I made a career out of testing complex computer security devices... believe me when I tell you I know how to test stuff.... ;o)

Good idea re astronomy club... but I can't really wait for that given short return window on this equipment....

No cold. No moisture. 70 deg or more

ISO increase was purely to counter the 1 stop difference in max aperture

In other words, our exposure setup was identical, yet he needed 20secs and I needed 45 secs to get comparable results. And his camera could see the light painting effect whereas mine could not

So... was the lens ACTUALLY opening to f4 or stuck on smaller aperture? That is something I need to test. Also swapping lenses and going for same exposure at same f stop with different lenses. I will test. I am a scientist so OK with how to test for faults. What I am hoping for here is some "ah ha" moment from another Canon user, preferably 6D

You said everybody was shooting f2.8 lenses and you were shooting f4, might the lens be the culprit?


That is one of the questions I am asking, yes. Clearly either camera or lens is at fault. I really wish I had tried a different lens... but I didn't. I will be doing additional night tests at home to try and narrow this down. Thought it was worth asking here to see if other Canon owners have had similar experience with e 6D

Just purchased a 6D so getting to know it. I took it to Big Bend to photograph the Milky Way last week and though I got some nice results I struggled with the camera. Lens was the f4 11-24mm zoom.

I was shooting alongside 2 Nikon owners and a Canon 5D MkIII owner. The Canon owner, being experienced at night photography, was helping me with exposures. He said the sensor on the 6D should get better low light results than even his.

Here's the issue.... everyone else was shooting at ISO 3200, f2.8 for around 20 seconds. I bumped up to ISO 6400 to make up for the extra stop (f4) but ended up with exposures of 45-50 seconds just to get results comparable to the others. When they tried light painting, they were getting some amazing results (brief 1 second flashed from LED lamps on the foreground) but my camera picked up virtually none of it.

So on the face of it, my sensor was WAY less sensitive than any of theirs. I had long xposure low noise reduction set to Auto, by the way... only on certain shots did I get the long delay as it wrote to memory card so clearly it was being used occasionally... there was no discernible difference to the exposures or results so I doubt that setting was the culprit.

So..... any ideas? Faulty camera? Faulty lens? Settings I need to look at? Or is the 6D just really bad at night photography (not something's no I would have expected based on reviews)?

Would really appreciate some help, especially from other Canon owners. REALLY not looking for "switch to Nikon" type advice, thanks :0) I need to decide quickly if I need to return camera, lens or both, or if I can fix this via camera settings

Thanks in advance

I guess you should be familiar with many file systems e.g ext2 , 3 , 4 xfs ReiserFs zfs and others each tend to have different strengths and weaknesses e.g XFS is good for fast disk access ext3 and 4 are journaled so if there are problems the journal can be replayed. I guess you would know why reiserfs is currently unsupported ...

As a journalled filesystem NTFS is much more robust than exFAT exfat has advantages for solid state drives less writes and less wear but fud for a well established mainstream file system such as NTFS seems remarkable. Personally I would just use hfs+ if it's primarily going to be used with a mac and just use a network share for PC use. File system protocols are widely understood you should know this. We pretty much should have similar experience but i have a feeling i've more familiarity with cross platform issues.

Well I find much of that a little condescending but will let it pass - this is why I tend not to post on forums.... There is no way I wanted to get into deep explanations of different file systems as part of a post on a photography forum. My point when dealing with laymen is always KISS....

When we are discussing external storage to allow you to get pics off a memory card while on a trip without having to lug around a computer then lowest common denominator is key. Journaled filesystems are all well and good providing they are supported. You are dealing with cobbled-together storage systems that are cross platform in more than just the Mac/PC world - weird little Chinese widgets and phones are suddenly part of the ecosystem. I found a solution that worked well and just wanted to post my experience of that... If you are happy lugging around high-end laptops with external RAID storage on your vacations then more power to ya....

Paragons ntfs driver version 12 is good up to yosemite and is free but newer than that you need version 14. I have never had an issue, they just work.


My point it they all work up to the point they don't.... and they will all work again eventually. But that is of little use if you are stuck with no access to your data.

As an IT professional and security guy of over 35 years I am of the KISS school of thought.... unless you NEED NTFS, then format with ExFAT

Or not... that is just MY personal 0.02....

ExFAT is great. I've never had a problem with it on *newer than 2013* devices.


And I have also had NTFS drivers on the Mac that worked fine until the next update.....

No perfect solution here! LOL ;o)

See thread elsewhere - always format your external drives using ExFAT to ensure cross platform compatibility

That one uses NTFS and includes the drivers for the Mac... works fine if you want to trust the drivers.

I bought it and reformatted to ExFAT regardless....

Us ExFAT.... that works seamlessly on both Windows and Mac

OR you CAN use NTFS, with add-on drivers for the Mac

I had occasional problems with NTFS drives on Mac in the past so I use ExFAT exclusively on all my external HDs now

I just bought a RAVPower FileHub Plus on Amazon for $40. It is small and light-weight, it has an SD card slot and a USB port for a thumb drive or external hard drive, and it doubles as a wireless travel router and a 6000mAh external battery pack. You control the file transfer with an app on your cell phone, and you can view your pictures on your cellphone to verify successful copy. I've tested it a couple of times and it seems to work as advertised. I've purchased several other RAVPower electronic items in the past from Sunvalleytek via Amazon and have always been impressed with the quality of their products and their customer service.

Just bought same following recommendation from someone else on here. This is a great compromise because a) you get to use multiple drives/USB sticks so can make multiple redundant copies, and b) you can examine the file structure and contents using your phone to ensure everything copied over OK before erasing your cards.

Bonus - it is an external battery to charge your phone, etc. on the go! Also portable wireless access point if your hotel room only has a wired Ethernet connection. Small enough and light enough to put in your camera bag. I pair it with a couple of super slim, super light Seagate 1TB/2TB drives.

Care to share where to look? I've been paying annually for years at $120/year. A bargain, but I hate leaving money on the table if there is a better deal. (legal, but better deal)

Yes, sorry, of course! Lol

I bought a Photoshop/Lightroom course from CreativeLive and there was a link to subscribe for $8 and change on there. You will have to dig around in their various course offerings to find it, and it is not terribly prominent. But if I remember correctly you didn't even have to actually buy the course to use the link

For the software I use on a daily basis I would always tend to upgrade automatically whenever new versions come out. You get stung for upgrade fees, and my gut feel is that I spend the same or less subscribing to the Adobe software. I pay $8 a month for LR and PS... there ARE deals to be had if you know where to look

This thing does it all. You control it with your phone, using wifi, through a free app. It has a card slot and a usb connection for a hard drive. Or, with a usb adapter for another card, you can back up to it.

Just researched it on your recommendation and bought it on Amazon for under $40 - arrived today. Works like a dream. I have numerous small 1TB external HDDs that I have accumulated over the years for backups, so this is the perfect solution. The external power pack and WAP/router features are icing on the cake.

Thanks for this!
