Looking at the corner crops at f11' one can see some elongation of the specular highlights in the snow (coma). No wings though. Is coma the same at f2.8? Thanks for the preview!

Take a look at the new video and judge for yourself.  I haven't been able to shoot at night yet, unfortunately, because it has been snowing here pretty much non-stop and there hasn't been any clear skies. I will be posting a new article somewhere in the next 24 hours with a lot more crops from another series along with comparisons to other lenses.

If I get a look at the night sky (I only have two more nights with the lens before it moves on to another reviewer, unfortunately), I will definitely be looking at coma.  I was just written to by another photographer who has the lens in hand and he stated that the lens is awesome at night.  Low coma and very crisp points of light.  My new resolution comparison with the Rokinon 14mm f/2.8 (my current astraphotography lens) makes me think that he's probably right.   http://bit.ly/1Aac03H

Hi everyone, I did a controlled series yesterday where I took a ton of shots at all major apertures (f/2.8-f/11) on three lenses (ones that I had on hand):  the new Tamron SP 15-30 VC, the Samyang/Rokinon 14mm f/2.8, and Tamron's own 24-70 VC.  I have also recently reviewed both the Canon 16-35 f/4L and the Zeiss 15mm f/2.8, so those lenses are also fresh in mind, but I didn't have a copy on hand for a direct comparison here. 

I think you will find the results interesting.

P.S.  Can anyone tell me how to directly embed YouTube video here?

I've got a new video where I interactively look closely at the resolution at major apertures (f/2.8, 4, 5.6, 8, and 11) in a direct comparison between the new Tamron, the Samyang/Rokinon 14mm f/2.8, and the Tamron 24-70mm f/2.8 VC on the wide end.  The results are pretty amazing.

Thanks for your insight Dustin, love your reviews! I myself is very satisfied with Tamron SP lineup lately. If I haven't recently bought my 16-35 F4, I would have definitely went for this one.

The 16-35 f/4L IS is a great lens.  I held off because I knew this lens was coming and I wanted to test it first.  Having use a number of wide angle options in the past six months (Zeiss 15, Rokinon 12mm (mirrorless), Canon 16-35L, Samyang 24mm T/S and now this Tamron, I can safely say this Tamron is my new pick for a w/a option.  Literally the only thing that I can find wrong with it is the fact that it is large (and it is really big!) and doesn't take traditional filters.  I've not minded using square filters with my Samyang/Rokinon 14mm, so I can handle that with this lens.

Great review - the only problem was it was so enthusiastic I started to wonder whether a lens really could be that good!

I gave up reading for the annoying facebook, twitter, google+ and linkedin redirects down the left side of the page where the text is, insecure much?

I thought they were in a pretty annoying place too, reading on a tablet, until I realised that in portrait orientation they move to the bottom right - or disappear altogether depending which browser I'm using. Out of curiosity I just looked at the page on my desktop PC, and they are there on the left but the left margin is much bigger (despite the resolution being identical to my tablet at 1920x1200) and this makes it ok. Responsive web design is great, but they don't always get it right!

Thanks to everyone for the feedback on this issue.  I've passed it on to my web developer.  I don't have an issue on my devices, so it's good to know there is one from others.  We'll have to work on the positioning of that widget.

I get a lot of feedback about the importance of social media sharing from my partners, but it is all a work in progress for me.  I'm a writer and a photographer, but web developer, not so much.

Very nice thanks for sharing. Whoa 40 below that's insane! Sounds like that VC might come in handy for handheld :P

That is definitely true.  The lens seemed to perform fine in the extreme cold, though...so that's a positive.

40 below - you're crazy!!!  Thanks for sharing this, and it looks like Tamron continues to really step up their game.  Those crops at f/11 look really good for a lens this wide.  How does it compare to the quality wide open?

I'll attach a good size wide open image here for people to pixel peep.  Another that I took in the crazy cold this morning.  This was shot in RAW, but has been converted with a Lightroom sharpness setting of 60 at 1 pixel width.  You can see there is some vignetting, but it's actually not bad (wait until you see it compared to my Rokinon 14mm f/2.8 - now THERE is some vignetting!).  Depth of field is smaller, obviously, but resolution is still excellent.

I did an in depth breakdown of the image quality from the new Tamron SP 15-30mm f/2.8 VC lens with a number of crops and examination of what it all means.

I don't think that I am letting the cat out of the bag by saying that this is a very compelling lens.  My full review is yet to come, but for those of you looking for some early info, take a look at the article here:  http://bit.ly/1E5uvqD

P.S.  Here is a photo of me taken with the lens this morning as the sun rose out on a frozen river.  It was about 40 below...and my trigger finger is still a bit numb 5 hours later!

Thanks for the nice feedback everyone, and to CR for being a great partner in sharing my reviews.  Roger's breakdown makes me even more enthusiastic about this lens.

This is awesome to read. I've updated my review with this information and linkage to the article.  Roger's work is invaluable because, unlike we lens reviewers, he has intimate knowledge of what works in internal construction.  The photography world is a better place because of him  :)

Nice shot, LovePhoto! The 600 is great for the moon.


It's also great for other space stuff. Orion's Sword:





Canon EOS 5D III
Canon EF 600mm f/4 L II
Orion Atlas EQ-G (Rowan Belt Mod)
Really, really dark skies
Over 2h 20m total exposure time



That is amazing!  Very cool capture!

Reviews / Senal SMH-1000 Studio Monitor Headphones Review (Dustin Abbott)

Hi, everyone, if you are looking for a great set of studio/field monitor headphones (or just a great set of general purpose headphones), this relatively unknown brand has made a pretty fantastic pair.  I got some for myself after reviewing them because the sound is great (very neutral) and there is a lot of great little features.

Some great shots.  I love shooting with vintage glass.  My most recent toy is a vintage Zeiss Planar T* 1.7/50mm.  Really quite a beautiful lens, and very sharp when you nail focus.

The Makro-Planar 50 is a sweet lens!  Here's a selfie I took with it (holding the Otus 85 - sweeter still!)
