Nice article Dustin and it's pretty amazing what the combination of new technologies (high ISO bodies) and old ones (polarizers) can achieve in the right hands.  I liked the photos as well and think the jellyfish one turned out really well.

The High ISO performance of this current generation is really pretty stunning.  If another stop or so can be gained in the MKIV of the 5D line or the 6DII, it really changes the game.  If you could treat ISO 12800 or even 25600 like you do 6400 now...wow!

The downside for the manufacturers is that photographer's need for primes is dropping.  A two lens kit of a couple f/2.8 zooms (particularly with stabilizers) really covers most every need.  Primes offer more creativity and flexibility with shallow DOF (and I love them), but I'm going out of the country to shoot a wedding next week and am only packing a 24-70 and 70-200 f/2.8 zooms.
I know and I hate to see the new lenses coming out with slower apertures because the shallow DOF is what makes [D]SLR photos so unique and different from compact cameras and phones.  I hope the camera companies realize that this is the one Me_Me_Me card that they will always hold over camera phones :).

I agree.  That being said, if a genuinely sharp wide open 50mm f/1.8 IS came to market (with the modern reduction in CA, etc...) along with curved aperture blades, I would take it over the 50mm f/1.4 all day.  I actually own the newer 35mm f/2 IS and it is a fantastic lens.  I rarely find myself wishing for a wider aperture as it is so completely usable wide open and the DOF is already pretty shallow.

I would be interested in a 50 f/1.8 IS as well, but find that the 50L does extremely well at portraiture, which is what I use it for 95% of the time.  I have heard great things about the 35 f/2 IS and would definitely like to try one out.  As the only Canon IS lens under f/2.8 that costs less than $5k, it's always intrigued me.  Have you reviewed it or blogged about it on your site?  If not, I'm sure more than a few of us would be interested to read your take on the lens.  I don't think I've seen a real-world review of it by anyone - just the usual charts and graphs...

I've got the review about 85% done, but it's been on the back burner recently.  I need to get it done!

I completely understand - I have a number of things I've promised people here and elsewhere, but we'll eventually get to them.  I look forward to reading your review when you complete it :)

Dustin,

Great idea and nicely written article. I'll have to try this the next time I'm at the national aquarium in Baltimore.

Would you mind posting the ISO, f-stop, and shutter speeds of some of the photos you took?

Thanks again!

Vivid

Most all of the shots are in the ISO 10K-12.8K range.  Shutter speed is typically around 1/100th second, and all of the shots are wide open in terms of aperture.  With the 70-300L, however, that means that at best it was usually f/5 and more typically f/5.6.

Thank you, Dustin!

No problem.  The great high ISO performance of the 6D makes the 70-300L a viable option in what would have previously been unfavorable conditions.
