Lenses / Re: 17-40L vs 24-105L
« on: December 08, 2012, 04:51:47 AM »
I have 'em both and I can unequivocally say: go for the 24-105. 24mm is more than half decent for landscapes and the lens is great for everything else. I was happy with it as my walkaround lens on a crop body and over the moon when I mounted it on the 5D3. IMO, the 17-40 is versatile on crop bodies only. It still is a very nice lens, but with 40mm or less I wouldn't want to do portraits or sports or really, anything but landscapes.

And then, IS.

YMMV but for me it'd be a no-brainer :)

Unless distant.star is Dutch. He still may be in "Sinterklaas" mood. In this Dutch holiday they celebrate by giving eachother (especially children) surprise presents accompanied with a verse that is giving clues for guessing what your surprise will be.  ;D
I'm Dutch, and at no point did the topicstart remind me of a Sinterklaasversje  ;D

You can just state that there's a typo in http://www.canonrumors.com/2012/12/gura-gear-giveaway/. No need for the guessing game - unless, of course, you don't want it fixed.

I need one. I'll buy one in the end eventually, since I do that with all bags, because so far I haven't found one that is any good  :( So, might as well ship it to me already! :)

Lenses / Re: Is this the normal bokeh for an L series lens
« on: December 01, 2012, 04:48:12 AM »
Probably becouse the surface reflect an "oval" beam of light!
I don't think so. Some googling led me to this (very interesting) page, which says:
Quote
Sometimes what would be a circular out of focus highlight in the center of the image has a lemon shape outside of center, gradually more near borders and edges. This is caused by mechanical vignetting because the optical path in the lens is too narrow. Resulting shape is often a intersection of two non-concentric circles, often described as "lemon shape" or "cat eye".
But that immediately raises the question why even a classy lens like the 135L (which was used for this shot, according to the exif data) shows such 'defects'. I'm assuming this is a consequence of shooting wide open (tho I'm not sure), is it something to do with the ratio between distance and aperture? Anyone?

Great shot, dirtcastle. What I don't get is how the 'lemony' bokeh shape in the bottom come into being. Could anyone explain?

Glad we could help :)

...although advising Eneloops is a no-brainer. You now know why, too ;)

EOS Bodies / Re: When will we have a full frame body below $1,000?
« on: November 24, 2012, 09:48:09 PM »
I don't believe that the FF sensors cost dramatically more to make than 1.6 crop sensors.
I do believe that. Exponential error rates truly are a bitch. But although an aps-c sensor can be manufactured for a couple of dozens of dollars tops, an FF sensor doesn't need to cost more than a few hundred dollars. You'd think that a $700 Rebel with a FF sensor slapped on would fit the bill.

However, stuff like the shutter, the mirror mechanism and the pentaprism needs to be a lot bigger too, and that isn't exactly cheap either. Now you can save money on most of those (say: pentamirror instead of prism) but that would chip away at the quality of both camera and images. And quality is exactly the reason to choose FF over crop. It would make no sense to produce an extremely cheap FF camera, unless of course the market for gear whores becomes substantially bigger than that for actual photographers. I may be naive, but I don't think that's the case yet.

By the way: every few decades prices double because of inflation, so a sub-$1000-camera will be less likely every year. If it is to happen, it'll need to happen in the very near future - say less than five years. Unless Sony starts making 450mm sensor wafers with excellent yields real soon, and I don't see that happening. And I don't see Canon invest in that sort of tech anytime soon at all.

All in all, my guess is never, but you may get lucky between 2015 and 2020 :)

EOS Bodies / Re: What will be the issue with the 6D
« on: November 24, 2012, 11:29:22 AM »
Errr, hmmm, 6D is a camera with GPS not GPS with a camera...
I'm sorry, I was trying to use humor to give an impression of how long a typical Canon battery might last while using GPS. I should've known not everyone pays attention to smileys. Next time I will use [IRONY]-tags.

« on: November 24, 2012, 08:19:19 AM »
I hope there is a firmware feature that lets the user adjust the gps tracking tradeoff power/precision
Gps is not a real battery hog if they just use a modern low-power chipset. My WinTec 202 (a recent microBlox gps logger) will log with walking precision for 24 hours on a single battery charge of 4,4Wh - about a third of the capacity of an LP-E6. So if you only shoot an occasional photo, a gripped, logging 6D might still last close to a week :))

Can't find if others have posted this already, but the release of the 24TS has apparently been pushed back to March 2013  :(

Landscape / Re: Solar Eclipse Next Week - Any Suggestions?
« on: November 17, 2012, 08:46:24 AM »
The Bing search engine had this stunning pic as their wallpaper a few weeks ago. I'd appreciate any insight as to how it was done.
That looks a suspicious lot like the sun's magnetic field. Although there might be tricks to take photographs of solar wind, I think they would require specialist equipment and more than just a few filters. I suspect this might just be an artist's impression, though.

EOS Bodies / Re: Canon's APS-C sensor versus the competition
« on: November 16, 2012, 05:03:07 PM »
You also get a little more reach for your sensor :P.
And a little less use for your expensive L glass ;)

« on: November 15, 2012, 04:48:05 PM »
Are you sure you've set it to just charge? If you selected 'test' or especially 'refresh' it will take much, much longer. Then, occasionally, my LaCrosse BC-700 will fail to detect a full battery. To check, I just remove and replace a cell which then will be marked as 'full'.

EOS Bodies / Re: Canon EOS 5D Mark III Blinking Red AF Point Information
« on: November 15, 2012, 01:00:12 PM »
WTF, then just give us a short AF blink when the AF-On button is pushed. Just like it was with the MarkII. At least it would be on the same level then. No reason to make this more complicated as it is.
At any rate, that would only work for the first shot - you still wouldn't know where the AF points would move for the 2nd, 3rd, ... shot. Which is the actual issue, because the red-flare-on-focus *is* available in One Shot mode (and we all set the DOF button to toggle between One Shot and AI Servo. Right? Right?). So don't oversimplify either ;)
