Not much of a shot but here's the twist.  It was shot using the 6D wifi from my computer in warmth while it's -20 C on the deck! ;)

However, I'm not too thrilled as I've been having problems keeping the connection and can't get it back.  Anyone have experience with this 6D wifi and know the typical pitfalls?  The EOS utility and live view shooting seems very clunky and I was getting pretty frustrated with the slowness of focus and the time transfering files to the computer etc.  Seems a mixed bag.

Jack, I'm afraid that is pretty much par for the course.  I have managed to get it work fairly well for some applications, but the refresh rate on your screen is slow, as is focus.  I suspect the focus probably works better with the 70D because of the DPAF and thus faster live view focus.  I don't know that the cold is the factor, though, as I have shot from my car for LE work with it close to -40 outside.

P.S.  I think the Snowy Owl shot is great.  Wish I had taken it.  I'm not a huge bird guy, but I really like owls.

For all of you birders, here is a pretty amazing review of the lens by a guy comparing it to the 600mm f/4L IS (original version):

The comparison images of the Red-Tailed Hawk have the bird occupying half the height of the frame. At that size, the image should be extremely sharp with fine details of the plumage visible. You can see that the head of the hawk from the Tamron is soft. All of the images I have seen at 600mm f/6.3 are soft to varying degrees, as you would expect from the measured MTF charts published by different reviewers. However, the lens gets significantly sharper at f/8-f/11 and the lens should be very sharp. So would someone please post some shots at f/8-f/11 so we can see what the lens is really capable of doing. How about it Don?


Alan, I get what you are saying, but as Roger rightly pointed out in his comparison, it is the lighting and conditions that are going to make the biggest difference.  I know what you want to see, but for many of us that have had the chance to use the lens, we simply don't have the kind of lighting conditions that are going to produce the most optimum photos.  It's January, not exactly a month cherished by photographers around the world.

The takeaway for me is that here the lens was compared to a high end 600mm and wasn't trounced and that he got a great shot tracking with the lens.

Here's another shot from me:

Here's a fun shot that I've have post processed to give a faded look, but does give an idea of what a 150mm shot at f/8 might look like through the lens.

Hey fellas, what's going on? Jack Douglas is using the same bird at the size in the thread about the 300mm f/2.8 II with stacked 1.4 and 2xTCs

http://www.canonrumors.com/forum/index.php?topic=19248.30

Jack's photo is at iso 4000, and he complains that he is not impressed with the results. Download Jack's and Don's image and compare. To my eyes, the stacked TCs have given a significantly sharper image. But, the conditions are different. I have uploaded Jack's here (apologies Jack).

The handheld 60D photo looks pretty damned good to me.  By 60D standards, of course.  Pitting the results of a 60D and a 6D is hardly a fair comparison, though.

Based on TDPs image comparison tools -- since I don't have a 6D to compare to my 60D -- I'd say that the results are at least equivocal.  Certainly the 150-600 is more versatile, less cumbersome, and less convoluted than stacked teleconverters and a prime.


I am not arguing in favour of using stacked TCs - I am sure the 300/2.8 II plus the 2xTC at 600mm would give better results cropped than the stacked. Don't you think it amazing that two different threads on different subjects used a crop of the same bird at almost the exact same size?


I'm actually not surprised, as this is one of the few birds that I see with any kind of regularity in a Canadian winter.

5DMiii + 100-400L


That's nicely done.  Love the muted colors in the backdrop here - very rich.

P.S.  Note how narrow the DOF is on the goose shot when you consider this was 600mm, f/7.1, and I was about 25-30 feet away (roughly).  The breast and the face is in focus where it is one the same plane, but the wings are very much out of the plane of focus.  You can still get good separation even with this more narrow aperture zoom.

85
Here's a couple of more shots:


King of the Road by Thousand Word Images by Dustin Abbott, on Flickr

This last one is a near wide open (f/7.1 - 1/3rd stop stop down) and 600mm shot using AF Servo (not the 6D's strongest suit) but it worked fine for my limited bird use.  BTW, the squirrel shot on the last page was also using AF Servo, but he had stopped moving by the time I took the shot anyway, so I don't think it would be any different than using One Shot.

I can't speak for everyone, but I own multiple teleconverters and frankly I kind of hate using them.  In the field or at an event, I often don't bother with changing it out because of the environment, the amount of time for the switch, or the risk of getting gunk in my body during the change.  The 135L takes a 1.4x quite well, and I do use that combination, but let's be realistic; it is only 189mm, and an unstabilized 189mm at that.

The 70-200L II takes teles very well well, too, but even on it with a 2x there is quite a degrading of image quality, and it is a 400mm f/5.6 by that point.

If you want reach, the Tamron is the best bargain option on the market.  I'll certainly be adding one to my kit.  And for those saying it is only good up to 400mm - they haven't used it.  I thought I was taking this wide open, but it is actually f/7.1 (stopped down 1/3rd a stop).  But it is 600mm, handheld, and ISO 2000.  How exactly is this not usable?

Third Party Manufacturers / Re: Review: Sony A7R With Canon Glass
« on: January 28, 2014, 05:33:59 PM »
Those are very compelling images.  It doesn't sound like dealing with adapters is ideal, yet, but the A7R sounds like a great platform for using vintage glass! 

I have to say again, though - those are some great looking landscapes, and the shadow recovery section is also very impressive.

Excellent review.

I am definitely putting this lens on my shopping list.  An extra 200mm over the 100-400 is just what I could use for bird photography.

That extra 200mm certainly makes a difference.  I haven't really shot the lens on a crop much (other than the M ::)), but the reach on a 70D/7D would be amazing.

...

So what was your experience with the Tamron on the EOS M?

It's mostly about logistics.  The M is so small that the balance is really weird, as is trying to operate the camera with such a small grip.  It would be better on a monopod or tripod, obviously.  As this pictures shows, it is very much a case of the "tail wagging the dog"  ;D

Is that a camera, or a rear lens cap on there?  :P

Exactly.  Pictures look fine, but logistics are pretty brutal.

Tamron 24-70 VC  I love listening to people on this forum bash this lens while I take it around the world and make photos like this with it :)

I hate all 24-70 lenses regardless of brand. I am an equal opportunity 24-70 basher. =P

Consistency is good  ;D
