EOS-M / Re: Poll: Would you have bought the M3? (North America)
« on: February 09, 2015, 07:06:50 PM »
Not the M3, I've got the A6000 now sharing lenses with the A7R.  Great travel combo....the canon is still in use for birding since there are no long lenses for E mount.  If canon steps up to match what the A6000 can do then I would consider it but the more I use the A6000 the more I like it.

The M3 feels like it is at about the level of the panasonic GF1 (which was excellent when it came out) in terms of usability.....hopefully a couple more generations and it will get there. 

EOS Bodies / Re: Sony Sensors Coming to Canon DSLRs? [CR1]

This I would love to see, doesn't stop canon from continuing to produce other sensors but this might give them a quick way to put out a high resolution camera while they continue to design their own for a next generation camera.

As a guy who is keeping his feet in both camps right now I am very happy to see sony advancing technology as quickly as they are.  Before this Nikon and Canon had been acting like Intel had been in years past.  Only adding tiny improvements to milk as much out of us as possible.  AMD caught Intel at that game for a couple of years, and sony is now doing it to Canon.  Intel took a bit of a beating but came back even stronger....and we will see what happens in this game. 

For me this competition means that technology isn't sitting in a lab waiting to be brought out in a few years, but is starting to hit different cameras now.  I love using my canon gear and continue to do so, but in the last six months I have been taking out the sony A6000 and the A7R more often due to size and weight and I can get the shots I want with either setup.  Who knows what I'll be using next year but I will still be having just as much fun.


Lenses / Re: Introducing the Canon EF 100-400 f/4.5-5.6L IS II

can't wait to see a comparison between this and the other new telephoto zooms.  I sold my 100-400 about a year ago after 8 years of birding and nature work.  I replaced it with the sigma 120-300 f2.8 for the low light with owls but this lens is definitely not a good travel lens. 

Looks like we are going to have interesting choices for the $1000-2200 range for long lenses all with attributes that will be good for some, and other attributes that different people will want.  If this new lens doesn't lose too much with teleconverters it is going to be hard to beat with its size....assuming it is on par with the 70-300L which was much sharper than my 100-400.

Because there is no need to. I enjoy using the canon gear along side the sony gear.  Canon is better at some things and sony at others.  The one area that canon is much better is very long lenses (300-800) and focus tracking, although now that I have gotten used to it the sony a6000 with the mid range zoom (70-200) is giving me better results than the 1D IV and the 70-300L or the sigma 120-300.  If a fast and long zoom comes out that is compatible with the on chip auto focus of the a6000 it will become a more difficult to choose which one I would carry around more.

I own the previous version of the sigma 120-300 and while it is an excellent lens, very sharp for a zoom lens and can handle the teleconverters reasonably well I would definitely go for the canon 300 if the cost was anywhere near close.  Unless you really need the zoom, the prime would be my choice.

Lenses / Re: Wildlife lens setup
« on: September 19, 2014, 08:00:24 PM »
Right now my setup is normally the canon 1D IV with the sigma 120-300 and often one of the teleconverters for the longer stuff and I keep the Sony A6000 with the 70-200 for the shorter reach stuff.  I can't wait to see the new sigma 150-600 sport to see how it compares to my current setup especially weight wise.

Funny how over the last couple of years I have pretty much replaced all my canon L lenses with sigma or tamron, (and lately with sony camera/lens options) with the exception of the 100L.  5 years before that there was almost nothing to compete with canon L. 

Lenses / Re: What telephotos do we own?

I used to own the canon 100-400L, used it for about 80 percent of my shots for about 6 years and fell out of love with it last year when I tried the Sigma 120-300 f2.8.  This has been my go to lens now for the last year using both the 1.4 and 2X teleconverters.  Great combo ( but rather heavy ).  I am looking at one of the 150-600 options for travel since my current combo is rather heavy unless I can get something for my sony a6000 that is long enough to make that my travel companion.

I've pretty much given up on canon coming out with something new in this range that I don't have to sell my car to get :)

I have been using the Sigma lens for the last 10 months or so, replacing my canon 100-400L as my main nature photography lens.  I mainly use this lens on my 1D IV with a few shots here and there on the 5D III.

Good things:
This lens is very sharp, my version has fantastic centre sharpness even at f2.8.
I can use both 1.4 and 2.0 teleconverters easily still getting sharper images than my old 100-400L (definitely not as sharp as the latest canon 300L with or without the teleconverters).
Autofocus is slower than any canon L series lens and almost nothing compares to the canon 300L, but tracking autofocus on the 1D IV even with a 2X teleconverter for birds in flight is still very good.  If the lens does lose focus it can hunt (I think this is better on the latest version with focus limiter).
Autofocus on my version is spot on for single shot.
IS works very well, especially with the teleconverters on.

Not so good things:
The weight is very significant for hand holding.  I have gotten used to it but the 300L is much easier to handle.
Weight and size are not so good for travel, I do considerable treks into mountains, woods, where ever and my neck and back pay for it.
No weather resistant properties is also a down side, but I knew that when I got it.

From my point of view this lens is more useful most of the time than my old 100-400L, and is pretty much in between the price points of that and the 300L.  I think it is more useful than the Sigma 300 prime at nearly the same price.  Nothing I have seen beats the Canon 300L in sharpness, autofocus speed, and most of the other features, but I was able to pick up the Sigma used for $2100.  That extra $3-4000 for the Canon is still difficult for me to justify, at least until I can make enough off of my nature shots or hit the lottery (likely both about the same odds :) )

I may change my tune if/when canon updates their telephoto zoom.

Here is one of my latest shots tracking a Black-crowned night heron using 1D IV, Sigma 120-300, canon 2X teleconverter.

Love shooting Owls - here's a few of my favourites.  Most of these have been shot with Canon 5d II, Canon 1D IV or Canon 5D III and either Canon 100-400L or Sigma 120-300 f2.8 (and 2x teleconverter).

Sounds like the options here are 1. extremely expensive and 2. Very inexpensive.  I've gone in between with the Sigma 120-300 f2.8 and canon version III teleconverters.  I'm very happy with the image quality so far comparing mostly to my old canon 100-400 and newer 70-300L.  The extra stop or so of light is great but the weight is significant.  Anyone else have the sigma and access to the tamron for comparisons?  I already know that the canon primes are slightly sharper and significantly faster for autofocus.

I've been considering the tamron for those times that I don't want to/can't take the heavy weights.

Now a couple of Icescape type shots (I would call them landscape but there really isn't anything but ice up here right now)

AWESOME! ... What lens did you for these?
Thanks, first one is with the canon 40mm f2.8 and the second is the Tamron 24-70 f2.8 at 24mm (canon mount).

Couple of recent shots both taken with Canon 1D Mark IV, canon 2x teleconverter vIII, and Sigma 120-300 f2.8

Snowy owl taken is harsh light, typically cloudy day.
