Lenses / Re: The 24-105 and/or the 24-70 II ...
« on: November 09, 2013, 10:24:01 AM »
I got my 24-105 as part of a 5DIII kit, not long after I bought the 24-70mk2. My initial plan was to sell the 24-105 to post-finance the 24-70 but while I was preparing the ebay auction i realised i had a good copy and couldn't go through with it...

Now I use the 24-105 as a travel lens for those holdiay destinations where I would be overly nervous having both  the 5d and the 24-70, my stuff is insured but I'm a risk averse kind of guy... 

I don't know if that really xounts as a reason to keep the 24-105 , but it's the one I'm using at the moment..

My googling skills must be getting rusty , as that Chuck Westfall Tech Tip would have cleared it all up for me...

Thanks 87vr6!!,

That make sense . i like your explanation of the aperture as " *apparent* size of the lens opening as viewed through the front" , tech resources on the net talk about entrance pupils and the like, which is all well and good , but every description of these terms has been far too technical for my limited optical  vocabulary!.

Lenses / Question regarding constant aperture lenses.
« on: January 23, 2013, 04:14:31 AM »
Hi all,

I have a question that is of no consequence and will not change in any way my photo skills ( it'll take more than that.. )  but nevertheless it occupies my mind...

First , to provide some background to my (mis)understanding  ,  I understand a lenses aperture expressed by it's f-stop to be something like  focal length / aperture . OK all good.

But , when a zoom is constant aperture  , the focal length changes throughout the zoom range ... So how does the aperture change to maintain the F number ?  , I.e after using a 70-200 2.8  ,@ 200mm  does the aperture max size suddenly become a lot smaller when moving towards the 70mm end ??.

I hope i have made my question clear...
