reviews of this new lens seem quite good. I would have liked to see some sort of weather sealing to make it a good lens to use in field.

I agree. I really wish SIGMA would start doing that to these higher end lenses. I'm not really sure what "Dust- and Splash-Proof Construction" means, especially because I don't see that on even SIGMA's website.

People always reply and say "well nobody uses it in the rain" -- sorry, not true. I live in the PacNW and its wet/moist/etc here and I don't just shoot in the dry-ish summer. And yesterday I was out doing couples photos for friends with my SIGMA 50 1.4 ART and it was drizzle to light rain. Really wish it had some sort of sealing. That's my ONLY gripe with these new lenses. They're fantastic otherwise.

Click to expand...

I really didnt understand Sigmas logic when they released Sport and Contemprary series of lenses with weather sealing while they excluded the Art series from it. I can understand they want to build ultimate no compromise lens in terms of performance so Image stabilizers got axed but weather sealing is just plain silly. I find it easier to protect the gear from rains( I use my gear a lot during monsoons in Western ghats and here when it rains it rains bucket loads) but moisture is what has killed my lenses and other electronics before.

This is what the forests of western ghats look like on a good day during monsoons:

I have already lost 430ex and 100mm L due to moisture in these forests.

I used to take a lot of shots in the rain forest in the film days. And yes - moisture kills everything. Brings in fungus too. Using Sicilia bags and plastic bags for sealing off your gear before/after use can save your gear (and your film... ). Also, be mindful of temperature swings! Walking into a dry, air-conditioned hotel room will increase the risk of condensation inside the camera a lot.

Btw Canon weather sealing does not imply rain proof - at all. It also does not protect against moisture developing in your camera.

Wow:
https://www.lensrentals.com/blog/2016/11/nikon-105mm-f1-4-e-mtf-bench-tests/

Sharper at f/1.4 than the 135L is at f/2 and nearly as sharp (again, at f/1.4) as the 100L at f/2.8.

That's impressive.

Click to expand...

The 135L is not perfect wide open. Dustin Abbott recently shared some comparisons to the new Milvus lenses which show the age of the 135L. It's good but in honesty not perfect wide open.

I must say that the Nikon 105/1.4 is sharper wide open than I expected. I thought it would be decent at f/1.4 but very sharp at f/2 and f/2.8. This one appears to be like the Canon 35L II... i.e. very sharp wide open and with low astigmatism, so perhaps it could also be good for "deep-sky" astro mosaic shots. We'll have to see if the low astigmatism translates into low "coma" as well or if f/1.4 will summon seagulls in the corners. At that price though the Zeiss 135 Milvus looks like better value for money.

I think that the users of big/long glass are a small proportion of all shooters, and that small group comes mostly from affluent amateur photographers.... the birding/wildlife/plane spotters... I do not know a single pro who uses them for work, but the birding community has them in spades!

Click to expand...

Actually, I'd honestly say that pros make up most of the market for long glass. The Associated Press alone has hundreds, if not thousands, of the 400mm f/2.8, 200-400 f/4 1.4x, and 600 f/4 just in the US and that's just one photo agency. They buy them as soon as they come out as well, and replace them as soon as they break. Now if you think about Getty, Sports Illustrated, the New York Times, and everything else out there, there's a hell of a lot of these lenses sold to newspapers. Sports photographers would probably also outnumber birders in general, and when you get into that, there's thousands on thousands of college, high-school, and professional sports photographers.

The newspaper I mainly work with specifically has the Nikon 300mm f/2.8 and 200-400 F/4, and that's a smaller-sized paper.

I'd say Canon makes most of their sales of 1DX and big white lenses off of these sports/news agencies that buy them in bulk. Getty Images brought about 35 big whites to the Olympic games, for example, and that's definitely a tiny part of their whole agency.

Not bad work on display here. I need to up my game.

Seems to me the real problem here is that Canon is applying lens corrections to an image for some lens other than what is attached to the camera. OK, they probably don't have correction info for Sigma lenses and even if they did I wouldn't expect Canon to apply them. But to modify images incorrectly seems to me to border on malicious. As a software engineer looking as some of the things Canon engineers do in firmware, I can assure you it's not due to incompetence on the part of Canon engineers that this image modification is happening.

Click to expand...

Sigma lenses identify themselves to the camera as if they were a similar Canon lens in order to get it working. I don't think Canon should go the extra mile to identify that the lens is actually a Sigma pretending to be a Canon and turn off lens correction.

I don't want to complicate the experiment, but I do have a question. Don't aperture and ISO change with different sensor sizes? My understanding is that focal length and aperture should be multiplied by the crop factor and ISO divided by the crop factor to get equivalence. This means for any given lens/aperture/ISO, you'll get a longer focal length, narrower aperture and lower ISO for crop sensors vs full frame. Do the results still compare apples to apples to apples?

Click to expand...

Yes they do. But the premise of the OP's linked article is specifically focal length limited situations where all images are cropped to the same fov, the same area from each sensor. Therefore effectively the same sized sensor.

In this specific comparison there is no equivalence calculation.

Hi Folks.
Wow, I thought this app was being left to expire, this is fabulous news, I do like this app. Off to update if my phone hasn't done it automatically, I haven't used it for a week or two.
Thanks for sharing this.

Cheers, Graham.

I am very happy with the 80d's AF. Whale watching, bird in flight, my toddler running around. All performed admirably. To me, the 80d's AF is comparable to my 5dmk3. 80d is definitely the right choice for most people.

Amazon is an authorized dealer, much the same as B&H. Both offer excellent customer service. Based on the limited information you gave, it's hard to pinpoint whether there's something wrong with the camera or with the settings.

I had a 60d many years ago. 80d's noise performance is significantly better. Hope things work out better once you receive another 80d. Post pictures with settings used if problems persist.

I can confirm that's not normal behaviour. Both my units store all their settings.

one more vote for an update.

In 2010, the lens (canon 70-200 2.8 is II) was brand spanking new, state of the art, cutting edge. Everything goes down in price after a while on the market. Now it's a lens that's getting on in it's production life. That's not to say it's a poor lens. On the contrary, I have one and it is fantastic. But the same lens released in 2018 would be even better, and cost more.
I agree with your main point- The Nikon lens is too expensive, but then, so is the Canon, which is almost the same price.
I might point out that the Nikkor 70-200 VR II still runs at $2100 vs the Canon which is at $1950, despite the Canon being a year newer. That might have been a more useful comparison to advance your point.

Click to expand...

So you think a 70-200 f/2.8 IS III would start at 2800? Based on the more recent releases of the 24-70 f/2.8 II and 100-400 II, I don't think it'd start that high. The Canon can be found for less than 1800. You're point was that the 70-200 II should cost around 2700+,when in fact is much less than that. The 11-24 f/4 lens is more complex than Nikon's PC 19 and still came out at a lower price. The market was growing in 2010, now it's shrinking. I think Canon understands that it doesn't have pricing power when demand is falling. Nikon thinks otherwise.

Click to expand...

Arrrg, man am I bad at explaining things!

No. no. no. that was never my point. My point is that the Canon was released at $2,700+ in 2010, after you calculate inflation. NOW it's an old lens, compared to the brand spanking new Nikon.
Yes I do think a Mark III would be around 2800-3000. In 2018, that will be less than the Mark II was at it's release, after inflation.
No comment on the 19mm Tilt-Shift.

I use the 24-70mm f2.8L II for work. It's just a brilliant masterpiece of a lens. I can't recommend it enough. So good!

I don't have the 35L f1.4 II but it looks to be equally brilliant. Instead, I have the Sigma 35 Art and the Canon 35/2 IS which are both fine lenses.

Very interested now that we know 16-35iii produces too much vignetting for astro work.

Click to expand...

I'm in the same boat, keeping an eye on this lens for astro. Do we have any info on price and availability? Haven't heard a peep since the announcement ... :-\

As for vignetting, I'll point out that the original Samyang 14mm f/2.8 was no rock star in that category, in fact, according to the TDP tests, it was very similar to the much maligned Canon 16-35L III (if anything, slightly worse):

http://www.the-digital-picture.com/Reviews/Lens-Vignetting-Test-Results.aspx?FLI=0&API=0&FLIComp=0&APIComp=0&Lens=1073&Camera=979&LensComp=1059

We'll see what Samyang did with the new Premium lens, but considering that the lens kept the same build and form factor, I wouldn't hold my breath for a great performance at an even wider aperture of 2.4. Hope I'm wrong, of course.

Click to expand...

You are right the 14mm f2.8 is slightly worse for vignetting but does have a wider field of view which makes it a little easier to crop off those corners. I'm interested to see a detailed coma comparison between the 16-35iii and 14 f2.8. Even if the 16-35iii slightly out performs the 14 f2.8, it costs nearly 7x as much. Interesting to see what this 14mm f2.4 costs and how it performs.

I am still waiting for replacements to prehistoric 50mm macro (with If and silent focus motors) and an update to 180mm macro.

Hi Halfrack.
In fairness the battery life test is done to a repeatable standard intended to replicate "normal" shooting conditions.
The scenario you provide is quite a long way from the average shooters setup.
I don't know which of this might be included in the standard, but the average scenario might be, IS on, AF on, image review on, default review time of 2 seconds some shots done in live view, tracking a subject with AIServo AF with the shutter button or BBF held on keeping the IS running, all of which will have a detrimental effect on battery life.
All that said I think the batteries generally last more than the specified number of shots although I have no research to back this up, it is more of a feeling.

Cheers, Graham.

http://www.canon.com/ir/conference/pdf/conf2016q3e-sum.pdf

As for interchangeable-lens cameras, in the third quarter, sales increased 8% to 1.37 million units
thanks to mirrorless models and new DSLRs

Canon, through the launch of new products, has been working to stimulate latent demand for
interchangeable-lens cameras. For the new DSLRs that were launched in the first half of this year,
like the EOS 80D, which offers improved capacity to track fast-moving subjects, and the EOS Kiss
X80 (EOS Rebel T6 in the Americas, EOS 1300D in Europe) with its enhanced ability to connect to
networks, have been enjoying strong sales. In addition, the EOS 5D Mark IV, the core model
incorporating a full-size sensor that was launched in September has been contributing to sales since
its launch thanks to the well-balanced basic performance it offers in terms of still and video shooting.

Furthermore, for mirrorless cameras, following the EOS M3, we launched an affordably priced
model, the EOS M10 last year. We continued to post strong results through carrying out focused
marketing activities by strengthening online advertising and our sales network. We were successful
in generating new demand among groups that have had little familiarity with inter-changeable lens
cameras in the past, such as women and young generations. Enhancing our lineup in this way, we are
growing our mirrorless camera market share in Europe and Americas, but especially in Asia, and this
is now beginning to serve as an underpinning factor that supports our presence within the entire
interchangeable-lens camera market

Huh. Stupid Canon knows what they are doing?

Growth rate YoY is -1% .. in other words, in a rapidly declining market - Canon is selling the same amount as they did a year ago.

Canon has sold now 4.37 Million ILC's through the end of September. We'll find out in a week on CIPA data, but that should amount to around or over 50% of all ILC's shipped this year.

The new EF 24-105mm f4L IS USM MKII will be a huge seller Ive had a chance to use it and I will definitely be buying it.

Hi RunAndGun.
Both my 7D and 7DII have this, you switch off and all the info disappears, pull the battery, give it a few seconds and it goes progressively darker, (but not black) and fuzzy, putting the battery back in causes an instant reversal, I guess they may have changed the way it behaves on the 5D IV.

Hi PBD.
One thing that carries on running with the switch turned off is the transmissive viewfinder screen (turn the camera off then look through the viewfinder as you remove the bttery) also there is no CR2025 battery in some of the new cameras, 7DII for example.
