Dear all! I experience a slow startup time (boot time, wakeup from sleep) when using a CF card in my 5D3, firmware 1.2.3 I measured boot time of the camera from swithing the main dial until the AF symbol appears in the viewfinder without memory cards to be <0,5 seconds with SD card only to be...

Dear all! I have a question about downloading of photos from my 5D3: For security purposes, I recently switched to recording raw files to SD and CF simultaneously. You never know. So my photos are stored as "_MG_4286.CR2" on the SDCard "_MG_4286.CR2" on the CFCard When I download the photos...

Dear all! What are acceptable storage conditions for lenses in terms of temperature / humidity? Is it safe to store equipment, lenses in particular, at 20-25°C and 60-68% relative humidity without having to fear fungus in the long term? Canon usually do not specify storage conditions, just...

Dear all! Just a quick question: I set my 5D3 to a minimum shutter speed of 1/125, autoISO, and this works for non-flash photography in Av and P mode. Putting a speedlite on it, the camera overrides this and drops the shutter spped slower (1/60 or slower). (I know this is how it is ment to be...

Dear all, I am looking into buying an A3+ printer. Has anyone any comments to make about a sub-Pixma-PRO printers? The printer PIXMA iP8750 is a good deal cheaper than the PIXMA PRO 100S and it comes with 6-ink system, i.e. besides the text black has the usual CMYK plus a gray ink, so it is...

Dear all! My problem: I want to capture tiny tiny droplets (a few dozens micrometers) of a fluid which are moving quite fast. I know this will be a difficult task, this will be at the limit of the resolution of the lens and the sensor, The droplets could turn out as small as a few pixels in...

I spend a lot of thought into lenses like those, I mean around f/2 sort of apertures. With the fantastic 2.8 II zooms, I somehow don't feel the need for a prime that is only one stop faster, even if it has good IQ. So, I decided for myself I would get primes only if they are 1.4 at least, and to...

Dear community! I have an Olympus microscope and I want to take images with it, to be precise through it's camera port. So I attached a microscope ==> T2 converter to it and further a T2 ==> EOS converter to it. My EOS 5D shows vignetting, as expected, but my 60D works superbly, I can shoot...

Hi! Anybody heard of the possibility of adapting the TP-Link router TL-MR3040 into a 3rd party wireless file transmitter WFT? According to http://dslrcontroller.com/guide-wifi_mr3040.php it works with an Android camera controller app "DSLR controller", but I have no information whether it also...

Hi Everyone! I've got a question: I've never shot video before, but I would like to start doing so, for the beginning without a rack or any specialised equipment, really mainly to try it to see whether I like it and have talent, or rather not. I understand that I'll want a stabilised lens for...

Hi all! A question to all the users of the TS-E 90 lens: Is the shift function useful in this lens? According to calculations, a full shift on this lens only corrects for some 7° of converging lines. Is that important or even noticeable? (Obviously shift is important for the wide-angle TS-E-s...
