Lenses / Re: 400 2.8L, 500 4L or 600 4L for wildlife

Has anyone had the opportunity to compare the 600 f4 IS with the MKII version with and without extenders?  From an IQ perspective, how much difference is there really (lighter weight and improved IS aside)?

A lot.  The 600 II + 1.4xIII is better than the bare original 600/4 (and also better than the bare 800/5.6).  Even with the 2xIII, the new 600 II is very good.

If I want to shoot daylight landscape with tilt-shift lenses and get amazing detail at low ISO's, I'll go D800. 

Except for that pesky 'PC-E 24mm control knob hits the flash housing' issue...

Jeez.  I'm switching to Nikon.

According to the data from Roger Cicala, if you'd sent a lens into Canon's Jamesburg facility just before Sandy, even with the >2 week delay from the storm, you'd still be likely to get it back faster than if you'd sent a Nikon lens to an open Nikon Service Center...and you'd probably have paid less for Canon's service, too...

There's a small hit on sharpness, but it's not bad at all.  Generally, the 600 II + 2xIII combo is excellent, IMO, as is the 1.4xIII.  Obviously, you only have the central AF point(s) with the 2x, and that can make tracking birds in flight a challenge.  Still...it's doable - the shot below is an American Bittern shot handheld, 1200mm, 1/1600 s, f/8, ISO 3200 (he was too far away even at 1200mm...).

i wonder about the Sigma's ability to relate TTL info to the flash if you were in fact in TTL mode on your flash

I think it's unlikely that Sigma lenses transmit subject distance data to the camera to support E-TTL II flash metering, which is something that Canon lenses do (the newer ones, anyway - for example, the original 85L does not, that was added with the MkII).

But in this case, it's not relevant - the distance data are ignored when the flash is bounced, which the OP stated was the case here.

Not quite true... people do not wish to pay the full price FOR AN OVERPRICED product.

Who defines 'overpriced'?  For some people, the 5DIII at $2900 was too expensive...for others, $3500 is not too expensive. 

The answer to my question is 'the market' defines 'overpriced' and that leads to low sales, which might lead to a reduction in the MAP.  But if sales don't drop much, or at all...

This is a very interesting accessory... if it works with a 430exII then it will get added to my kit, thanks for the tip and nice bird portrait!

Yes, they have a model for the 430EX II - the FX5.

You'll be better off with a more powerful flash in some cases (I have one for my 600EX II), but the 430 will work.  What's more important than flash power is getting the flash off camera - you'll want a flash bracket with an off-camera cord to get the light off the lens axis and reduce 'steel eye' (the avian equivalent of red eye). 

Also, take the fresnel lens off when not using it - it works both ways, and the sun shining down on your better beamer turns it into a better burner (fresnel lenses are used in solar backpacking ovens), and you can melt your camera gear or your skin, depending on the angle of the sun.

I was so upset - I had set a psychological limit of $3000 and was waiting for my annual bonus. I received it yesterday, only to see the price going up again... $300 more just because MAP went into force seems unreasonable at least to me

Unfortunately, that's life.  You can either wait and hope the price drops in the future or find an extra $300 and give in to temptation...   ;)

I don't see this having any significant negative impact on Canon's sales - and probably positive in the long run, since keeping their major retail channels happy is important in the long run, and unpredictable undercutting by discounters can undermine those relationships.

Agreed.  You very unlikely to find holiday shopping-related deals on these sorts of items.  That's not to say that prices won't drop a bit (although a rise is also plausible), it's just not going to be tied to the season.

Using Custom Controls, you can assign AE Lock to the shutter half-press (you can do that on the 7D, as well).

Lenses / Re: Can a UV filter affect IQ (sharpness) on a lens?

I want to know more about these flourine coatings by Canon. Neuro can you explain what that does? Does it mean we no longer need clear filters?

The fluorine coating makes cleaning the front and rear elements easier - it's the same stuff they use on the walls in urban centers, to make graffiti removal easier.  There is no protection against scratches, etc.

EOS Bodies - For Stills / Re: Is this an Overkill to purchase the EOS....
« on: November 02, 2012, 08:01:59 AM »
Since you plan on getting a supertele lens, I definitely recommend either the 5DIII or the 1D X.  The better AF and the ability to autofocus at f/8 will be major benefits over the 6D.  For shooting birds, especially in flight, and macro shots on windy days, the 12 fps of the 1D X could be a major benefit over the 6 fps of the 5DIII.

Problem is though...people on CR want to buy the bloody thing, but do not wish to pay full price (dilemma :-[)

Yes, people on CR want to buy the every bloody thing, but do not wish to pay full price

What else is news?  Why are we even discussing this?  Anyone who jumped on the lower price should be happy they had a bit of notice - it's like planning to sell a stock, and being told today that the share price will drop tomorrow.  Anyone who sat on the fence and must now pay more, it's unfortunate, but that's life.

Our eyes are like D800 where we can (naturally) pull out a lot of shadow details instantly.

Maybe your visual system is like the D800.  Mine has far more than 13.2 stops of DR, my 'raw files' are transferred and processed much faster, and image noise is nonexistent.  OTOH, image playback loses some of the detail...
