EOS Bodies - For Stills / Re: Would I benefit from going full frame?

Except for sports or bif, the 5D MK II is a great camera.  I stopped using my 7D except for product photography and macros in favor of the 5D MK II.
If you do low light photography, its a big step.  I am pretty unhappy with the 7D even at ISO 1600 its weak, while I get better images with the MK II at 3200 and even 6400.  I'm hoping to get 1/2 or better additional stops with my new 5D MK III, but I have yet to really give it a heavy duty test.

Hi,
    IMHO, every element added will decrease IQ by a bit, so a lens without IS will have slightly better IQ than lens with IS (when both lens are from the same generation and same grade) under perfect shooting condition.
So you believe a lens with one element is sharpest?  Maybe one with no elements is the ultimate?

Third Party Manufacturers / Re: Nikon Sales Rising
« on: November 07, 2012, 06:21:35 PM »
We have a small local Camera store which is actually run by photographers.  They sell both Nikon and Canon.  The owner tells me that Canon is much better to deal with than Nikon.  As a result, he sells more Canon Cameras even though he is happy to sell you Nikon if he can get it.  He did get a D800 for me, its a nice camera.  Lenses and service are a different story.
I'm back to a 5D MK III, its just much more usable over a wide range of applications, and I use mine tethered to a pc for product photography a lot.  Nikon loses big time there.

But, actually, I missed the point about the shorter MFD of 20 cm that I just read in the description, vs. 38 cm as stated in the Canon specifications.  Thanks for pointing that out!

Let's think about the practical implications.  An MFD of 20 cm, with the Canon flange-focal distance of 4.4 cm and a lens that when extended to 70 mm focal length is 12 cm long (DPR's spec is a little longer, I subtracted for the part of the mount that extends behind the flange).  So the working distance of the bare lens is ~3.6 cm, and if you put on a Canon EF 25 II extension tube (which is actually 27mm long), your working distance is 0.9 cm, i.e. to get that almost 1:1 magnification, your subject is less than a finger-width from the front element.  Yikes!  H-IS for longer exposure or not, with the apparent light loss at high reproduction ratios, it's going to be pretty hard to use this lens for macro.
A Kenko 1.4X TC might be better than tubes for a lens like this if you want macro.  I'm not recommending it, but putting the objective a fraction of a inch from the subject makes it very difficult to illuminate and easy to get squashed bug on your lens.

Canon has not been selling refurb 5D MK III's.  They usually let them pile up for a year or so.  The Used cameras that B&H sells are not Canon refurbished.  We may see Canon refurbished 5D MK III bodies at B&H, and Adorama before they appear on Canons site.

Exactly. The 70-300 L was released two years ago, yet it only showed up on Canon's refurbished site a few months ago. Some products, mysteriously, never show up on the refurbished site. For example, the 200 2.8 L prime (which is more than 16 years old) is never listed, even though there must be thousands of them out there that would be good candidates for refurbishing.

Although the 5DII was listed on the site for a couple of years, it has really only been consistently available within the last year.

Point being, there is no consistent or predictable pattern for what gets listed and when it gets listed.
I asked them about when and why a product is added to the site.  Basically, what they told me was that they need to have a very large number of refurbished items in stock to list it.

So, a very slow selling lens like the 200mm f/2.8 will likely never appear.  The refurb lenses are usually display models or new returns, and thats a lens you seldom see on display.  Any refurbs will likely go to stores like B&H.

Lenses / Re: 35mm lenses vs 24-70
« on: November 07, 2012, 05:52:05 PM »
The 35mmL is fantastic. but, as with any wide aperture lens, the depth of field at f/1.4 is shallow, and a slight error in focusing can make for a fuzzy image. 
If your camera does not have AFMA to fine tune the autofocus, you might actually be happier with the new 35mm f/2.  The price is a little less than I expected.
However, I do not expect to sell my 35mmL, its fantastic, and very good even at f/1.4

Check Thomas Distributing in the USA for batteries and chargers.  The charger is very important, the el cheapo ones can ruin expensive batteries in just a few recharges.  Battery makers love them.

I've seen them discounted already.  They are in stock in most stores too.  They will likely become scarce before Christmas, since many will buy them come black Friday.
Call a dealer (Don't e-mail) and ask for a discount.  You might be suprised.

EOS Bodies - For Stills / Re: 60D Microfocus Adjustment on FoCal
« on: November 07, 2012, 05:33:40 PM »
I've only done 2 lenses so far, my 85mm 1.8 (which comes up with a different number, near zero, each time) and my 50mm 1.4 that won't calibrate at all.

Lighting I think is an issue, but the mac beta says sorta weird things about iso, so who knows . . . not a lot of time on my hands :)
For lighting, I learned the hard way not to use CFL or Fluorescent Tubes :)
They drive FoCal nuts!
I use 98 CRI T8 tubes with a electronic ballast.  Works perfectly.  Just don't use the old non electronic ballasts.

it seems all of canons sharpest lenses have no IS.
is this co-incidence or is it because the addition of an IS system somehow negatively affects image quality? ??? ?
I do not believe that is accurate.  The newest lenses are the sharpest, and most have IS.  They have a more complex optical formula, and cost more as well. So what is true, is that newer lenses are sharpest, and prime lenses of the same generation and price range are usually sharper than a zoom.

It might end up being a kit lens, they knock off 200 or 300 if bought with a body.  The 24-105mm L is a better kit lens imho.

Lenses / Re: Canon Announces New Lens Caps!
« on: November 06, 2012, 09:15:25 PM »
Now how about some nice redesigned lens caps for the super-teles!!!
I'm sure that everyone would go out and buy them up at $250 each.

Your estimate makes the actual price of $120 seem like a bargain.  ;)
And... to think that I was exagerating so much that I thought I had listed 5 or 10X the price.  However, I know what the hoods cost.  I had a extra hood for my 600mm f/4 that I sold after the lens was gone.

Mt Spokane,  where can you get the shutter count on FoCal.
I use FoCal Pro, the feature might not be on other versions.
Here it is for my 5D MK III when I first received it.  It had only 23 actuations, most of them FoCal when this was captured.

They do play with the Canon SDK quite a bit, there are a huge number of undocumented features.  Thats how they are able to display the number of shutter actuations.  It wouldn't suprise me if they could do it.
