Lenses / Re: Lots of New Lenses Coming in 2014 [CR2]
« on: November 10, 2013, 07:50:57 PM »
Lots of guesses here - mine are:

100-400 f/4-5.6 IS L II
50/1.4 II
85/1.8 II
28/1.8 II
35/1.4L II
The big macro will be 200 f/4 IS L
Maybe the two longer tilt/shift lenses.
24-105 IS L II STM
There almost has to be another EF-S zoom or two also.

I've seen some folks go with a 24-50-100-200, though that jump from 24 to 50 is pretty big.

Now that would be an interesting prospect. If it's a good quality lens.

I expect that it will be quite large though.

It'll be interesting to see how the 70D technology pans out. It looks like the AF capability is good. If this is applied to a new M class body, and if this new focal length "reducer" comes to fruition, this could be a versatile addition to the kit for someone that's already packing a good amount of EOS glass.

Looks impressive!

If the files are truly clean and not doctored to appear clean, then this might make a nice companion to the 5D3. I really like having two bodies, especially when I'm at an event and don't want to swap lenses back and forth. Having a nice, high pixel-density cropper alongside my full frame body gives me a lot of flexibility as well.

I'm here!!

New sensor sounds promising. Hope it's cleaner.

My 5D3 is lonely. :)

Side note - get the young one a Canon S-110!

The difference is amazing, especially at high ISO.

What is the H.264 doing to the image to destroy the contrast and brilliance of the color?

When I bought the Kenko (which still works fine), the primary purpose was to allow AF with an f/8 combination on the 5D2. I soon bought the 5D3 and found the performance to be very good with it at f/8.

I've also got my Canon 1.4X II and 2X teleconverters still - no need to get rid of them.

As for micro-adjustment - I just haven't taken the time to perform that function at all with the 5D3, though I probably should at least with my longest lens combinations. There are a lot of competing variables that conspire to degrade image quality when shooting with long lenses (camera shake, etc.) so having the absolute best AF precision would seem to be more critical.

EOS Bodies / Re: Patent: More DO Supertelephoto Lenses
« on: May 20, 2013, 12:51:27 PM »
I owned the 70-300 DO lens for a couple of years. While it wasn't a bad lens, the DO did take a bit of a toll on IQ, particularly in situations where lens flare was likely (strong light source striking the front element). Bokeh was a little awkward/choppy at times also. I understand that the 400/4 DO is a very good lens.

I'd like to see a refinement in the DO design that would produce an even better optical quality. The light weight and relatively small package makes a strong selling point for this technology.

The Kenko locks up the 5DIII when used with the latest generation telephotos, and you have to remove the battery to restart.

I found this to be true ONLY when AFMA is enabled. Otherwise, Kenko TC's autofocus fine at f/8 and did so prior to the 5D3 firmware update.

Agreed - I had that issue prior to the new firmware also. Could not micro-adjust the Kenko-lens combination because the camera would lock up. The solution was to delete the MA setting for that lens and not use AFMA with my Kenko (which I only used for F/8 AF situations anyway).

Further to what Doug stated, it's always been possible to 'trick' Canon's f/5.6 AF points into focusing with an f/8 max aperture, with pin taping or a TC that doesn't properly report.  Canon did not allow the functionality because it wasn't completely reliable.  Their recent firmware, possible coupled with higher density line sensors on the 1D X/5DIII (which is how the past 1-series bodies achieved f/8 AF), allowed them to enable it with confidence.

For the record, utilizing stacked teleconverters or third-party telecons (like the Kenko), I have been able to reliably autofocus with great results on the 5D3 (center region AF points), fair results (center point only) on the 5D2 and 5D, and "hit-and-miss" with the 7D.

Basically, the results I got with the 5D3 were so good that I was surprised that Canon hadn't included f/8 AF on that body right from the start. Perhaps they needed to iron out some issues first, I don't know.

I haven't given it a good full test yet, but I am enjoying backyard bird photography with the 5D3, 100-400 and the 1.4X II. Focus is reasonably quick, and it is pretty accurate. The image quality is decent, not on par with the big primes, but definitely not bad either. Occasionally, I find some weird pattern to the bokeh, but I think that's more a fault of the 100-400 than anything.

The true test will come with using some of the bigger glass and teleconverter combinations to see how it works for very long distance shooting. I've found, though, that stacking teleconverters does take its toll on IQ so that the results will be slightly less than optimal.

I'm really considering a 500/4 II in the future - somewhat light, and compatible with the 1.4X or the 2X teleconverters to give a variety of very long lens capability without the heft of the 400/2.8.
