Silent shooting mode normally (*please see the end of the answer for a notable exception) does not affect Image Quality in any way. Rather, it affects the way your 5D mk III cycles the mirror and shutter curtain for each shot you take. When shooting via the viewfinder: The Silent mode single option uses a slower speed to move the mirror up out of the light ...

The base ISO of all Canon cameras is ISO 100. This is the ISO with the lowest gain, without any in-camera magickry to achieve the setting (like ISO 50, which mucks with the actual exposure settings behind the scenes). There is a lot of conjecture and misunderstanding about Canon's ISO settings because they use a "real/push/pull" model for ISO settings, ...

If money's no object then the 5D mkIII is the better camera in almost all areas (viewfinder, resolution, autofocus, shooting speed, card slots, sync speed, weather sealing, video). Canon make a GP-E2 GPS logger and WFT-E7 wifi grip for the 5D mkIII if you need this functionality. Reasons to go with the 6D would be mostly due to weight (of both the camera ...

I have used the exact setup you are using. I found that the 2X Teleconverter iii worked wonderfully with the 70-200 f/2.8 IS II on the 5D Mark iii. I actually tested it in far harder conditions (shooting a wedding in a relatively dimly lit gymnasium) and it worked quite well. Particularly since you will be using the shorter focus distance setting, I ...

It is not possible to transfer images out of the memory card faster than its maximum read speed. All you need then is a sufficiently fast card reader. With USB 3.0, there is enough bandwidth to exceed the transfer speed of the fastest current Compact Flash and SDXC cards. Lexar claims 500 MB/s top speed which is faster than Gigabit Ethernet (1000 Mb/s = 128 ...

There are several menu settings that affect when the red illumination of focus points is activated. By default, the red indicator lights will only illuminate over the active focus points when focus is achieved and the brightness of the scene in the viewfinder is low. You can modify this in the menu settings. Under the AF 5 (purple) tab, select VF display ...

Neither solution is acceptable in my opinion, especially for something as important as a wedding. Large hard drives are cheap and spare compact flash cards are not terribly expensive, so I would just get more storage and shoot raw. If computer processing power is your limiting factor - that can be a little more expensive. Even so, a decent PC ...

According to the guys at Magic Lantern, when you open the SD card door and the light flashes while it accesses the SD card, you should wait until several seconds after the light stops flashing as it is still accessing the card (which is silly, because that light has one job!) or you can cause the camera to lock up and drain the battery.

Do you have any other basis for comparison, does this power consumption rate sound expected and acceptable? I see similar results on the 6D: GPS uses a lot of battery power. It also uses battery even when the camera is otherwise idle. Turning off both GPS and WiFi will give you significantly improved battery life. That doesn't mean that GPS isn't still a ...

This is an easy answer. Are you shooting in lower light or need the most out of focus background possible? Then you will want the Canon 70-200mm f/2.8 L IS MkII. Are you often carrying the lens on your back and often needing the extra 100mm reach? Then you will want the Canon 70-300mm f/4-5.6 L IS. Do you need to both shoot in lower light and have the ...

It doesn't look too bad to me. You have to consider that when you're looking at a 5D mkIII image at 100%, that amounts to a considerable enlargement. It's rare to get something really pin sharp at that magnification. The focus point is quite forward so the trees in the centre of the frame are at or near the far limit of the DOF. That combined with the ...

MicroSD cards are supported provided you use them with an adapter. The 5D Mk III manual says it can use cards over 128GB capacity so I would assume there is no upper limit.

I don't know what it costs to replace a 5D Mark III shutter in the UK. If the work is done by a Canon Service Center in the U.S. it runs around $320 before any discounts, such as CPS (Canon Professional Services) membership, are applied. Any applicable shipping charges would be additional (with most CPS membership levels return shipping is free - with the ...

The Canon EOS 5D Mark III has a resolution of 5760 x 3840 pixels, or 22.1 MP. It has a 3:2 (1.5:1) aspect ratio. A2 sized paper is 16.5 x 23.4 inches (420 x 594 mm). It has a 1.414:1 aspect ratio. This means we must either: Leave blank spaces at the top and bottom of the paper to use the full image width on the width of the A2 paper. This would leave us ...

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 ...

The 5D mk2 was released in 2008, the mk3 in 2012, 4 years is a long time in technology. The mk3 is much better, it is better because of 4 years of sensor technology research, the pixel size makes a difference only if everything else is the same - and when you compare a models that have a 4 years difference everything isn't even close to the same. If you ...

Is there a simple way of quickly swapping a circular polariser between lenses (of different filter diameters)? Not really. The simple solution is to have a polarizer for each lens so you don't have to swap them in difficult conditions. The cost-effective solution is to do as you are currently doing and use step down rings. Magnetic filter holders and ...

I have a 6D and a 5D Mark IV. I haven't used the 5D enough to profile its battery life, but in my experience with the 6D, GPS causes maybe 15% battery drain per day. And with the 5D Mark IV, it should use much less, assuming you take advantage of the new "mode 2" behavior that turns GPS completely off when you switch off the camera. So in a three-hour ...

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 ...

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 ...

I have had identical issues with the 580 ex II. Change the flash setting in the cameras menu to 'average' not evaluative it fixes it. I don't use evaluative for the camera settings without the flash either the same issue happens and photos under exposed. I think Canon need to revisit their 'evaluative' system. Hope this helps....

I don't think there is a way to do it automatically outside of writing your own plugin and I'm actually not even 100% sure that that would do it. For partially manual options though, use the rating filter on the previous import collection, set it to less than or equal to no stars and you will only have the unrated photos listed. Then select them all and ...

I am a 5D Mark III user, and make frequent use of the spot-AF mode as you describe. To switch between AF modes on the 5D Mark III the first thing is: DO NOT BE IN AUTO MODE (The green one on the dial). This will automatically select all 61 points as potential AF points and you can't change it. Use P/Av/Tv or M mode. In your settings there you can choose ...

The blur can be measured by converting to XYZ colorspace and zooming into a tree trunk with a bright sky as the background. You then measure the brightness profile accross the rapid change in brightness (make sure you pick an area with small gradient in the direction parallel to the tree trunk). I then used this method to estimate the blur. Since the image ...

The Official Canon 5D Mark III website says: Recording Media CF Cards (Type I); Compatible with UDMA CF cards; SD, SDHC, and SDXC Memory Cards Note: No microSD is supported unless you use a microSD-to-SD adapter. It's also worthwhile to mention, a MicroSD-to-SD adapter would not bring any loss of performance (either in writing or reading speeds) since the ...

I have used the Xume adapters. Awhile back I standardized on 77mm filters, and also found myself swapping them around all the time. I thought the Xume would be a perfect solution. When I bought them, they did not have a dedicated Xume-compatible lens cap, so I "made my own" with old-school screw-on/off caps and dedicated Xume rings for them. I also put Xume ...

AI (Auto-Intelligent) Focus (It is an uppercase "i", not a lowercase "L" or a numeral "1") is one of those things that sounds good in theory but often doesn't work well in practice. Sometimes it does, but at other times it doesn't. I prefer to set my camera to either One Shot or AI Servo, rather than splitting the difference with AI Focus that starts in One ...

The focus-point issue depends on your personal habits. Many people who shoot a variety of non-action photography, only ever use one focus point. Yes, one focus point, not one cross-type, one focus point in total. You do that using the focus-lock and recompose technique. On the other hand, having multiple focus points and particularly more sensitive ones is ...
