Dustin, do you know what the pricing for Canada is?

Not yet.  I wouldn't be surprised to see either $1099 or $1199, but I will know for sure in a few weeks.  I have been told that I will have a copy in hand by the first of the year.  I'm excited to try it out, although I wish it were a better time of year.  Wildlife in January is, well, sometimes hard to find!

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

One attribute of this lens that doesn't seem to get mentioned much, perhaps because it's not exactly fast, is how well it performs in low light - at least when attached to a FF body - when merely taking hand-held snapshots.  A week ago I was wandering around NY with my 5DIII & 70-300L (I left everything else in the car) and ended up in Central Park as the light began to fade; and as it did, it began to snow.  The light was magical and the camera/lens combination did a rather good job of capturing it.  (They also did a rather good job of ignoring the snow - I had nothing to protect them with, not even an umbrella, so I just occasionally shook or blew the snow off as it accumulated and kept going until I decided to stop a couple of hours later.)   No noise reduction despite the rather high ISOs (I think the grain enhances the look).  The results could perhaps have been better with a faster lens or a tripod or someone better behind the camera, but none of those were available....   These four are in Central Park.  In the next post I'll add three from a bit farther south.

These are lovely, and I agree about the lens.  The 70-300L is much better in reality than what it appears on paper.  It will be overlooked by many because of the variable aperture, but it is a special lens.  Great use of it!

I'm hoping for a lens that can live up to the IQ of Tamron's more recent releases (the 24-70VC and 70-200VC), but at only $1100 I'm also quite skeptical. I would have preferred it if Tamron spent an extra $200-300 to make a better lens (e.g. better glass, improved durability). Even at $1400 it would be still be a compelling alternative to the 100-400L if it could keep up optically. At $1100 it seems like the aim was more to be the best third party long zoom than actually compete directly with the 100-400L.  :(

Who knows, lets wait for the reviews...

While I don't entirely agree with you, I will confess that a somewhat similar thought has been in the back of my mind.  The release price for the 70-200VC was $1599, the 24-70VC was either $1299 or $1399.  With the size of the front element I can scarcely see where production costs could be lower on the 150-600.  And yet Tamron is claiming weathersealing, robust build, and new technology in the glass.  We'll see.

If it turns out to be a fairly good lens, however, Tamron is going to sell a LOT of these.

6D + 24-70 f4 IS.

Shot on the Sussex coast at Adlebrough. A three frame stitch hand held, ISO 320.

Nice image.  I haven't seen much from the 24-70 f/4.  How do you like it?

Many thanks Click, Edward and Dustin.

The only thing that makes the 24-70 IS difficult to assess is the cheaper price and even cheaper availability of the 24-105. The 24-70 IS is the better lens, especially mid frame and in the corners; it is really prime quality most of the way, whereas when you take the average of the 24-105 across the frame it lags behind the primes. The lens is very compact, in practice significantly shorter than the 24-105, and the manual focus quality is a little better. The IS is meant to be more effective but I haven't enough evidence to come to a decision yet.

Reviewers of the lens have stated it is not as good at 50mm. We haven't found this.

In summary I would say if you want prime quality in a zoom but also need IS get the 24-70 f4L IS.

Here's a picture of the pool at Flatford Mill and 'Willie Lott's cottage made famous throughout the world by the most famous of English landscape artists John Constable with his "The Haywain" oil painting finished in 1821. Now owned by The National Trust the area has been preserved pretty well since then, but the pool is deeper now because the Eastern part of England has sunk one foot lower over the last two hundred years !

Shot with the 6D and 24-70 f4L IS @ 50mm. I'll put an example of this lens at 50mm @ 100% in the 24-70 IS image gallery.

The color here is really, really nice!

35 L II and the 50 f1.8 IS  8)

+1

Could also be update of 135L, but 35L is in more need IMO.

+1 again  8) These 35 and 50 mm lenses are direly needed to upgrade Canon's lens line-up.

I'm in agreement here.  These are both holes that need quick plugging, particularly considering that the Sigma is ending up in a lot of bags, and, for others of us, the new 35mm f/2 IS is actually in many ways superior to the current 35L.  It is my most recent addition.

Count me in for wanting the new 50mm.  I don't have an AF 50mm in my kit right now because I was never blown away by the (non L) 50mm choices.  I have owned and then sold two copies each of the 50mm f/1.8 and 1.4.  I have never bought the 50L because of both its own shortcomings and high price.  I make do with some vintage options (Takumar and Helios), and really enjoy those lenses.  But for a lot of work AF is really needed.

This is the entrance from the Solomonic period in Tel Megiddo.  They have uncovered 26 layers of human civilization here.  Amazing to walk on stones laid by King Solomon's workers more than 3000 years ago...and the history in Megido goes back much earlier!

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?

you'd be surprised the lengths some men will go to win a pissing contest

never underestimate the ego and its wallet :D

LOL.  I'll gladly take a loss here :)

I really don't see a need to question Dustin Abbott's integrity on lens testing.  I would argue that large magazines and websites that make their money through advertising by big camera companies, or click-throughs  to stores  have more to gain by biased reviews. 

I think *all* reviews should be questioned, not so much because of intentional bias, but because of testing variations, and as mentioned by previous posters, variation between copies, esp. w/big glasss.  when the lens is out, we should have 5 or more reviews to look at, and unless there's some conspiracy, we should get a consensus on qualities based on bench tests.

My only concern is how will this lens work for me.  That's not just theoretical, it's practical.  For example,   I do not use a tripod, I shoot either handheld or with a monopod.  So even if I had a sharpest lens ever made, I would introduce some shake which would affect results.  I value a fast and effective stabilization system and that's my biggest hope for this lens.  I'm sure it will have to be stopped down at least one full stop for optimum optical sharpness, and that it will *not* be sharpest at 600mm.   So, the question is...how will this work for me at 400-500mm compared to a more expensive 100-400 L? or the Bigma???  I think we'll all find out soon and that will end the some of the speculation.

Good points, and one of the biggest reasons why Roger's conclusions are LensRentals are so valuable.  He has access to more copies than any reviewer I know, and I trust his assessment on the technical end.  My reviews are more about real world use, and are much less useful scientifically and hopefully a little more useful for those looking for practical application.

There has never been any attempt to bias my results, and, since my primary occupation is as a pastor, I do value honesty.

Just to be clear, I'm not in any way suggesting dishonesty or bias on your part.  What I'm suggesting is that if you're testing lenses provided directly to you (as a reviewer) by the manufacturer, your results may be biased through no fault of your own, but due to the manufacturer hand picking and pre-testing the lenses you receive.  Also, pre-production lenses, by definition, aren't representative of lenses that come from the established production line.

If you like the lens well enough to purchase your own copy, I trust you will update your review if the production lens you buy differs substantially from the preproduction lens Tamron sent you for testing.

Absolutely.  I have ended up purchasing retail copies of several of the lenses that I have tested.  I have also updated reviews both on my website and on threads here with comments about issues that I have encountered with lenses/equipment after review.

Even my contact in Tamron Canada is surprised at how quickly this lens is coming to market.  They initially expected a longer roll-out period.  I am somewhat skeptical that the copy I get my hands on will be a pre-production copy with the release date now not much more than a month away.  I think that ship has sailed, and whoever shot these samples were using the pre-production units.

I downloaded all of the sample TIFs from that page and examined them full size in Lightroom.  A few observations:


  • The BIF shots were all taken with a 1Dx, and it seems to be an earlier version of the lens because it just registers at 150-600mm

    The latter shots were taken with a 5DIII and the lens registers its proper name

    Sharpness at 600mm f/6.3 is not astounding, but it is far from bad.

    I have no question that good samples were chosen, so obviously YMMV

    Both color rendition and bokeh in both the highlights and the transition zone look quite good to me for a variable aperture zoom

    I'm glad the samples include BIF shots.  I hope this indicates reasonably good AF

    They are TIF files, and there is 0 sharpening on import, but I suspect they were sharpened before being flattened in PS because haloing appears pretty quickly when adding more sharpness in LR

    Stopping down even a bit seems to improve sharpness (in the samples) at 600mm

I downloaded more of those TIF files, and I have to say that I'm pretty excited for this lens.  I'm not a birder or a real wildlife shooter, but if I could get this kind of reach with fairly good image quality it would be very appealing to me.  My investment would be more in line with the amount of time that I will actually be using the lens.  This is the reason that I have never purchased one of the great whites; I just wouldn't use it enough to personally justify the expense.  But absorbing this kind of cost even it only accounts for 5% of my overall shooting would be a different story.

+1....however, there are some buy $10,000ish lens and mount on $2000 - $3000 cameras ;D

I did think of that, but we aren't exactly talking about the same market.  I personally will never pay big bucks for a lens that can only be used on the M.  I would prefer to spend that money on an EF lens that I could then adapt to the M if desired.
