I've got it in hand right now.  It is a beast.  I intend to AFMA it before giving any kind of report on the IQ.  I am also clearing just what kind of information I can share right now.  There is a moratorium on reviews, but I probably will able to share some bits and pieces.

Here's another taken (wide open) with the 35mm f/2 IS. 



To see how I turned a fairly basic snapshot into this, take a look at this tutorial:

My copy for review was shipped today.  I should have it by Wednesday.  There is moratorium on full reviews, and the first dibs on mine will be going to PhotoNews, but by the end of the month I should be able to share the full review. 

My contact at Tamron seems more pumped about this lens than any I've heard him mention before.  He said this to me:  "Our internal tests are showing the lens provides very sharp photos and every one - so far! - is very pleased with its performance."

I'm excited to get my hands on it!

Hello, everyone!

Here is a new workflow article for those interested in my process.  This demonstrates how that I use Snap Art 4 to help create the formal portrait out of the snapshot.

As a bonus, I have 10% discount coupon for anything from Alien Skin in the article.  Thanks for your interest.

Not sure if this is the right thread for this...

Here is my 1st attempt at star trails. The composition is not so good since my prime objective was to first get the star trails. Shot with Canon 6D, Samyang 14mm UWA lens @ ISO1600, F/4, 20s for combined 93 shots, stacked with StarStaX. Actually had to delete ~60 shots because I did not notice the lens was frosted up.  Outside temperature was approx. -1C near Daejeon, South Korea.

I pre-focused (Jupiter) in live view to achieve sharpest focus.  Surprisingly at F/4.0, the sharpest focus is set at the 'infinity' mark (hard stop) which is different than what I saw on my previous tests.  At F/2.8, I could not get sharpest focus because I would have to move the focus ring beyond infinity and this is of course not physically possible.

Open questions:
1) How could I prevent frost from forming on the lens during cold winter nights?
2) How can I get sharpest focus now at F/2.8?  Should I even consider shooting at F/2.8 anymore if F/4 is ok?

First of all, nice job.  I'm surprised at your conclusion regarding infinity focus.  I have mostly heard of people hitting infinity focus before the hard stop and having an issue with the lens focusing beyond infinity.  I would say that for your star trails shot that shooting at f/4 is your best option.

I don't know how to solve your frost problem, unfortunately.

I read your review with great interest... (good review!)

I still have my "adaptall" 90mm Tamron macro lens.... back in the days of film it was the best lens that Tamron ever designed. It is still a fine lens (but completely manual) on my 60D, but I ended up getting the 100L for it's improved image quality and IS.

To say that a 40 year old lens is "a fine lens" speaks very well for it.... I would expect an improved version of the lens, like the one you tested, to be a very fine lens. Here's hoping that the Tamrons and Sigmas of the world put out more quality lenses at affordable prices...

Thanks for the good feedback, Don.  Your final statement really mirrors how I feel.  My current kit (the modern version - I have a vintage kit, too) is dominated by Canon glass (5 lenses).  I also own one Tamron and one Rokinon.  But here's the thing:  that Tamron replaced the 24-105L and the Rokinon replaced the 17-40L, and I have been very happy after time that I made that decision.  That's great news to me.  I think that it means that new lenses by Canon will be even better with more pressure.

How much better will the 35mm f/1.4LII be because of the S35?

I too own the 100L and it will be a long time before I part with it, but I still like the fact that this very competitive alternative exists at a lower price point.

Beautiful shot. I like the sky colors reflecting on the ice surface. Nicely done Sir.

Thanks a lot, Click.  I too like the cool/warm color graduation on the ice from the rising sun.

Here's the lens used as a medium telephoto in a landscape application.  Very nice detail and color rendering.

Canon EF Zoom Lenses / Re: Canon EF 70-300 f/4-5.6L IS USM

Taken long after the sun had gone down, the mist rising from the river and meadows was filling the Stour Valley. The river can just be seen in the left of the picture, and the steeple of Dedham church is just right of centre.

Shot with the 6D and 70-300L @125 mil, ISO 1600, f5.6, 1/50th. A six frame hand held panoramic.

Lovely color palettes.  I find the color rendering out of the 70-300L to be excellent!

Here's an example of a handheld macro with the Tamron.  I find that it is pretty similar in practice to shooting like this with my Canon 100L.  Tamron's VC systems are very, very good.

P.S.  Here is an untouched/unedited ring shot from the 100L.  From this distance you could literally shoot at 1/10th and not worry about the outcome.  This is f/4.5 to allow enough depth of field for both hands to be in focus.

  Still, above all it is the results that matter to me.

Thanks Dustin.

You're quite right; it is the results that matter. It's just irritating that for someone who cannot afford, or doesn't wish to afford the 5D mkiii, the choice is a 6D or used 5D mkii. The 6D is the better camera, it has the edge on the 5D mkii even at 100 ISO in certain (difficult) lighting conditions, but you then have to accept the more Rebel orientated controls.

Full marks to Canon for differentiating between the 6 and 5D lines  ;).   ::)

I'm afraid that the emoticons are right on.  Those of us who own the 6D know that it is an amazing camera, and yet still the blatant crippling of it in certain areas does rankle.  A combination of the feature set/design of the new 70D with the 6D would be pretty much an ideal camera for me.

First of all, I do shoot weddings, own the 100L, and love it.  It will be in my kit for a long, long time.  If money is an issue, however, I have just spent some time with the new Tamron 90mm Macro VC lens to review it, and it is a very, very competitive option.  Here's my thorough review of it if you want to check it out:

http://www.dustinabbott.net/2013/12/tamron-sp-90mm-f2-8-di-macro-11-vc-usd-review/

It offers basically everything that the 100L does (slightly worse bokeh, slightly sharper optics) at a price point that falls between the EF 100 Macro and the 100L.

Lenses / Re: DXOMark: Sigma 24-105 f/4 DG OS Reviewed
« on: January 01, 2014, 11:12:26 AM »
After shooting over 500 images with my new S 24-105 I am much more pleased with the wide end than I ever was with either of my 2 Canon copies. The OS and AF are great without any discernible difference to the Canon counterpart. It weighs a TON but I'm used to lugging a Tamron 24-70 around so it's ok for me on a 5D3. I was able to shoot down 4 stops at the long end without issues and it controls flare somewhat better than the Canon. Bokeh is oniony but it's no Sigma 35.

Worth $854 anyday imho. (B&H EDU price)

That is a very handsome image.
