with the grain aligned with the direction of the swing -- unless you WANT the bat to break.

I've been saying for years that DSLRs should do this.

WGVanDyck: This is essentially a photo and image site and I find dark grey to black backgrounds work best for that type of content. One of the reasons I like DPR over that other site.

For me, it's just personal preference. White surrounding a photo looks clean, but the photo appears more washed out. Maybe it has something to do with aging eyes.

florianpainke2: This is the peeps that grew up reading books vs. those who spent their time in front of a computer running DOS ... ;)
But seriously, thanks for giving us a choice. This way everybody will be happy. (Okay, not everybody, some people will always find something to complain about ...)

Personally I like the new light theme very much. Much easier on the eyes. Can't wait to have it on the forums! :)

The Kindle app for iPad has several settings for page color and text color. I prefer using a setting that's about 2/3 white, with dark, but not black text.

Dark background is good for photo-rich pages. Light background with dark text is better for the forums, in my opinion. I don't see the new white skin in the forums, however. I guess the preview does not extend there.

ZAnton: Tried it. Eyes hurt. Back to black.

Funny. The main reason I've been asking for white is that bright text on black hurts the eyes. With a white background, the eyes stop down to a comfortable level and I don't get burn-in. With black background, my eyes compensate for the black by opening up, with the result that the lines of text burn in to my retinas, leaving an afterimage.
