Hi lintoni.Duh! Should've checked your sig before posting!
Thanks for the thought, seller says battery is charged, but I have a 40D so would take a spare in pocket just in case.
Cheers, Graham.It might be worth asking friends if they have a camera that uses the same battery (BP-511) and borrow a battery, just to check that the camera works, if you do get your offer accepted.
Yep, as the previous posters said : for wide-field astro photo, you'll need a Samyang lens. They're pretty much the only ones to do wide aperture with almost no coma (maybe Zeiss too, but i've yet to see a test for coma with the 18/21mm Zeiss lenses).
The Canon 16-35 f/4L is mostly comma-free, but F/4 is really not ideal.
Thanks, this is great advice. Your sample pictures were amazing.
Is Samyang just making another version of the Rokinon lens or vice versa?
If I am going to buy another L, I'd rather get something I'll use more than the 24L at that cost.
I may have found a fix for the shutterbug (not sure).
The shutter bug always occurred when using the EF-M 18-55 IS STM lens.
I changed the Custom Function "Release shutter without lens" to "Enable", restarted the camera and the shutter bug was gone.
Since then I have not been able to replicate the shutter bug (not even by changing the setting to "Disable").
It worked for me. I am using the sept 27 nightly build.
What advantage would there be to have a liquid element in a sealed camera lens? Does light pass through clear liquids in a differnet way than solids?You can alter the shape of the lens, thus varying how the light's path is refracted by the lens.
I was using my 70-200mm today for softball... it would have been tough to limit myself to only 200mm... so I think I may be keeping the lens even if I do elect to upgrade to the 200 f2...What?!?
Surely UFRaw or RawTherapee can handle 5D3 files, no? The big downside in Linux is the lack of 16-bit final stage editing. GIMP is nearly there though.early 5D3 user, and there were no OS tools that could handle the raws from my new toy on my Linux PC.
16 bit GIMP is available, but only in development versions. You can try builds for Windows and Mac OSX from here:Surely UFRaw or RawTherapee can handle 5D3 files, no?

I use GIMP on WIN, 16 bit GIMP might finally get me to the Linux camp.
On WIN, UFRaw has always left me wanting, RawTherapee looks excellent in comparison though I do need to spend more time with it, just found it recently.
