Reviews / Tamron 16-300 VC Review and Video Review
« on: August 29, 2014, 10:55:05 AM »
Hello, all.  Just completed a review of the new crop sensor all-in-one lens from Tamron, the 16-300mm f/3.5-6.3 Di II VC PZD.  This lens has a massive 18.8x zoom range, and on a Canon crop has an 35mm equivalent 25.6-460mm range.  That is both wider and longer than all previous lenses of the type.  If you would like to read more about (or watch the video review), you can click here:

Tamron 16-300mm f/3.5-6.3 Di II VC PZD Review by Thousand Word Images by Dustin Abbott, on Flickr

P.S.  I have previously reviewed the 28-300 VC for full frame bodies, and B&H is currently sending me the 18-200 VC for EF-M mount that I will be reviewing (alongside the Samyang 12mm f/2 for EF-M and the 16-35mm f/4L IS).  Full plate for a bit, but the new reviews should start coming in about a month.  Somewhere in there Zeiss will be sending me the two Otus lenses for review (55 and 85mm).

Is there anything out there that hasn't been reviewed much that you guys want me to request in the future?  At this stage I can get just about anything for review (although some of the higher end superteles are a little more work to get).

That is really fab.  Nicely done!

I made a home-made solid ND filter for the system from a couple of mattes with a sheet of LEE ND film in between them.  Not perfect, but seems to work until I can find the real solid ND filter for the system.  I seem to get about three stops out of it and can use it in conjunction with the grad ND.  I've filed tested it a bit now and like what I'm getting.  For example:

darn, looks like a parasail of some kind.
why so big? Wonderpana system looks way more efficient and small - I have been looking at it, as it would fit both R/S/B 14mm and the Ts-e 17mm

Thanks for taking the time reviewing and posting it

The system is huge - no doubt about it.  Similar systems for the Nikon 12-24 are similar, though.  These lenses have such a huge angle of view...

The ability to use traditional filters is a big plus for the new Canon 16-35mm

It really is a huge setup but cool that it actually exists. Samyang keeps coming with an amazing array of products at an incredibly high rate.

Love your tie, by the way  8)

That's true.  I'm actually really happy to have it.  ND Grad filters are hugely effective for landscape work, and you basically don't get one without going to a square filter system - and they are always a bit clunky.  I've got the Cokin P system, and while it is smaller and cheaper, it isn't much different.

Thanks on the tie :)

I think I might get this lens as a take along/do it all canoe tripping and hiking lens on the 6d. Have you tried it on a crop camera? I wonder how it compares IQ wise compared to the 16-300? I know it has less range on the wide side but I would prefer it if the IQ is better on a crop body as well.

I haven't posted my review of the 16-300mm yet, but I actually make that case.  There are more optical compromises with the 16-300 and I still like the 28-300 better on a crop.  Less loss of resolution and contrast on the long end.  The biggest downside, of course, is that 28mm isn't particularly wide on a crop.

Here's a sample taken with the lens on a crop camera (300mm wide open).  Crop body is an EOS M in this case, but I did the review primarily on a 60D.

I recently did a review/video review of the filter system made by Samyang for the 14mm f/2.8 lens from Samyang, Rokinon, Bower, etc...

The system works well, although Samyang's distribution in North America is basically nonexistent.  I had to use Ebay to get mine even though I work with the Rokinon distributor in North America.  I still have been unable to get the solid ND filter, but the ND grad is a treat for it.

Anyway, here's a link if you are interested.  http://dustinabbott.net/2014/08/samyang-14mm-f2-8-filter-system-review/

I'd be interested in reading any of your own experiences with both getting and using the system.

Reviews / Quebec City and the new Tamron 28-300 VC as a Travel Lens
« on: August 18, 2014, 11:45:20 AM »
I recently did a review of the new Tamron 28-300mm f/3.5-6.3 Di VC PZD lens (someone posted a link here, but if you didn't see it you can find the review here:  http://dustinabbott.net/2014/08/tamron-28-300mm-f3-5-6-3-di-vc-pzd/).  It is an obvious choice for travel, but I hadn't actually traveled with the lens.  I just spent 4-5 days traveling to the beautiful Quebec City and used the Tamron almost exclusively.  This is a companion article with a lot of photos that show off the range and image quality of the lens in a variety of settings.  It is also a bit of a travelogue on Quebec City.

Enjoy.

I'm not crazy about f/6.3, either, but it is also 1/3rd of a stop of light.  It is rare that the 1/3rd stop makes much of a difference, and the high ISO performance of the 6D that I use it with means that I can get away with cranking ISO and still get very nice images.

I suspect that the 28-300L probably has higher resolution than this lens...but I doubt the difference is significant.  This lens is surprisingly competent (I wasn't nearly as impressed with the new 16-300 VC for crop).

Does f/6.3 affect AF performance when using off-center AF points?

It doesn't seem to on my 6D (and also on a 60D that I tested it on).  I think there is some kind of trickery that makes the camera "think" it is f/5.6, and it acts accordingly.  AF is actually very good on the lens, and seems accurate.  Other than rather slow apertures, the only downside I've discovered is that resolution/micro-contrast isn't as good as my best lenses at higher magnification, but that's hardly a shock.  I've been more surprised at how good the images actually are.

On the 6D, outdoors, using the center point, my 70-300L with a 1.4x extender has worked pretty much flawlessly for me even at the long end, where it is equivalent to f/8.  Experimentally, at f/12, it fails reliably, but almost works (gets the focus right, but doesn't acknowledge that it did) much of the time.  So I'd guess that the 6D's daylight focusing limit is somewhere just shy of f/12.  I wouldn't think f/6.5 would even be a challenge for it except in fairly bad lighting conditions unless you stick a TC on it.

Out of curiosity, what does the EXIF tagging show for the f-stop?  From what I've seen when working with MF lenses, I'm fairly certain the lens can't lie to the camera about its wide-open aperture, or else every shot would be underexposed by a stop.  But perhaps it could get around that by lying about every setting equally.  If that were the case, wide-open shots would claim to be f/5.6 at the long end, even though they really can't be.

First of all, the EXIF data is always correct.  But somehow third party lenses have had a workaround that bypassed the f/5.6 maximum aperture limitation for many years.  I understand that the trickery is not so much about metering as it by bypassing that limitation.  Magic Lantern software also can bypass that same limitation for all lenses, so it obviously more of a software limitation than it is a physical limitation.

JumboShrimp here. No connections to anyone or anything here. ;)

Thanks for sharing.  I assumed that somebody at CR had shared it.  They've shared my last 3 or 4 reviews themselves.

Thanks for the review Dustin, I've owned both the 28=350mm L and the 28-300mm L IS.  They are wonderful lenses, but heavy and the aperture only makes them suitable for at least moderately good light.

I do wonder about the even smaller aperture of this lens.

I think its great to see so many affordable new FF lenses that are ever improving in quality.  This will allow more and more photographers to move from crop cameras to full frame without fear of having to spend a small fortune on new lenses.  It also puts pressure on the OEM's to reduce prices and improve quality.  That will happen if there continue to be more and more competitive lenses.

Nikon FF users should be very happy, since Nikon FF lenses are priced very high.  They are probably feeling this more than Canon is.

Thanks Dustin. :)
The lens appears to be what I was looking for, a compact good lens for travelling, this and a 16-35 II should be all I would need with my 5D3 for travel.
It will be interesting to see if Canon release a 28-300L II as rumoured and if so how it compares.

It's a surprisingly competent lens. I agree with whomever said that Canons replacement will probably not be a giant white lens. That doesn't really say "travel" at all. Even the color makes one more a target, while this lens (Tamron) is pretty much invisible.

I just returned from traveling and used the 28-300 VC almost exclusively (I also carried the 35mm f/2 IS for low light situations).  While the 28-300mm doesn't have the resolving power of the 35IS when compared side by side at a pixel level, I was very pleased with the overall quality of the images that I got on the trip with the 28-300VC, including this one:

Has anyone tried the new Tamron 28-300 for FF cameras yet?

If so impressions and comparisons with the Canon 28-300 please?
