222 vs 66 is of benefit even if you don't immediately recognize it - if your first choice at LensRentals isn't available then you've probably got several other alternatives.
My statement regarding tilt shift was in reference to what LensRentals currently stocks.
Maybe Sony has many f/2.8 primes (Canon's non-L are usually f/1.8)but I've got Canon versions at f/1.4. Stabilization is easier and probably overall cheaper with Sony but I like seeing the effect through the viewfinder which i don't think happens with in-body vs in-lens stabilization. For the type of shooting I often do (low light action such as dance,sports, gymnastics) the larger aperture is of value whereas stabilization isn't due to subject motion blur requiring a shutter speed way more than the reciprocal of focal length anyways.
And the Best Buys near here carry the Canon L zooms below about $2k retail.
Canon's mid line flashes and above have tilt plus shift. Zeiss lens are available for Canon and Nikon as well but aren't as mandatory as there is good OEM glass available above the consumer line stuff.
I'm not saying that other brands don't have choices but there generally aren't as many or as easily available as for Canon or Nikon which is why I recommend staying more mainstream.
Seems you are making a lot of statements without actual knowledge.
Sony has a ton of 1.4 and 1.8 primes available. In fact, between new and used, there are 37 prime lenses available for Sony with aperture faster than 2.0.
Sure... Maybe Canon has 10 different 50/1.4s.. While Sony only has 5 different 50/1.4s. (Actually, I checked... Canon has 4 and Sony has 3 in current production).
But how many different 50/1.4s does a user need?
Of course... The big difference-- your 50/1.4 on the Canon probably isn't image stabilized. The 50/1.4 on the Sony is image stabilized.
And in terms of viewing the effect through the viewfinder, Sony is superior to all the other brands. Yes, you do see the effect of image stabilization through the VF... You also see the exposure, which you don't see on the other brands. Of course, the EVF is a negative to some buyers. To others, WYSIWYG is a very nice advantage.
Truthfully... There are times I've had some jealousy of other brands for some reason or another. Wish I had the high ISO performance of Nikon. Or the touch screen of the newer Canons.
But I've never had any reason to be jealous of lens selection.
In fact, Sony had some lenses that are unmatched by the competition. For example, there is a Sony 135 STF lens that doesn't have a Canon/Nikon equivalent.
To get a better sense of lens availability, B&H carries everything. They stock 244 Canon lenses and 116 Sony lenses. 116 is enough selection for anybody. For the most part, Canon has a lot of duplication (with VC and without VC models).
In fact, the only advantages I can see for Canon lenses-- they do have a couple 1.2 primes while Sony typically goes to 1.4. (Pretty tiny difference, and I'd rather have a image stabilized 1.4 than non stabilized 1.2). And Canon has a better selection of constant f4 lenses. (Sigma has a nice 24-105 f4 for all mounts, so technically it's no longer a Canon advantage).
For any amateur, and 99% of professionals, there really are absolutely no holes in the lineup of available Sony glass. With legacy glass being a real advantage for Sony and Pentax.
