Third Party Manufacturers / Re: 150-600mm Sample Images

These are the sample images from Tamron's site.

http://www.tamron.com.hk/A011/

I thought this one looked very good for a 600mm zoom.  Certainly much better than 400mm + TC.

Just brought that image (TIF) into Lightroom and looked at it @ 100%.  It is stopped down a stop from wide open (f/9), but even so it looks pretty sharp.  Individual hairs are resolved quite well.  Even better, the transition zone looks good (and that was a real weakness for their 70-300 VC).

...even full size images are supposed to look very good according to my contact in the company.

They're going to send you a preproduction copy to review, they know you're going to publish that review, and a company rep tells you the images look very good.  Amazing...   ::)

While I understand your skepticism, if you have read my reviews you should know that I attempt to be completely frank about lens' weaknesses as well as strengths.  There has never been any attempt to bias my results, and, since my primary occupation is as a pastor, I do value honesty.  ;)

For $1100, it wouldn't surprise me if an image cropped from the current Canon 100-400L at 400mm gives IQ that's at least as good as the Tamron at 600mm.

I haven't gotten my hands on the pre-release copy yet (hopefully over the next few weeks), but even full size images are supposed to look very good according to my contact in the company.  I'm skeptical at your statement.  The 100-400L is hardly a new design.  I wouldn't be surprised if this were true of a redesign of the 100-400LII, but not the older one (of which there is huge sample variation anyway).

The Sigma 150-500mm DG OS HSM APO is 10 years newer than the 100-400L, and in the same price range as the new Tamron (a little cheaper, but 100mm shorter). The cropped 100-400L is optically superior, as is the 100-400L + 1.4x TC (and the lens takes a big IQ hit from the TC).  So, I'm skeptical of your skepticism.   ;)

Also, since Tamron is sending you a copy, I'm frankly skeptical that your tests will be representative of production lenses (nothing against your testing, but I don't put much faith in reviews where the lens isn't purchased through a normal retail channel).

Fair enough.  Tell you what, if you hear/read that I am buying the lens for myself, that should send a pretty clear signal 8)

I want to see what happens when Roger from Lens Rentals runs a dozen through his test bench. Evaluation based on a single copy, although interesting, is inherently flawed as it is statistically insignificant, particularly when that single lens may or may not have been specially selected.

Also, when you look at the published MTF curves, it seems to indicate a soft lens once you get away from the center when it is zoomed out.....

We will likely find out later in January as I am sure Roger will have a few on order.

That is always one of the most important benchmarks for me, too.  It gives you a better sense of your "odds" in the sample variation lottery.

Wow.  The concept is cool, but how many people in the world are going to buy a two thousand dollar lens to mount on >$300 camera?

1/15th second @ 70mm = no hesitation.  Just part of the reason why the Tamron is just a great travel lens.  And that bokeh ain't bad, either :)

Here's another - this one from the souq in Old City Jerusalem.  The Tamron is a great travel choice, in part because I can shoot shots like this @70mm and 1/15th shutter speed without even worrying for a moment about sharpness.

I wonder if the SP 2X Pro Teleconverter would work with this lens?

But on what body would it AF?  You already have a max aperture of f/6.3 on the long end.  I wouldn't be surprised if my Kenko 1.4x works, though.

That really is an amazing focal length.  If the lens quality is up to Tamron's recent standards, I think this will be a great seller for Tamron.

EOS Bodies - For Stills / Re: The Unthinkable: Swapped out 5D3 for 6D
« on: December 13, 2013, 10:23:48 AM »
Had a 5D Mark III for most of this year, but had to sell it for some unforseen medical expenses.  I've been using my old T3i for some time, but greatly missed the full frame.  With all the holiday sales going on, I bought a 6D with a 24-70 mark ii.  It will be in on Monday, so I'll be interested in seeing how much of the features from the 5D I'll miss.  Will post an update soon :)

Just depends on what you shoot and what your habits are. My hunch is that you'll probably be quite pleased if you are okay with the AF system difference (which using the rebel for a while should soften the shock of  ;D).

I'm thinking so.  I mainly shoot family portraits and photos of my family.  I just hope I didn't spoil myself with that 5D autofocus.  If I miss it terribly, I'm sure I'll upgrade one day.  But I was able to get the new 24-70 with the price difference in bodies.

Gulp!  Wow!  That is pretty huge.  I should pause and ask, "which new 24-70"?  The f/4L IS, I say, "nice".  If you are talking the 24-70LII, that is a big "Wow!"

6D Sample Images / Re: Anything shot with a 6D
« on: December 13, 2013, 09:15:01 AM »
This is a framegrab from video. I was a little hesitant that the 6d couldn't achieve that magic look like my 5D ii but it assurd me that the 6d is very capable.

Truthfully, I personally feel that the video thing has been overblown about the 6D.  I have been very pleased with the video I have personally gotten from the 6D, and it is SO much better implemented than on the 5DII I used previously.  I have seen great video from other people as well.  Moire is an issue, but I have personally only seen it one time in my personal use.

Tamron 150-600mm will release in Japan for the Canon mount first on Dec 19th. We should start seeing some reviews soon. And pricing in Japan has been set at 140,000 yen ($1350 US). :)

http://www.tamron.co.jp/news/release_2013/1213.html

They have also created a new site just for this lens.

http://www.tamron.co.jp/en/lineup/a011/index.html

Also just release versions of Camera RAW and LR contained lens profile for the Tamron 150-600mm.


That is great news.  I was unaware that the Japanese release date was so soon.  That is a very attractive price, too.  Thanks for the info!

Canon EF Zoom Lenses / Re: Canon EF 70-300 f/4-5.6L IS USM
« on: December 13, 2013, 09:09:23 AM »
Love the image of the burro or donkey.  Was it natural light or did you build the shot?

That is shot only in natural light, very dim, so I shot ISO 6400 (which on a 6D is still amazingly clean).  Shutter speed was 1/50th.  I previously had the Tamron 70-300 VC before the 70-300L, and the one area where the Tamron has the Canon beat is in the image stabilization.  I am actually disappointed in the 70-300L in that regard.  I find that I need to be really conscious of using proper technique at lower shutter speeds, otherwise I end up disappointed.  This shot, however, looks great at full magnification.  That being said, it is also only 120mm, so its not like hard core stabilization was needed. 

The Canon blows the Tamron away in bokeh, however, and sharpness and color rendition are both better with the Canon.  The Tamron is a surprisingly strong performer considering its very low price point.
