Looking at the EXIF data in the posted photograph, i.e. extra information also stored in the image file, such as camera and lens model, and camera settings, I can see this setting: Exposure Bias Value: -5 I assume that "Exposure Bias" is what is also called "Exposure Compensation". I.e. you tell the camera, that this should be darker or brighter than ...

Normally I'd suggest upgrading lenses and not bodies but in this case going to the 6D is going to solve your two problems: The 6D has significantly better low light performance than the T2i/550D Your 50mm will have the same field of view on the 6D as a 30mm on the T2i I recommend you get the 6D and then maybe, if you miss the field of view of a 50mm on a ...

First, the thing you need to remember about noise is that it is only indirectly related to ISO. The real culprit where noise is concerned is a low Signal to Noise Ratio (SNR). This is technically answered using controlled testing to illustrate the point in this question: Is high ISO useful for photography? This answer to another question addresses the more ...

The maximum file size on FAT32 is 4GB-1. I'm not familiar with the original 7D (I have a 7D II), but unless the firmware is programmed to record to multiple files, switching to a new file automatically when you hit the 4GB-1 limit, that's going to be your limit. Perhaps recording in one of the lower resolutions will allow you to go longer time-wise, but the ...

Several things could be going on. Based on the question as originally written you might have been experiencing buffer congestion. When the buffer is full the camera must wait until enough space has been sufficiently cleared from the buffer as the data is written to the memory card before it can take the next frame. Under such conditions, the "double tap" ...

No. P, Tv, Av, M, Bulb and (in our discussion) the Custom modes (C1, C2, C3 etc.) have all different/independent values for Av and Tv stored in separate memory locations in camera's NVRAM for the user-definable (constant) part of the said program (none for P, Time for Tv, Aperture for Av, both for M etc.).

5472 × 3648 pixels at quality=81 One of the ways to check: exiftool -b -previewimage -w jpg canonraw.cr2 This will extract the preview from canonraw.cr2 file and write it next to the canonraw.cr2 file as canonraw.jpg. Next, run imagemagick/identify over the canonraw.jpg like this: identify -verbose canonraw.jpg | grep 'Quality\|Geometry' exiftool: http:/...

Yes, there's a way to disable flash by default when using Auto mode: just use the P mode instead. The P mode calculates the ISO, aperture and shutter speed automatically as well, but leaves some options for you to tweak. You can for example disable/enable the flash yourself and also decide to set the ISO yourself.

Clearly, something is broken. This camera has interchangeable lenses, so the first thing you need to determine is whether the body is damaged or just the lens. Switching for a different lens and testing out the camera is the first thing there. And if you can try the lens on a different body (borrowed from a friend?) you can also confirm that separately. ...

I have the Canon 7D Mk II and I have seen it last upwards of a month if not longer on standby without the GPS on. I don't know what the official length of time is from Canon, but I find it barely uses any battery when in stand by from my experience. Even the one weekend I left the GPS on, as long as the GPS is locked in, its not to hard on the battery. If ...

If you've got Live View set to "exposure simulation" but the camera is unable to communicate with the lens you'll have issues. That is because "exposure simulation" needs to know 1) at what aperture the lens is currently set (when shooting stills in LV the lens remains wide open until the shutter button is pressed all of the way), 2) at what aperture the ...

Possibly, but the information to decode date of manufacture doesn't seem to be known outside of the Canon company. Canon bodies and lenses used to have a date code stamped on them, separate from the serial number. That practice was phased out for some, but not all, products in 2010 or 2011. According to Wikipedia, the Canon 7D was announced in late 2009, ...

3200 does seem to be the safe answer, but that said -- don't set your ISO at 3200 and then underexpose. You are far better off to shoot at a higher ISO and get a good exposure, than you are to shoot at 3200 ISO, underexpose and then try and bring it back in post. A well exposed noisy exposure is better than not noisy dark frame. A well composed, well ...

Have you checked which metering mode you are using? If you are for example are using average metering then the camera will use the whole frame to decide what setting to use. For example if the overall frame is too dark the camera will try compensate for that. Normally the different metering mode are: Average metering - Uses the whole frame Center ...

From an image quality standpoint the 6D has a fairly significant advantage over any of Canon's current APS-C offerings. Since the 7D Mark II has been announced but not yet released and hasn't been in the hands of most reputable reviewers/independent testers yet, it is hard to judge the image quality. Suffice it to say it would need a totally revolutionary ...

The EOS 6D and the EOS 7d Mark II are very different cameras in so many ways making them hard to compare. The EOS 6D is the least expensive full frame DSLR from Canon and the 7D Mark II is their most expensive APS-C. You say you are into landscape and astrophotography and in my world buying a 7D Mark II over a 6D for that is crazy. The 7D Mark Ii is made ...

The support for the Canon 7D's RAW files was incorporated in Camera Raw 5.6 and the latest version of Camera Raw supported by Photoshop CS2 is 3.7 so there are no support for the .cr2 files created by the 7D in CS2. Unfortunately there is no way of opening these files in such an old version of Photoshop (unless there's a strange hack that I don't know of) ...

Let me start by saying there isn't a wrong answer. Either camera you suggested is a HUGE improvement over an entry level model and you are jumping pretty much clean over the mid-range models. I personally jumped from an xTi (400D) to a 5D Mark iii, but I made that large of a jump because I was starting commercial photography work on the side. I know you ...

Hoping I haven't misunderstood your question, it is as simple as this: Turn Dial on top left of Camera to “M” Press the “Q” button on the back of the camera Set ISO to auto Alternatively Turn Dial on top left of Camera to "M" Press the ISO Button on top of Camera and turn the top dial to the left until you reach "A" now you are free to set the aperture ...

... can I use the old lenses with this new model? Yes. The 7DMkII is a "crop" body, so it can use both EF and EF-S lenses. It's only if you move to a full-frame body like the 5D/6D bodies that you can no longer use EF-S lenses. And if so, how much quality would I be losing by doing so? Since both of those are considered to be entry-level kit lenses, ...

Check advanced options to see if ISO step is in 1... if it is, change it to 1/2 or 1/3 as needed.

The EOS Lens registration data is intended to be used by either: The camera when processing the raw data from the sensor to produce a jpeg image (or to produce a jpeg preview image when the file is being saved as raw data). At a minimum the camera uses the information to do Peripheral Illumination Correction. Some but not all Canon EOS cameras can also ...

Because sometimes it is the most appropriate tool for the job. For a lot of shooters, it meets a need and they buy it. The following cameras are among those I have at my disposal: EOS 5D Mark III EOS 5D Mark II EOS 7D Mark II I use all of them regularly. Which one I use for a specific task depends on which one gives me the best chance of getting the ...

As this occurred only to the RAW files and not the JPEG copies of the same photo, that means by far the most likely explanation of the error is that your SD card is giving up. Throw it away, get a new one - it's just not worth the risk in using it again for what is a (relatively) disposable bit of kit. In terms of recovery, you're almost certainly not going ...

You say the 550D is happily serving all your needs and that you're only looking to upgrade because "it is time". May I suggest keep your 550D. It's a great camera by all means and you're already enjoying it. You can put the money you were going to spend on the camera (both that you mention would set you back more than a thousand pounds) and instead invest ...

There are many reasons any given camera's images can become less sharp over time. I doubt you're going to get a solid confirmation, as it would be incredibly difficult to isolate this from other sources of sharpness reduction/variation, outside of perhaps a DxOMark laboratory (with controlled conditions, several brand new cameras, known-good lenses, etc). ...

7D owners, I hope this fixes your problem, don't waste your time resetting the camera, wiping battery contacts, putting it in the freezer, etc. I didn't mention in posts on other forums, I've been an instrument technician for more than 40 years and don't have a problem going into the camera and making the repairs, I've done so on other Canon cameras and ...

LiveView is generally better when using manual-focus lenses (or focusing most lenses manually, as mentioned by others). The reason is that the focusing screen seen through the optical viewfinder in the 7D is tuned for auto-focus shooting, which makes nailing focus manually more difficult. From KatzEye Optics: The standard Canon 7D screen is optimized for ...

They'll fit and work on the 7D Mark II but... It is almost a waste of money to spend it on the 7D Mark II if these two lenses are all you'll ever use on it. You would see a much better improvement in your images, especially of sports, by spending the same money on a good lens or two and using them with your current body. For about the current going rate ...
