I can't help with analysis of sharpness or AF accuracy, I can tell you that there are changes over time - the 24-105L that came with my 5D3 has a different body than the early ones. It's subtle, but for example the raised rectangular bumps for the AF and IS switches are much lower-profile than the earlier examples. Even car manufacturers sometimes make subtle changes in the same model and year with the same nominal options. It wouldn't be surprising at all if they managed to become much more consistent with their copy variation over time as well, just like semiconductor chip yields.

To really tell this you'd need to ask Roger really nicely to test an early batch and a later batch. And hope that it's a high-enough volume lens that they did make running changes to the production.

Re: Canon EF-S 35mm f/2.8 Macro IS STM Images & Specs Leak Out

I love when I see macro illuminators on TV. It's always some CSI dude taking crime scene photos fifteen feet away from the subject.

With a guide number of 46, wouldn't it work fine at 15" with f/2.8? Though I suppose they'd probably be using a narrower aperture.

For a very inexpensive alternative try out dxo prime (noise reduction). I resisted this product for 3 or 4 years, but when I eventually tried the trial version I was blown away. Where Photoshop noise reduction probably gives 1 stop extra, this gives 2.
With a Nikon D7200 I was getting images I would happily put in a wedding album at 6400 ISO....detail in eyebrows still visible in a head and shoulders portrait. At 12800 ISO that detail had gone.
I know we all like new gear, so do I, but this is a very inexpensive alternative.
Downside is such that the software takes approx 35 seconds to process one image and that is on a new high spec pc.

Re: Naming Canon's future mirrorless ~~monster~~ family.
Simplicity and Tradition are important for the "brand".
FF could easily be xM as in 1M, 5M, 6M...
APSc could become xxM as in 10M, 50M, 60M
Low end Rebels could become xxxM
The only weird current number is the fantastic EOS 7D. Just make it FF with high speed frame rates and automatic recognition of EFs lenses and perhaps digital zoom for the Birders

I will buy a 6M on announcement day...

I agree that tradition matters, but the APS-C cameras already have a naming convention- Mx (M3, M5, M6). Simply reversing the letter and number would be incredibly confusing.

I hope I did not make a mistake to order a 5DsR. I intend to replace my 7DII with it for bird shooting (mostly to be able to aim the flying birds with my 500mm and for some IQ increase). I have the 5DIV but I use it for low light mostly.

I have both the 5DSR and 5DIV. I absolutely love the 5DSR for bird photography for the extra reach and clarity from absence of AA filter. You have not made a mistake, in terms of IQ and AF, it's a real improvement from the 7DII.

Click to expand...

Question for you, not sure if you know or not, but - which is sharper, 5D4 + 1.4x extender or 5DSR w/bare lens? Or, even 5D4 + 2x vs 5DSR w/1.4x?

Click to expand...

It's something I know well from 100s of comparisons - the 5DSR is sharper with a bare lens vs 1.4xTC on 5DIV and with a 1.4xTC vs 2x on 5DIV.

There are good reasons for this. The advantages of the 5DSR are smaller pixels and absence of AA filter for resolution. The disadvantages are that the smaller pixels are more susceptible to shake and are noisier. But, if you put a 1.4xTC on a lens, the 40% increase in length increases the shake and the loss of a stop increases the noise, cancelling out the advantage of the larger pixels. The 1.4xTC does give some degradation of image and the 2xTC even more so.

OK Alan my 5DsR arrived just in time for my vacation. I did not have time to do AFMA (apart from some rough - non-scientific one). Now where are the birds that do modeling? ;D ;D ;D

Will you have enough power to shoot through the umbrella? If the cowboys are going to be far from the light, you could probably just shoot with a bare strobe / flash.

Niels' photo does show the infinity focus distance with the 12mm extension tube. It's a bit under 9 inches from the sensor, less than 3 inches from the front of the lens. Your subject needs to be pretty small at that distance. A 35 wouldn't produce a very flattering portrait from close distances either.

The 12mm extension tube on an 85mm reduces the infinity focus to about 2 feet and the subject still needs to be smaller than a human head - maybe eyes, nose, and mouth.

The 12mm extension tube on a 135mm reduces the infinity focus to about 7 feet and you would be able to shoot a head shot at that distance. Of course you could take a similar photo a few steps back without the tube.

So the real question is, what are your trying to achieve?

Sporgon · May 18, 2017

I think to day, more than ever, the influence of the photographer both behind the camera and in post processing dwarfs any difference in these systems, be it crop, FF, or DMF.

PureClassA · May 18, 2017

Really WANT to love the M system, but Canon's heart isnt in it based on the glass they have put out for it (or NOT put out. I hope the rumors are true about the FF MILC even if it's next year.

Seems to be out of stock everywhere in the UK too & Amazon who've had it in stock constantly now showing 'In stock on May 26, 2017' There appeared to be plenty in stock yesterday ... either there's been a rush on them or they've pulled it today??

I'm glad circumstances kept leading to purchase delays for me. Short of any other explanation, I'm guessing the inventory situation has to do with tweaking the lens: At some point there was a pause in production.

The comparison would have been more interesting if they had added to the mix the Rokinon/Samyang 135mm f/2, which is optically superior to the Canon, more-or-less as good as the Zeiss and Sigma, and can often be bought, new, for well under $500. The question for someone interested in the Zeiss (and who is thus presumably willing to MF) is not so much why buy the Zeiss when you can buy the Canon and Sigma for much less, but why buy the Zeiss when you can get essentially the same optical quality from Rokinon for $450.

Rokinon isn't spelled with a Z

I have the TG-4.... it travels in the pocket of my PFD and has survived countless excursions into the water and the rain. To my mind, why have a P/S camera if it can not do things your DSLR can not?

Viggo · May 17, 2017

I sent it back and it was declared DOA immediately. I got new one and it's silent as it should be and even better IQ and newer so very happy I sent it in.

<strong>United Kingdom, Republic of Ireland, 17 May 2017</strong> – A poll for Canon UK has named Roald Dahl as the greatest storyteller of all time.</p>
<ul class="c-circle-list">
<li>Roald Dahl has been named the greatest storyteller of all time, in a new poll</li>
<li>Canon on the hunt for a storyteller to spend a year identifying and living 365 new stories across the globe</li>
<li>Job of a lifetime applications being judged by famous storyteller, Zoë Kravitz</li>
</ul>
<p>Canon UK commissioned the research to mark the launch of its 365 Days of Summer competition to find a storyteller to spend a year identifying and living 365 new stories across the globe as part of its new Live For The Story brand positioning.</p>
<p>Roald Dahl, the creator of classics such as Charlie and the Chocolate Factory and James and the Giant Peach has topped the poll of the greatest authors, songwriters, artists and photographers. Visual storytellers including graffiti artist Banksy, Jurassic Park director Steven Spielberg and legendary cartoonist Walt Disney also featured in the top 50.</p>
<p><!--more--></p>
<p>The research also showed a staggering 94 per cent of adults enjoy a good story with the average adult telling four stories a day, through words, conversation and with photos.</p>
<p>Matthew Searle – Country Director, Canon UK and Ireland said: “You can’t beat a good story, whether it’s words in a book, photographs, film or simply through conversation. Roald Dahl in particular may be well known for his words, but the images which accompanied many of his children’s books have helped to paint a picture for children for generations.</p>
<p>“As technology evolves, stories are now so much more than just the written word and people today have a variety of ways to tell their story and make sure it lives on. Whether they are to inform, relay a message or just to entertain, there are stories which will go on to be told for generations to come. At Canon we celebrate storytelling in all its forms and with the launch of our Live For The Story campaign we want to encourage people to tell their story and live every experience to the fullest no matter how insignificant.”</p>
<p>Canon is looking for someone to fill a very unique position as it begins its search for the ultimate storyteller. The lucky person will spend a year chasing summer across the globe in order to identify 365 inspiring stories. Applications for this unique role will be taken via Instagram and judged by actress, producer, musician and storyteller, Zoë Kravitz.</p>
<p>The successful candidate will chase summer all over the world, visiting destinations from Lisbon to Melbourne to Brazil, curating their own story of the summer.</p>
<p>Those who think they have what it takes to inspire people to find their own stories can apply by sharing their most memorable summer story on Instagram with the story behind it (no more than 50 words), tagging @CanonUK and #liveforthestory. Submissions will be judged on a number of elements including storytelling ability, visual appeal, originality and inspirational qualities. The successful candidate will be required to travel the world chasing summer in order to identify 365 inspiring stories throughout the course of the job. The role is all expenses paid and, of course, offers a holiday allowance of 365 days per annum.</p>
<p>Canon’s storyteller will be tasked with identifying 365 new summer stories throughout the year, bringing back the art of storytelling and inspiring people to make the most of every moment in their life. The journey they choose is for them to decide, it will be their story to create and inspire.</p>
<p>Matthew Searle – Country Director, Canon UK and Ireland said: “Every moment has the potential to be important, even more so in the summer when we are open to new challenges and experiences. We are on the hunt for someone to inspire us, to help us ‘Live For The Story’ every day and ensure none of us miss those special moments.”</p>

To all participants: good luck!
And to the winner: good fun!

AvTvM · May 17, 2017

it may be no big deal for you. for many Canon users wrong turning lens rings are a real problem that could easily be solved/avoided by 3rd party manufacturers. they are making different variants of their lenses for different lens mounts already. so why not do it really right and match zoom and focus ring direction to the lens mount - by default! no big deal, neither technically nor in terms of cost.

wrong turn rings pn lenses are a telltale sign that tanron is not taking Canon users seriously enough. until tamron provides "really right" lenses, they should therefore be ignored and avoided by Canon users.

i have owned Tamron zooms and only realized after purchase in real use what a problem wrong turn rings can be in dynamic shooting situations, missing shots. insold those lenses and bought "really right". ever since i do my best to raise awardness of this problem in the hope that tamron and others finally deal with it. sigma has been moving and delivers some (many?) of their bewerr lenses with ring direction matching Canon mount (dont know if Nikon versions habe it wrong then or whether they really match it to lens mount variation).

tamron had been diehard on this subject until now, so onvioksly they need to be told more often and their lenses should be avoided by Canon users ... until Tamron gets it really right.

LSeries · May 17, 2017

Anyone here using this lens? How do you like it? How does it compare to Canon's 500mm f/4L I and II ? There seems to be many very positive reviews about the Sigma and the price is "tempting". I'm also already in love with Sigma's build quality seen in the 150-600 S.

The left side of the third chart appears marginally sharper. There's some color or temperature differences, however, as well as differences in contrast between the left and right side of the image. This can play with the viewer's perception of sharpness.

[/quote]

Good point; colour/temperature difference were I think due to my printer's dodgy B&W printing & the lack of contrast on the right side may be due to light from a window on the right...

Haven't got Reikan FoCal but now might be a good time to invest in it

I was looking in to it but seems it may have some issues with the EOS 6D ? See here: http://www.reikan.co.uk/focalweb/index.php/2013/02/focal-and-canon-6d-support-update/

" ... AF is very quiet and accurate. Of course, even when I reconsidered the image on the PC after taking the picture, I was not able to find the dissatisfaction like dissatisfaction at all. ..."

AvTvM · May 16, 2017

we are talking wrong direction of ZOOM ring here. For static scenes and for a few people it is no major isue, only disrespect for Canon user base.

In dynamic situations, e.g. all sorts of events, sports etc. it is a major PITA. Especially when you also use original Canon zooms intermittently at the same time. And when your body memory is tuned to Canon ring direction. As it should be with any Canon user.

Regarding camera meters not being able to meter at that shutter speed, if external, handheld meters can, then so should cameras.

30" at f/1.4 is EV -4. How many meters can go lower? An external meter like the Sekonic L-858D-U goes down to EV -5, just one stop lower. Canon 1Dx Mk II and 5D Mk IV just goes down to EV 0, so they wouldn't be able to meter that low.

Sure, 30" at f/11 is EV 2, so cameras usually meters, but in low-light conditions (including a strong ND filter), going past 30" even at full aperture very few meters will still be useful. So, it could be useful in manual mode, but expecting it to work in shutter priority mode and low-light won't work.
