Software & Accessories / Re: Flash for FoCal - Anyone try it?
« on: August 14, 2013, 01:06:20 AM »
Two simple work lights 250W each (less than $30 at home depot) worked for me, if you don't have other lamps that qualify and double as desk lamps.

Flash would not help the AF and focusing would be inconsistent because of low light as the flash fires after focusing

You might find this interesting: http://www.lensrentals.com/blog/2011/08/the-apocalypse-of-lens-dust

With or without visible impact on image quality, the owner will probably insist on having it repaired or replaced.

not sure what is going on, but if all the guy in the store did was using the power button, I doubt that you should blame him. Obviously a problem existed before, that's why you went there in the first place, didn't you?
It could still be a camera problem, even if it shows up only with certain lenses at certain focal lengths. There could be several minor defects that add up only under certain conditions - hard to tell without giving camera and/or to a repair center

I like that the collar is a good way for me to support the lens...  The focus and zoom rings are swapped compared to other common L-series zooms, and without the collar, my hand reaches for the 70-300L's focus ring almost automatically.  Supporting the lens by the collar foot places my hand so I grab the zoom ring by default.
btw, what lens plate do you use on the 70-300? I have the P20 but find it is almost longer than necessary. With the 5D it never is front heavy on a tripod, and when handheld the plate is a bit in the way when I grab the zoom ring, so I was considering a P10

The 70-300L seems like a great lens for me, ...
It is a great lens, but since you mentioned wild life and birds - even on a crop body it will feel too short many times.
Consider a 100-400, or the 400 f/5.6. I'm thinking about adding the latter to the 70-300L

Seems like the Blackrapid strap is the answer for me, but will the mount be able to take the weight? The 70-300L doesn't come with a tripod collar, so should I get one?

I always leave my collar on, I  would say it is with buying one,  but it doesn't have to be oem...  there are some decent knockoffs out there.
The Canon collar for the 70-300L is expensive. There are decent knock-offs (I use the Fotodiox with a Wimberley P20) that work well.
The camera lens mount could probably take the weight (see Neuro's example with the 85mm L), but it is much better balanced on the strap as well as on a tripod if you use the lens collar.

An alternative to a strap can be a shoulder bag that is tall enough to house camera with lens and hood attached - but you won't have the camera ready as quickly, and if you are already carrying a backpack with more gear, it is a little busy around the shoulders. I do it sometimes when I take camera and 1-2 lenses only and leave everything else at home.

I don't think you can do it more accurately manually

Lenses / Re: Best Filters for 24-105 f/4
« on: August 09, 2013, 12:37:01 AM »
A CPL for landscapes is pretty much standard.

To protect the front element of your lens, a UV filter or a clear filter. The sensor in a digital camera is not sensitive to UV light, so it doesn't matter which one you buy, so once you decide on a brand, just choose the one that is available or less expensive. For many lenses, a filter also completes the weather sealing. I'm not 100% sure if that is the case for the 24-105, but I believe so.
Btw there are two groups of users - the ones that recommend having a filter on the lens at all times to protect the lens, and those who don't. You will likely receive advice from both groups :-) I belong to the former.

Avoid cheapo filters as they will degrade IQ. B&W is one of the better brands. Try to get the Xs-Pro versions, they are slimmer than the F-Pro, so you can stack filters if necessary without getting too much vignetting. Avoid the "slim" version, they don't have front threads, and you lens caps won't attach to the lens anymore.

Edit: type

I just wish that Canon's wired remotes supported the function!

What do wired and wireless remotes do, revert to setting the focus with the shutter?
You actually have to set the Shutter button back to AF and AE if you want the remote to trigger the autofocus. Otherwise the camera will take a picture without focusing

I appreciate all of ya'lls help... but I'm not sure that I'm any closer to making a decision on the matter.
Something entirely different maybe? Lensbaby?

I have it on all the time, even had it on on my rebel. It took me a few afternoons to get fully used to it.
In the beginning I used to switch back and forth, but now I prefer to have BBF and AI Servo on all the time. If I need to lock focus, I just take the thumb off

if you are not sure about a lens to upgrade, why not invest in a trip to a great location?

Thanks Neuro. Fascinating how much gear can be attached to a camera in a useful way
