Welcome to the wonderful world of macro product photography.
First, you need to understand that when you photograph things at high magnification, you won't get a whole lot of depth of field. In this instance, very little is in focus. Look at the leftmost two pendant rings at the bottom of the earring on the right: just that little bit is sharp, and most of ...

It's looking like that the biggest difference is the updated 18-55 kit lens - from the early reviews and comments, it's a non-trivial upgrade over the older EF-S 18-55 f/3.5-5.6 IS II lens, in all of optical quality, usability with filters (due to the non-rotating front element) and the advantages the STM gives for video shooters. Given that a significant ...

According to this page, the IID2 has no flash capacity, while the IIS2 does.
Quoting:
The IID2, like the rest of the IID line has no flash capacity. Built
through 1956, production was slightly over 16,000 units.
Like the IIF, the IIF2 has flash provision for bulbs only, the slow
speed dial has no X on it. Unlike the IIF, this was a low ...

Wikipedia lists Canon's (outer) throat mount diameter as 54mm vs. Nikon's at 44mm. This means, at the mount, there is an extra 15.7mm of circumference on a Canon lens vs the same Nikon lens (assuming the lens is throat-diameter-limited). Depending on how Zeiss chooses to incorporate this extra girth in the packaging of the lens, the amount of additional ...

Be sure you are selecting the Single shooting option in the Drive mode setting rather than the One-Shot AF option in the AF mode setting. When the AF mode is set to One Shot, the camera can still fire continuously. With One Shot AF once focus is achieved the focus will lock until the shutter is released or the half-press is released.

Silent shooting mode does not affect Image Quality in any way. Rather, it affects the way your 5D mkIII cycles the mirror and shutter curtain for each shot you take.
The silent mode single option uses a slower speed to move the mirror up out of the light box. The first curtain opens, and then the second curtain closes as normal. But then, nothing else will ...

Power Focus is described on Canon's Infobank page as "a mode that allows you to drive the autofocus motor electronically instead of having to use the focus ring." As you indicate in your question, it's meant for changing focus from one point to another very smoothly, for use while shooting video.
As one doesn't normally change focus in the middle of taking ...

This is ultimatly a fairly subjective question. I think it does a pretty good job on my 5D Mark iii most of the time. It's also worth noting that you can have the 5DM3 save the individual files used (including in RAW format) so that you can always use software later even if you decide you don't like the JPEG that it produces. There are also multiple ...

If the index mark on your photo was at the center of the original image, the purplish blotch above and to the right of it is a ghosting of the bright light source the same distance to the lower left of it.
Ghosting is caused by the light from extremely bright sources (relative to the rest of the scene) reflecting off the front surface of a lens element or ...

Then a wide focal length is the ideal, which you already got - 18mm on a T2i (1.6x crop factor) is ~28mm on a full frame. Wider than that and you'll start getting some serious perspective distortion you'd need to correct.

Then a fast telephoto and good AF is essential. You already have a telephoto, depending ...

On a crop body camera, the 18 to 55mm is really your every day or "standard" zoom range. You might benefit from a slightly longer range, but most likely your biggest gain would be getting a "faster" lens.
When we talk about the speed of a lens we're talking about how wide the aperture (the hole that the light is focused through) can get. The faster a ...

I would pick up the Canon 50mm f/1.8. This has already been covered at length by multiple other threads here, so take a look at some of these great questions/answers:
Is it worth it to have the 50mm f/1.8 Canon lens?
Do I really need a fast 50mm lens?
Why do people recommend 50mm or other prime lenses as starting lenses for learning photography?
50mm tag - ...

To bluntly answer the question: "Why not enable it by default?" The obvious answer is "because it has drawbacks". Otherwise it would be enabled by default :).
Looking at this article from Canon directly explaining the option for the 1DMkIII and 1DSMkIII, then at this one for the 7D, I think we can safely say that the effect will vary depending on the camera ...

The differences are so minor many review sites are basically copy/pasting their T4i reviews, replacing the pictures, and editing the differences if they're posting reviews of the T5i at all. The new STM kit lens is probably the most significant change, especially for those shooting video as well as stills.
From The-Digital-Picture:
Here is a list of ...

The silent mode is wonderful for situations where you need to limit noise. It comes at the expense of a slower mirror movement and thus more shutter lag and slower continuous shooting.
I know the manual also talks about the difference between the Silent LV modes (yes, it is live view). Personally, those ones I didn't remember anything about because I ...

Possible causes of the problem.
The memory card used is does not meet the standard requirement of the DSLR, e.g. (the required SDCard should be class 6, but the installed is of lower class). This can be a critical factor that's why it is wise to check the requirement first before buying. Not all memory cards are the same.
The Memory card is damaged. ...

In my opinion, the EF 75-300mm f/4.0-5.6 lenses are some of the very few lenses in Canon's current lineup which should be avoided (the others are the unstabilized 18-55 lenses, because the price premium for the stabilized version is so small). As can be seen from this review, it's not a good lens; all that applies to both the USM and non-USM variants. You'll ...

There's never going to be a shot which can't be achieved on the 6D or the 5D Mark II due to the lesser AF capabilities of those cameras - with enough precognition (also known as experience), you could have manually focused on exactly where the action was going to occur and not needed any AF at all.
That's not to say that you won't get a higher proportion of ...

There simply is no such lens. 12mm is extremely wide on full-frame and, if you are talking about rectilinear lenses, only Sigma ever made any. Their 12-24mm lens is now in its second version but is essentially the same lens. Going with a fisheye, there are still only two models, one from Sigma and one from Canon. Neither accepts filters.
The extreme ...

It is difficult to pin down camera sales for the US only, as Canon and Nikon have many divisions (printers, imaging, instruments) and don't seem to report financial results at a very detailed level).
According to their own data (worldwide):
Canon (fiscal year ending 31-Dec 2012)
sold 8.2 million interchangeable lens cameras (Canon reference, page 3)

If you are doing weddings, the extra stop of an f/2.8 lens is almost essential when shooting in churches that don't allow the use of flash. For about the same price as the EF 24-70mm f/4, you can buy a Tamron 24-70mm f/2.8 Di VC. The reviews I have seen place it between the original EF 24-70mm f/2.8L and the EF 24-70mm f/2.8L II in terms of sharpness. The ...

I think (I'm not sure though) there is no built-in command line tools for such task. Instead, you can use third party softwares. Allow me to introduce you to very nice ImageMagick.
It is a set of cross-platform command-line tools that allow you to do a lot. It has lots of tools and also many scripts based on it are available online. They have also a forum ...

If you are interested in this, I would suggest getting 'dcraw' which is a command line RAW converter. There is a Mac version for download from the site, the source code, and if you have HomeBrew installed, you can install it via 'brew install dcraw'.
The 'dcraw' program allows you to specify a variety of options including the Gamma and Exposure level ...

I can only answer your second question - i.e. if anything can be done to resurrect these files. As others have mentioned, that uncorrupted version you're seeing briefly as you import them into Lightroom is the preview JPEG generated in-camera when you shoot RAW. There are plenty of tools that will recover those previews for you, hopefully even if the RAW ...

I think you have two questions:
what causes the file corruption:
bad flash memory, 80% of time.
When I view them in Lightroom or Windows Explorer, the files show normally for a split-second, then are over-painted with the light area you see below. Why?
Normal. A raw file usually embed a preview JPG and the program (OS, Lightroom etc) will first ...

This is often down to transfer from card to computer, not corruption on the actual card.
I have found that Windows Explorer tends to be the culprit - do not copy files from your card simply by dragging/dropping in Explorer - use a different tool.
I have used the free 'FastCopy' file copier with 100% success. It has a verification option that you can use to ...

DSLRCameraRemote, as linked above, is no longer supported by onOne Software nor is it available via the iTunes store.
Alternatives? There are none.
Recently I downloaded xRemote DSLR as it also uses a camera tethered to a computer AND then wireless connection to the iphone/ipad, like DSLRCameraRemote but it has no live view. For me, this is a critical ...

There are variations in Canon DSLR.
I had Canon-XT and used non-EMF chipped adapter with very accurate exposure in AV mode. I just turn to the desired aperture setting, get AF confirmed, and take the picture.
For 5D, the story is a little different for the camera's brain is different from the lower level DSLR. I used EMF chipped adapter, and need to adjust ...

Silent shooting has nothing to do with image quality. It is all about the quality of your personal impact on the event you are shooting. With quiet shooting, you can have a minimal impact on that wedding, allowing the Bride, Groom, and audience to watch that final kiss...without the loud, distruptive "CLAT CLAT CLATTER" of a slapping mirror. Same goes for ...

Spend $100 on the 50mm F1.8. Take photos with it. Its a nice lens, very inexpensive. If you still think your photos are not sharp, you will know that its you, not the lens. If you like the new photos, then think about spending more on a better lens.
I replaced my kit lens with the EFS 17-55 F2.8 and love it. It changed everything about my photos. But its ...
