Thanks for the replies.

Overall, the R2 Pro controller works well but the battery life is so-so. Turns out it specs for 1 pair of 1.5v AA batteries but my my Eneloops are 1.2v. Not an issue for the Canon speedlights or the R2 receivers, just the controller (the Flashpoint Li-ion has it's own battery). My options are to continue to use the Eneloops and change batteries a lot, use a non-rechargeable AA that delivers 1.5v or to try the few 1.5v rechargeable AA I can find. Anyone have opinions or experience with this?

I've been pretty happy using Amazon AA's (the higher capacity rechargeables). The measured voltage after 1-2 months in the bag is about 1.29v; that's the important number, as I have a ton of these, charge them at the same time, 32 at a time (four 8 battery chargers) and a lot just sit there until they get used.

<h3>Three New Lenses Deliver High Image Quality and Mobility</h3>
<b>MELVILLE, N.Y., April 2, 2018</b> – Canon U.S.A. Inc., a leader in digital imaging solutions, today announced the launch of three new portable zoom 4K UHD broadcast lenses<sup>1</sup>: the <b>CJ24ex7.5B</b>, <b>CJ18ex7.6B</b> and <b>CJ14ex4.3B</b>. These new additions are compatible with 4K UHD broadcast cameras that have 2/3-inch sensors. Flanking the existing UHDxs series of 4K portable broadcast lenses that deliver excellent optical performance, these three lenses usher in the newly launched UHDgc series that will broaden 4K UHD shooting options. These new lenses provide 4K UHD imaging quality at a price point that is more accessible to the majority of the broadcast market. Additionally, the new lenses provide impressive UHD optical performance while maintaining a compact and lightweight design to meet a wide range of needs for video productions that include documentaries, sports, events and news coverage.</p>
<p><!--more-->

The CJ24ex7.5B, CJ18ex7.6B and CJ14ex4.3B utilize Canon’s proprietary optical design technology featuring materials such as fluorite and Ultra-low Dispersion (UD) glass to achieve high 4K UHD performance across the entire zoom range. In addition, the lenses support the wide color gamut approved by the ITU-R BT.2020 UHD broadcasting standard<sup>2</sup>. These features are essential to HDR imaging. The lens ergonomics and digital servo operational controls are similar to previously announced Canon portable zoom lenses, providing users with maximum mobility in a variety of shooting situations.</p>
<p>“As 4K UHD origination becomes more popular in television news, the need for affordable lenses that can deliver the necessary imaging performance has grown,” said Yuichi Ishizuka, president and COO, Canon U.S.A., Inc. “The new UHDgc series of lenses provides the optical brilliance that makes Canon a leader in broadcast lenses, while at a budgetary level that will make them attainable to a large swath of the industry.”</p>
<p><b>Availability</b></p>
<p>The Canon CJ24ex7.5B and CJ14ex4.3B 4K Portable Zoom Lenses are scheduled to be available in summer 2018, while the CJ18ex7.6B lens is scheduled to be available in fall 2018*. In addition, the lenses are being shown publicly for the first time at the Canon booth (C4325) at the NAB Show 2018 in Las Vegas from April 9-12.</p>

We ourselves are unique - whereas most of our experiences are not. I value 1000x more a shot of a person who mattered to me, in a time long gone, than all but the very best shots of things or places (except where those places have also irrevocably changed and haven't been photographed by many others).

Could not agree more.

When I started photographing I studied and even visited some of the world's leading photographers to learn about their photographic philosophy.

My conclusion was that people are the most engaging subject by far so I decided I would "always" take pictures of people. The result has been that my pictures create a lot of popular interest and have been picked up by all kinds of media.

Today my pictures have probably eclipsed 100 mio. views. Of course any number of views does not reflect any photographic quality. But it does reflect that a lot of people like looking at people-centered pictures.

There are lots of remarkable and memorable/moving nature, landscape, macro, cityscapes etc. etc. But for pure human interest, people shots stand head and shoulders over all other subjects.

If you want to try a 135mm f/2.0 APO lens today, you can do just that with the Laowa lens. It's manual focus only, but I tried this one out and it's a really fantastic lens! Definitely want to get one.

So don't expect AF miracles with your new Canon 5DIII and your 1990 EF 85/1.8

Click to expand...

Funny you mention that. I have had my EF 85mm 1.8 since the 90's. Always hit and miss with AF. From a Canon A2e to Digital Rebel to 30D to 70D to 5DII. I now have a 5DIV and guess what, suddenly the AF is right on the money. From maybe 40% of all pictures being tack sharp, the rate went to probably 90% with the 5DIV. Unfortunately it's a little late as I just got a EF 85MM 1.4....

Actually I have had a similar experience with the 85/1.8 since moving from the 5DII also, but I got the 5DS rather than 5DIV. The reliability of the AF is greatly improved, and I'd agree with you, maybe 90% so it is useable whereas before the risk of OOF was just too great. However it is not as 100% on the nail as the 35/2 IS, 40/2.8 and also the 28/2.8 IS though I appreciate that it's not really a fair comparison in required accuracy.

Talys · Apr 1, 2018

@pj - I would definitely concur that the EFS 18-135 USM (Nano) on the 80D using PDAF is the fastest autofocusing lens I have ever seen -- period. It's so damned fast that many times in continuous autofocus I don't even notice the focus shift. For me, this is the gold standard of autofocus, and I wish all other lenses could be this fast.

However, three negatives about nano:

1. The EFS17-135 isn't as consistent as L lenses, sadly -- at least not my copy, based on FoCal. It's still very good, mind you, and near the top of the pack of non-L lenses.

2. The EF70-300 USM II (the nano one) is not anywhere near as fast. It's much faster than the old 70-300, but it's slower than current generation f/4 L's and f/2.8 L's; also, the consistency on my copy was horrible.

3. They're both focus by wire, and unfortunately, I think that's the fate and nature of Nano USM. Crocodile tears here, over that one.

Confirmed... replacing the battery fixed the clock reset issue. Thanks folks!

Although now I have two pet peeves regarding CPS service:

1) Canon never replaced the clock battery.
2) I discovered Canon never replaced the torn/shredded rubber eye cup (damage incurred during impact and noted on repair form).

Canon... the company I love to hate to love. *sigh*

Here goes another "dumb" question. I presume I can't do anything with the crane 2 from my Windows 7 computer and must use a phone to set the parameters to suit my liking due to lack of blue tooth??

My wife has the smart phone and says that when she went to download the app it said something about Google play and payment but I'll have to try to verify what's going on myself. With no phone of my own I have reasonable savvy of computer operations but not the phone (I know it seems trivial but there is a learning curve at the beginning)

Anyone else find the joystick operation to be backward by default - guess I function like a teeter totter. :-\

DON'T BLAME --ME-- FOR THAT !!!
I'm not the one who made those! I just got them from my usual Euro sources!

Sometimes tried to send the same rumors to Keith Cooper, maybe in hope to have a "rference", here what he thinks:

"Good to see the lack of solid camera rumours is firing up people’s creativity, but if you’re going to convince us, you need to dial it back a bit from a Canon smartphone with APS-C image sensor and EF-S mount or Canon mirrorless with MF sensors… As ever we appreciate tips, but try and keep the imagination in check ;-)" (http://www.northlight-images.co.uk/canon-camera-rumours-and-info/)

There are people who are good at spreading false rumors, others who are lame at that too...

Also: plugs/outlets -- I've checked my normal travel outlet sites and Japan's same plug but different voltage is a bit murky.

Some say some existing US plug items will work seamlessly while others state nutty things can happen.

Can some vet American --> Japan traveler set me straight on whether I need some sort of adaptor? I bring a host of chargers with me, including:

* Canon standard 5D3 single battery charger
* iPad / iPhone 6+ (i usually bring the quicker charging small iPad cube charger which will allow plug changeout)
* Laptop charger (PC, standard in-line transformer with grounded 3-prong plug
* Beard trimmer with standard two prong (no transformer in-line)

Can I use these as is? Just bring a 3-->2 US adaptor to manage the ground line on the occasional 2 prong outlets I'll find?

on my 2014 trip with a usa powered cpat plus all the chargers was all good.

no issuses but some hotel room cards must be put in a holder to power the room.

I was about to make another order of photo paper from Red River Paper. Up to now I've always used luster paper, with pretty good results, but I'm curious about trying cotton rag paper. I print mostly landscapes. Anyone have any opinions on the two compared to each other? I'm concerned the colors might be less vibrant with the cotton rag stuff, since I assume it's less shiny than the luster. But it's much more expensive than the luster, so it's gotta be better, right? ;D

Thank you, Keith. This is an excellent review, and perhaps the best comprehensive discussion of using a tilt-shift on a dSLR.

Thanks, I do prefer doing reviews of more unusual lenses - I don't have the patience to do all the usual methodical test chart stuff ;-)

@jolyon - I'm glad your adapted lens combo is something you're happy with. Personally, the autofocus would drive me nuts on a lens that wasn't very casual use.

Click to expand...

I know it's not perfect, yet, but there's absolutely no technical reason why it couldn't be perfect. Autofocus is simply a matter of controlling the motors in the lens to adjust the lens based on focusing information from the camera.

Assuming you know the protocols for the EF lenses (which are pretty well understood now) and for the Sony mount (likewise) it's simply a software issue to adapt one to the other. The only remaining issue is whether the body can focus fast enough.

And generally I only use primes with the A7RII so I'm not really missing the 24-70 much.

There ARE plausible reasons why the autofocus might not be perfect that isn't the fault of the adapters, such as the timing of communications protocols. It may be the case that the adapted lens is fixed to sending X signals at Y interval, but the camera body wants it at Z interval, without the possibility of change on either end. Then, the adapter has to make some electronics decisions, like throw some information out, perhaps resend some old buffered information, etc.

For example, if system #1 wants information at 0.07 seconds and #2 supplies information at 0.06 or 0.08 seconds, you can't square that. Even if it's faster, it is likely impossible for #2 to provide information at 0.06s, pause for 0.01s, and send another piece of information.

Obviously, it should be possible for the camera body manufacturer to fix that by making their body 100% compatible with another system in an emulation mode, but I can't really imagine that this is a priority for Sony.

cedric.ch · Mar 29, 2018

Thanks for your support.

The screws swapped is an option, I'll check them again. There's also a copper plate inside, I don't know whether the position is important or not. I think it's just a heat protection for the plastic as it was not even tight before.

I think what you did wrong was take the lens apart without knowing exactly what you're doing.

those that know exactly what they're doing are the one that at least tried once without knowing. I took the risk, hopefully, it will be successfull..

Have a good day, thank you.

Yes, I demand a high IQ quality (of course!).
I tested the 24 TSE with 1,4 TC III against 2,8/ 24-70 II at 35 mm.
Sharpness and CR were really better with the 24-70mm.
I can live with it but would really like to have a native 35 mm TSE lens (and know of quite a few colleagues who would immediately order it as well!)

However thank you for your experience, perhaps I repeat my test (hoping for better results).

But (owning and loving the TSE 17+24) I am still waiting for a TSE 35mm!!
For architecture 35 is much more needed than 50mm.

Click to expand...

Stop waiting. TS-E 24 f/3.5L II + EF 1.4x III Extender = TS-E 34mm f/5L with excellent IQ.

Click to expand...

Tried this combination, of course. I am not quite convinced of the IQ.

Then you are demanding an unusually high output and should be shooting medium format or even large format with a scanning back. I have seen the highest end hotel and resort campaigns shot with the 24 + 1.4TC and the resultant large prints were stunning.

I have been using the mirror lockup feature to reduce vibrations when shooting landscapes with my Canon 5D Mk IV, it has been suggested to me that triggering the cameras shutter when in live view mode would be a better option for stills. It would mean one less shutter press (via remote cord) per image, which would be an advantage when capturing landscapes with moving elements like waves. Are there any disadvantages in using this method other than obviously not being able to see through the viewfinder and increased battery usage ?

With live view, you never get a "blackout" where you can't see the subject.
