Any chance there has been an update to include the 1DX?

Not yet.  Their website now indicates (which it didn't a week ago) that support for the 1D X, initially with ~30 lens modules, is expected in October (except the 40/2.8 pancake which is due in November).

I'm actually thinking of running everything that requires NR through lightroom, then going into Aperture for lib management and further manipulations.

I generally do my RAW conversions in DxO Optics Pro (which handles NR and lens corrections very well), and use Aperture for library management.

No, you shouldn't have any issues with banding.  I'd look at the B+W Slim (not Käsemann, not MRC, just plain), $90 at B&H, or the Hoya HD ($135 but not in stock at B&H).  But, do keep in mind that putting a low quality filter in front of a high-quality lens defeats the purpose of getting a high-quality lens...

Depends on your bank.   ::)

I use a B+W Käsemann CPL, it's excellent although mainly I use it on my TS-E 24L II, less frequently on my 16-35L II.  Do be aware that if you're using it on FF, in much of the wider part of the 16-35's zoom range, those deep blue skies you yearn for will not be evenly deep blue.  At wide angles (starting at ~24mm on FF), a CPL will produce uneven polarization (banding in the sky).

According to the manual (p.33), if all 3 lamps blink green, you should remove the battery and call Canon Service.

What we really want to know is how many of the 80million are L series lenses.

Lots of them.  But not aLL of them.

- Next thing I realized, for NJ, you pay sales tax! That's like another extra $400, bam, right there it hit me.

Ummm...you do realize that you're legally obligated to pay the NJ Sales and Use Tax on those Amazon purchases, right?  From NJ Pub ANJ-7: "Out-of-State Purchases Delivered to New Jersey. When taxable goods and services are purchased in another state and delivered to New Jersey for use in New Jersey, no credit is allowed for sales tax paid to the other state. Use tax is due at the rate of 7% of the purchase price, including delivery charges.

You're supposed to declare such purchases and remit the tax to the State, either separetely within 20 days or on your state income tax return.  Bam, right there.  Just sayin'.

- 50% of my shots were below 38mm.  That means that on a crop the 24-105 would not be useful since its really (38.4-168).
- 26% of my shots were below 27mm and 15% above 88mm.  That means I would of lost those 41% if I brought only 17-55.  Or would of had to bring 3 lenses to compensate. (10-22, 17-55, 70+)
I'm not sure, but the fact that you're using 27mm and 88mm (1.6x 17-55mm) suggests you may be suffering from the misconception that EF-S lens focal lengths are somehow 'corrected' for the 1.6x crop sensor.  They aren't. 

The 24-105 on 1.6x does go below 38mm...it starts at 24mm.  In other words, setting 24mm on an EF-S 15-85mm on APS-C gives exactly the same angle of view as the 24-105mm set to 24mm on APS-C.

If you want to compare EF-S vs. EF lenses used on the same camera, don't mulitply anything by 1.6x.  You only do that if you want to compare a lens (EF or EF-S) mounted on APS-C to a lens mounted on FF.

Lenses / Re: 100mm f/2.8L IS vs 70-200mm f/2.8L IS II for Macro
« on: August 23, 2012, 09:25:17 AM »
The 100L looks sharper in the corners to me on the TDP examples, obviously more vignetting, but slightly sharper. So that tends to make me reject both DxO and photozone testing.  :o  But all of this also tends to make me want to buy a 70-200 II since I'll never spring for a 200 L f2...

I do think what we're seeing is within the range of copy variability - if you look on TDP, he tested three copies of the 70-200 II (there's a popup menu so you can compare them).

I think the bottom line is that while there may be differences between the two lenses from a sharpness standpoint, the direction and magnitude of that difference is probably subject to lens copy variation.  Most importantly, both offer excellent IQ that's probably not distinguishable in real world shooting. 

So, IQ shouldn't be used as a distinguishing factor between these two lenses...it really comes down to whether you need to go to 1:1 magnification or not, whether you need the flexibility of a zoom, and what your budget will cover.

Is the issue with pictures taken with the 40/2.8, or with transferring images while the 40/2.8 is mounted even if the 40/2.8 wasn't used to take the pics? 

It's been a long time since I've connected a camera to my computer for anything other than FoCal calibrations, and for that I direct it to the Win VM running on my Mac.  But...doesn't the camera show up as a mounted disk on the desktop (the CF/SD cards in a card reader always do)?  If so, can you drag/drop the images from the 'disk' to your internal drive?  You could the import them to Aperture from there...

Both of my D5100s are off by nearly 1 degree in the same direction!  I didn't notice it for a while until I started shooting some water scenes.  I wasn't using liveview and the on-screen gridlines as I was trying to conserve what was left of my battery for more shots. So I leveled the water horizon carefully to the outermost AF points.  All those shots were consistently clockwise from level by about 0.8 degrees.  ARGHH! I've yet to send them in to see if they can straighten them out, likely the reflex mirror is a bit tilted as everything else seems to be optically well aligned. 

Minor random point, but it's unlikely to be the reflex mirror (light for AF passes through portions of the reflex mirror that are beam splitters).  Most likely, the focus screen is not straight - could be the mounting bracket is off, or the screen isn't seated properly.  Not sure if the D5100 has a user-replaceable focus screen, but if so, you could try adjusting that.

What if you are not shooting with a tripod?

Try to hold the camera straight.  :P

Actually, that's what's really convenient about the electronic level - it can be displayed in the viewfinder.

Some newer cameras have an electronic level, which is very convenient.  Before I could use that, I used a hotshoe bubble level.  I have this one, there are many available...

The bird is a Bank Swallow (Riparia riparia)

But is it beating it's wings 43 times every second to maintain air speed velocity?  And is it carrying a coconut?  Regardless, I think it looks more like a robin.  A brave Robin running bravely away. 

Ok, I'll stop before someone turns me into a newt, or farts in my general direction.
