I don't really know what to make with this, but it does not at all equate to what I am seeing.

I won't elaborate further other to say that I have yet to see a Tamron lens "chart" particularly well at TDP.

I've thoroughly tested both lenses, and they are both great, but my personal preorder is in for the Tamron.

Post Processing / Processing Workflow Tutorial for Alien Skin Software
« on: February 17, 2015, 11:38:13 AM »
Hi everyone, I just did a new video tutorial article for Alien Skin software using a shot from the Canon 100-400L II + 1.4x teleconverter.  I used Exposure and Snap Art to take a simple high key shot of a horse into a painterly, classic finish.

Take look if you are interested:  http://www.alienskin.com/dustin-abbotts-horse-portrait/

Here's a wide open one for you to peep at a bit here.  I've processed it a bit to help the stars pop (and to try to deal with the light pollution everywhere), so at a pixel level there is some extra noise, but it will also make it very easy to check for coma and determine whether it is acceptable for your purposes.

I'm working on the final review right now.  The video review is already done and uploaded, but it is still unlisted until I am ready to go live with everything else.

Canon 6D, EF 70-200mm f/2.8L USM, 1/1600 sec;   f/4.5;   ISO 800

some LR CC, PS CC oil paint

That's quite a lovely result.  I really like it.  The colors are fab!

The discussion about coma is on another thread, but I thought I would share here that I finally got some reasonably clear skies and was able to shoot about five nightscape shots (it was -20F, so I didn't linger!).  I am very satisfied with the result from the lens for this kind of shooting.

I went into my catalog and compared some nightscapes from the Rokinon and the 16-35 f/4.  The Tamron has less distortion towards the edges, and that caused more stretching on the Rokinon.  The performance from that Tamron is good enough that I feel I could let the Rokinon go in favor of the Tamron and not lose anything.

The 16-35 f/4L was simply not as good for astraphotography, in my opinion. I never got the starpoints to render as sharply, and, of course, you have only half the available light to work with.

One big plus is that the focus window is accurate on the Tamron.  I just put it on infinity before going out to shoot and got a very sharp result.

Finally got a peak at the sky last night.  So cold, though, that I didn't linger too long and wasn't in the best of conditions.  Still, I'm pretty impressed with the low coma and the very nice performance for a night sky shot.  I've processed this to make up for the light pollution and allow the stars to shine, but I would say this lens is probably doing as well as the Rokinon other than not having as dramatically wide a field of view.

I've got a few more that I will share shortly.  The specs:  ISO 1600, f/3.2, 15 seconds.  The aperture wasn't to add sharpness so much as trying to get the exposure I wanted.

Can someone ban Dustin from this site please?

I was doing so well telling myself I didn't absolutely need this lens until that excellent review  :D

LOL.  Just call me a troll and ignore me ;)

The problem should be solved now.  The "Share" buttons have been moved to the right side where there should be the buffer of the side links to prevent a similar problem.  If any of you that have had a problem would be kind enough to let me know if this solves the problem for you, I would be obliged!

Wow!  40 below - was that degrees C or F?  (Oh wait, it doesn't matter!)  It's only -7F here today with wind chill around -25F.  I probably won't be out shooting.  In film days I used to do shots like that often; but, now I prefer to follow the manufacturer's recommendation on camera operating temperatures - I stay warmer that way.  Any issues with your 6D at those temperatures?

Great Sunday morning inspiration however.  And, the lens looks interesting as well.  Looking forward to full review.  Thanks.

My 6D has never balked at me in any kind of weather conditions.  It really is an excellent camera.

Very nice comparison video.
I must say that I am just a little bit shocked about the quality difference between the 24-70VC and the 15-30. Makes the 24-70 look poor in IQ. I had it compared with the 24-70II of Canon and the difference between those two was not so big as here between 24-70VC and 15-30VC. I love to see the comparison between the tamron 15-30 and the canon 16-35 f/4 IS

Well, my copy of the Tamron has obviously gotten decentered (I've taken it to countries all over the place and I'm sure it's gotten knocked around a bit).  I'll send it to my buddies at Tamron here in Canada and get that looked after.

Still, I know the Tamron 24-70 VC to be a very competent lens, so that the fact that this new lens leaves it in the dust bodes very well for it.

I only have the 15-30 VC for another day or so, so a direct comparison like this is out of the question for now.  I do plan on purchasing the 15-30 VC for myself, though (although I'm not sure how long it will take for me to get one), and I will have B&H send me a review copy of 16-35L to do a direct comparison with.

This one shows off how nice the bokeh rendering is if you get close to your subject.  It's surprisingly good.

Soft and Sharp - Tamron SP 15-30mm f/2.8 VC by Thousand Word Images by Dustin Abbott, on Flickr

This is a huge lens, but l am drawing the conclusion that Tamron essentially did what Zeiss did with the Otus line and told the engineers, "Forget about making it small and light.  Just make it awesome."  Unlike Zeiss, though, they also said, "Make the price reasonable".

Here's a couple of other images that I've shared from the lens so far - I've managed to a get number of great shots despite weather that has been pretty brutal over the brief time I get to have the lens.

Here's a three image panorama that I took while doing this resolution test.  The original is pretty amazing.
