Also, it only happens on my work PC currently (windows 7 x64).

Does not occur for me, tried with IE8 on a Win7 x64 laptop and a Win7 x64 virtual machine (VMWare) on a Mac.

Does part of the down payment on a new vehicle count as 'fun'?   :P  I suppose not, but then, I fund all my gear purchases from 'on the side' consulting work - the day job income (and taxes refunded from that) go toward the important stuff - house, cars, kids' college and retirement funds, etc. 

Lenses / Re: Focusing on L lenses vs LII
« on: January 17, 2013, 10:46:46 AM »
With the series II lenses they report the serial numbers and will retain AFMA settings for each serial number.

Not all 'series II' lenses.  The serial number reporting is a feature of newer lenses only.  The 16-35 f/2.8L II doesn't have it, but the 600mm f/4L IS II does...and so does the 40mm f/2.8 'pancake'.

But it's still possible that's what the Canon tech was talking about.  In many cases, Canon tech support doesn't know what the heck they're talking about (e.g. the recent thread where they repeatedly claimed the BG-E13 grip for the 6D had a multicontroller on it).

Lenses / Re: Fast lens for indoor use
« on: January 17, 2013, 10:41:34 AM »
Looking for a fast lens, mainly for indoor(with low light) use. It will be used in family events, indoor parties at night and its usage will range from single to group portraits.

In those situations, I almost always reach for my 35mm f/1.4L

EOS Bodies - For Stills / Re: How are the AF points numbered on the 5D3
« on: January 17, 2013, 10:35:55 AM »
You could take a series of shots, manually selecting each AF point and looking at the EXIF, and then tell us...   ;)

Not sure if it's the same, but FoCal numbers them from the right side of the lowest row (in true programmer fashion, counting starts at zero) and rastering upwards - see the parenthetical numbers below (and note that these are for the 1D X, but I'm sure the 5DIII is the same).  It seems likely that your plugin is using the same scheme - not sure what your selected points were, but the points you mention (19, 29, 30, 35 and 41) are the five points in a '+' configuration in the center (i.e. center point with 4-point expansion).

Lenses / Re: 2013 - The Year for 400mm Lenses? [CR1]

You might, just might, be able to find a beat-up old EF 400mm f/4.5L for $3K.  If you honestly think a new 400/4L IS will be under $5K, you should see a psychiatrist for a diagnosis, or possibly a rehab clinic to flush out some illicit narcotics...    ;)

Did ever Canon made an EF 400/4.5L? I can't find it anywhere, Canon Camera Museum has no references.

In the '80s the FD 400/4.5 costed slightly less than a third of the FD 400/2.8. Thereby I guess it could be possibile today to deliver an EF 400/4.5 in the $3000-4000 range, which would make it cheaper than the DO. If it could have enough sales it's another matter.

You're right - I was thinking of the EF 500mm f/4.5L.  Thanks for the correction!  I doubt Canon would release an f/4.5 supertele lens at this point, given the reasonable assumption that most would want the option to use a TC, and that would require an f/4 lens for AF to work on most bodies.

By the way, I know some people may have issues with the Manfrotto QR plates (the fact that the system wobbles even when locked in) but I think the bigger problem is the friction lock on the ballhead- so even if you switch out the QR plate for an Arca-Swiss style mount you don't resolve the main issue.

I had minor issues with both, actually.  I started with the 488RC2 ballhead, and that head 'settles' under load (you need to 'aim high' to compensate, by a varying amount depending on the lens), plus there's the issue with the RC2 plate being loose even when locked.  The Manfrotto 468MG hydrostatic head solves the issue of the settling ballhead - that thing locks tight, and with minimal effort.  Replacing the RC2 clamp with a Wimberley C-12 solved the plate issue, resulting in a very good ballhead. 

Still...a 468MG plus Wimberley C-12 combo is over $300 new, and that's pretty close to the Really Right Stull BH-40 at $375.  I bought the 468MG used for a great price, but IMO, if buying new the BH-40 would be the better way to go.

FWIW, I am actually selling my Manfrotto 190CXPRO4 and Arca-Swiss converted 468MG - the buyer is due to show up in less than an hour.  Nothing 'wrong' with the setup from a support standpoint, I'm selling it because I want something shorter as a travel tripod.  The 190CXPRO4 fits in my Storm im2500 carryon hard case, but barely and only with the head removed - I wanted something that would fit without removing the head, and not compromise stability.  Not coincidentally, a Really Right Stuff TQC-14 with BH-30 LR is on a UPS truck for delivery to me this morning.  :D  The RRS setup is much shorter (tripod + ballhead are shorter than the 190CXPRO4 legs alone), lighter, the same height with the center column down, and is substantially stronger.  How much stronger?  The legs are rated at 25 lbs, but to give you an idea of how conservative RRS' support ratings are, check out the video where RRS owner Joe Johnson puts a medium format camera on the 25-lb rated tripod...then swings himself from the legs).

you mentioned the knob for the kirk clamp should go under the lens I believe... wouldnt that mean my QR plate would have to go sideways?
Please see my set up attached... have I done something wrong?

Just looks like you have a different style of QR plate than the norm (at least, from what I've seen).  Most camera plates are oriented 90° to how yours is oriented.  The key point, IMO, is that the knob doesn't stick out from the back of the camera - that would make it more likely that you'd be rubbing the know against your leg (and also more likely that you'd bang youself in the mouth or chin with it, so I suspect you'd learn to orient it differently pretty fast!).

What kind of plate do you have?  Normally, the dovetail grooves are oriented 'sideways' so that when you clamp onto a tripod, the knob/lever on the tripod head clamp is oriented to the back for easy access, rather than having to reach under the camera.

Lighting / Re: AF assist for outer focus points on 5D3?
« on: January 16, 2013, 10:38:50 PM »
I previously tested the AF assist lamp coverage of the 430EX II with the 61-pt AF system of the 1D X (and 5DIII).  With a focal length of wider than 35mm, the outermost columns (which are f/5.6-sensitive lines) are outside of the coverage area.  At 35mm and longer focal lengths, the 430EX II's assist lamp covers all 61 points. 

The 600EX-RT provides full coverage, of course.

Buy all three seriously.

I did...   :)

I assume I have to convert the focal length of a lens on my APS-C camera to the effective length when inputting data to a calculator (such as inputting 80mm as focal length for a 50mm lens on a 1.6 crop factor camera)?

Most of the tools (including the ones I linked), you select the camera you're using.  In that case, you don't 'convert' the focal length, you use the actual focal length of the lens.

Canon General / Re: Why buy from a bricks and mortar store?

I totally agree with you neuro, but where is the line drawn for what must be declared on taxes?  Purchased on eBay (new or used)?  Craigslist?  Garage sale?  What is the letter of the law?

In most states, all of those sales are subject to Use Tax.  Likewise, if you sell something on eBay/CL for more than you bought it for, tecnhically that represents income and should be reported as such (but the reverse, selling for a loss, doesn't entitle you to a deduction). 

Disclaimer: consult your tax adviser...   :P

...if this 501 plate system is arca swiss compatible, it sounds like it would be the way to go..?

Sorry, but it's not.  The 501PL and 504PL plates used by the two B&H items you linked are interchangeable (the 504 is a longer version of the 501), but they're compatible only with certain Manfrotto heads.  If you want to convert Manfrotto 501-compatible heads to work with Arca-Swiss plates, you need the Kirk SQRC-501PL ($150).

Reviews / Re: Review - Canon EF 70-200 f/2.8L IS II

I'm pretty torn between this and the new Tamron 60-200 with VC. True, not bi directional and 4 stop VC but it is black AND 700 dollars less. Haven't found too many articles and comments persuading me to go with Canon...

How about the difference in sharpness at 200mm? They're similar at the short end, but the Tamron 70-200 VC appears significantly worse at the long end.

I use the free Field Tools app, works well.  I also use Photo Aide ($2), which does FoV calculations (and others) in addition to DoF.
