Third Party Manufacturers / Re: Crazy... go Nikon?

Everyone will jump ship?  Wow!

I count three people here who have switched or gone with dual systems.  I think Canon has sold at least 6 cameras, so no more than 50% have switched.  ;)

aside from the three mentioned, what is your total investment in EF-S long glass? what long glass do you reach for when needed?

I was wondering, just how much can you invest in EF-S long glass?  (Or, perhaps, how do you define long glass? ;))  The 55-250 is the longest EF-S lens offered, following the 18-135.  Everything else tops out at 85, I believe.  EF-S lenses are designed to give croppers the FOV of wider EF lenses.  There is no demand for long EF-S lenses, since people use long lenses to "reach."  I mean, who would buy an EF-S lens with the FF FOV of the 100-400 when they can use the 100-400 perfectly well and get 1.6x the "reach"?

 I know what you mean, so not to pick nits here but to be more precise I would state the objectives of EF-S this way: 

1.  one of the primary intentions of the UWA EF-S lenses is to give the cropper the FOV of longer EF lenses when used on FF bodies.  (10mm on a APS-C gives the equivalent FOV to the longer,  16mm on a FF).

This is what I meant when I said EF-S lenses were intended to give crop users the FOV of wider EF lenses, the wider EF lenses being those around 16mm.  So we agree.

The Adobe site has many video tutorials on using both PS and LR.  They also have public forums for users with questions.  And they are all free.

The APS-H is a compromise for everyone.  Those who want "reach" don't want to drop down to 1.3x, and those who want FF benefits don't want to, well, drop down to 1.3x.  It should die.

Interesting conversation.  I don't have the 70-300, but I have used the 100-400 for six years, on a variety of crop bodies.  As suggested by others, this is great for birds, which is about all I use it for (although I shoot a lot of bird pics).  My copy is razor sharp at 400mm,  which is where I have it 99% of the time.

While true that you have 480mm FF equivalent reach with the 70-300 on a crop body, you have 640mm equivalent with the 100-400.  For serious birding without the money for a prime, this difference is substantial and worth any hassle stemming from the greater weight of the 100-400.

Rumors about a new 100-400 are very interesting, and if that pans out it will be what I replace my current long zoom with.
