<p>I mostly use a big lens and photograph objects at great distance outdoors, using a Canon 7D II. Sometimes the object I am photographing is too small to see in the viewfinder (even at 600mm), but when I bring the photo into the PC I can resolve the image.<br>

I was wondering if the Canon mirrorless cameras have a viewfinder that can digitally magnify the image, thus allowing me to discern detail in the subject?</p>

Just to elaborate. Of course I did reset the date/time when I first installed V2.03. I had to reset the date/time after I removed the button battery and put it back in.

Because the problem seemingly went away after I did this, I suspect it is related to the firmware (2.03).

Also, I took about 2,000 photos after installing 2.03 before this problem occurred. I never installed V2.0, expecting another update to fix problems introduced by V2.0..

I'm puzzled about the comment regarding the battery holder (BG-E7). I'm not aware of any systemic problems with this add-on. I use one on the 7D and on the 5D II. What problems have occurred with this device? It was one of the first items I tested. I removed it and put in a single battery and the problem did not go away.

I usually wait before upgrading a firmware in order to allow for bug fixes. So I just put in Firmware 2.03 for

my 7D body a week or so ago. I never put in version 2.0.

Yesterday, after returning home from using the camera, I wanted to review some photos and discovered that the

camera would not turn on. The battery is full. In fact I use the battery holder with 2 batteries in it. So I

reseated the batteries and noticed a flashing red light on the rear when I did so. I turned the camera on and it

started with the usual sensor cleaning.

Then a few minutes later after turning it off, I tried it again and again, it would not turn on. Reseating the

batteries again fixed the problem.

However, a few hours later I tested it again and not only would it not turn on, reseating the batteries did not

fix the problem.

I removed the battery holder and inserted a battery directly into the camera body. This did not fix the problem

either.

Now I wonder if this is a problem with the new firmware or some other problem - like a dead off/on switch. Of

course I cannot upgrade the firmware (if such were available) if I cannot turn on the camera.

The body has about 110k shutter releases on it.

Sometimes describing an issue helps. I just tried reseating the date/time battery and the camera turned on (with

the battery holder BG7 removed). I had to re-enter the date and time, though. I re-attached the BG7 and it

still turns on OK.

Now I wonder if the problem was with the seating of the Date/time battery, or with the firmware. That is,

perhaps resetting the date/time also did something to the firmware.

Any comments? Similar problems?

Normally I shoot something and later dump the cards directly onto my desktop

and view the images on a Viewsonic 22-inch graphics CRT monitor.

Recently I was traveling and used my laptop with an external drive that I

later attached directly to my desktop.

I use a Canon EOS-1 Mark II and have the latest version of Canon DPP on both

the laptop and the desktop. I shoot only RAW images (as I have noticed colour

balance inconsistencies between simultaneous JPEG and RAW images).

On this occasion my photos appeared perfectly exposed on the LCD of the laptop.

Later, when viewing the same photos on the desktop CRT using the same

software, they appeared underexposed by at least 1/2 stop.

When I print a photo from my desktop, I get what I see on the CRT monitor.

Most people now use LCD monitors.

I now wonder if I brighten the RAW images so that they appear perfectly

exposed on the desktop CRT, will they appear overexposed to someone viewing

them on an LCD? I know that the CRT has a greater colour gamut than the LCD.

Which is showing me the correct image? The LCD or the CRT.

Has anyone else encountered this issue?

I have noticed that when I look at images using Canon's Digital

Photo Professional software and when I shoot using RAW and JPEG,

that the JPEG colour balance is significantly redder than that of

the RAW for the same photo. The RAW looks correct and the JPEG

biased. I have not used any processing adjustments. All at

default. sRGB. Firmware 1.02 on EOS-1D Mark II.

Anyone else see this? Any fixes?
