WEX price £1599, I was expecting it to be £1799 in line with the dollar price  :o now where's me piggy bank

Wow, I was going to say just the opposite. Dollar price is roughly £1125-£1150. So you are clearly happier than I paying almost 40% more than our US friends. Yikes...

$1800 would be around £1330 with our 20% VAT added (£1108 without)
£270 Canon-Owns-Your-Ass tax sounds about right... Give it a month or so and see what Panamoz.com sell them for! They're similar to what ProCameraShop were and the Bank Transfer discount's way worth it!

Lenses / Re: Sigma 35 Art vs EF 35 IS in real life
« on: September 14, 2014, 05:48:49 PM »
Again, I know this is a thread about the 35mm lenses but I was intrigued to see the results shared by drmikeinpdx (great work, btw!) and the thoughts regarding shooting in tight spaces and trying to achieve shallower DoF, and feel inclined to share what I feel are advantages of maybe considering wider, fast primes... apologies for the rubbish compression (they're facebook server images) but this might offer some perspective on the 24mm perspective, which unfortunately isn't at f/1.8 when considering Canon's Stabilised offerings - more "aaaargh!" ;)

I'll not clutter the forum with lots of embedded images so here's a few shots from the 24mm Sigma, for those who care to click!

To throw a bit of a curveball for those who are trying to decide what's best... Sigma's (now old) selection of fast, wide primes are freaking awesome! They do a 20, 24 and 28mm, I think all at f/1.8 and the price increases as they get wider. I shoot with the 24mm f/1.8 and I'm honestly blown away with the results I get from it every time - oh and it focuses stupid-close, with expected W/A distortion of facial features etc, but what you can achieve with a ("macro" of sorts) close focusing, wide angle, fast lens like this really is fantastic. I'll try to dig out a decent example or two but I've got an image here from this past Friday which was shot with that lens on a 5D3, though cropped for composure...

Also - I'm torn with the 35mm IS thing too. It really is a bit slow/deep-field for my ideals but I'd also like something relatively fast and stabilised for video - aaargh ;D

...but for me, whilst I do see the general appeal of the 35mm FL, I go for a slightly less conventional Sigma 24mm f/1.8, Sigma 50mm f/1.4 & Canon 100mm f/2 trio for "Arty"/Low Light Event and Life-documenting photography... and for arty stills I feel this is a wonderful sort-of-budget set-up :) (oh, and Tamron's amazing, discontinued 17-35mm f/2.8-4 for UWA!)

recent image from the 24mm f/1.8 as mentioned above:

I'm not a fan of these things being labled 1" Sensors... I hope everyone considering this thing is aware it's much smaller than an inch and only around 15.9mm measured diagonally!

Go buy an EOS M instead ;)

I'm wondering how battery grips are going to look/fit with the significant curvature in the base design. Maybe a shorter grip that's not the full length of the camera or extra material to fill the gap?...

EOS Bodies / Re: Patent: Dual Motor For Autofocus on STM Lenses

Here is a translation from the linked source:

The continuous shooting speed reduction due to narrowing

Canon EOS system of several, including the adopted electromagnetic diaphragm, continuous shooting speed when you've narrowed down I will be lowered. Even without continuous shooting, release time lag of when you've narrowed down so lowered, It is a specification that anxious. Canon It is a thing of the patent applications that accelerate the narrowing and opening recovery time by two motorized. Reduction of continuous shooting speed by narrowing has been pointed out as disadvantages of EOS, but such concerns I might not.

Pretty bad translation, but it seems to make it clear that this patent has to do with increasing the speed at which the aperture stops down, reducing shutter lag, thereby increasing the maximum potential speed for continuous shooting.

I do not believe this particular patent is related to providing smooth continuous aperture control (which would be valuable for video)...it does indeed sound like a shutter lag related thing.

Thanks for the info, jrista! It doesn't appear to be concerned with video, with the emphasis being on acceleration, but I'm curious about past/current designs utilising stepping motors. Anyone know if this dual motor design is a first for STM incorporation in aperture control or is that element old news?

It's for step-less aperture operation, not AF

One motor (left) for normal stepping aperture in 1/3 stop increments, one motor (right) for smooth step-less aperture change.

More of a video recording gadget than still image.

Are we generally to dismiss things you have to say as pure conjecture disguised as certainty or do you know something contrary to the above information? Such a trait in life is only a hindrance to yourself and everyone around you who doesn't know to be more dismissive of you, consider doing that less, perhaps? ;)
The reason I say this is that the last bullet point clearly states one motor is to assist another with acceleration... and I apologise for being an ass to you but people have buttons, just like cameras do, and this kind of insistent tripe disguised as informed fact pushes mine in the context of people trying to gain an education and understanding.

But yeah, I'm a little surprised the CR folk didn't clock the word "Aperture" or recognise anything from the diagramme as aperture control hardware.

jrista and pin008 sound like they're barking up the right tree! Now I've to obsessively research these terms I don't know already; Canon EMD aperture? DCM motors?...

Also, if anyone's curious and isn't familiar with the design it appears that 7a are pins which the aperture blades pivot around and slot into 3b. 7b are little pins attached to the blades, these rest in 6a. Parts 3 & 7 rotate, 6 remains static and the blades open and close as the pins 7b travel along slots 6a.

I've aaalso just noticed the motors operate different cogs, 3a & 4A, hence their varying axel length (is 'axel' correct here?)
I'm wondering if 4 is perhaps relatively loose, offering enough friction to add to the acceleration but not so much as to be in conflict with the precision offered by the other motor?

EOS Bodies / Re: Canon EOS 7D Mark II Specifications Confirmed
« on: September 11, 2014, 05:21:06 AM »
I think at this point in time people are still going to have a lot of the rumoured specs in mind and accepting the final product might feel sort of like "settling" and anticlimactic until those ideals fade.
Here's a fun game, and feel free to add to the list or make corrections; what apparently hasn't the 7D got that people sort of maybe expected?!

* 1D Style Top Plate
* Built In Grip/Mini 1DX
* WiFi
* Higher Resolution Sensor
* Foveon/5-Layer IR-to-UV Sensor
* Touch-screen
* 12 (14?) FPS
* APS-H Sensor

I can see why, right now, people's spirits are dampened - but people were the same over the announcement of the 5D3 with its incremental rise in pixel count and that bitchery all melted away soon enough ;)

Still, I'm not looking at buying a 7D2 - The 70D with its flippy-floppy touch screen and WiFi is way more my kinda' camera :)

I heard that Canon had reached the limits of Zoom capabilities with the SX50 so they've had to engineer a negative-zooming lens to stay on top of the market. The SX60 shall have a -10x dezoom with nano-compression technology which forces photons into a plaited RGB braid which is only separable by Transgender Foveon Bono-X Technology developed by poached engineers from Sony Ireland and U2 which require hybrid stem cell sensors to be installed on the surface of the user's eyeballs via USB firm-hardware updates to capture the projected images of cuttlefish from the lens inversion as it retracts inside and then protrudes out the back of the camera to achieve its negative focal length, auto-mounting both your eyelids to the hot-shoe to prevent mass, energy and light leaks from corrupting the files on the third SD slot... or something.
There'll be a white one by Christmas 2015 and the battery will come with a sticker professing its own inadequacies, pleading that you buy it some friends for just $72 per 10mA. Please?

...and that 50mm IS guy might show up.

EOS Bodies / Re: Canon LP-E6N battery
« on: September 06, 2014, 11:28:21 PM »
I previously mentioned in a post that the battery almost certainly will have additional anti-counterfitting measures, and that future camera firmware upgrades may put them into place.

There is a distinction between a battery that claims to be a genuine Canon battery, and a third party battery that lists its own brand.  Canon firmware asks if a battery is branded Canon , and locks it out as counterfeit if the user responds yes.  If the user says no, then he can use the battery.

The issue is that the firmware seems to be unreliable and rarely detects genuine Canon batteries as counterfeit.

Either I'm way tired and reading that wrong or you've confused the frick out of me with this Alice In Wonderland Battery Conundrum. Tell me; what would the counterfeit battery say the genuine battery would claim to be?...

(now I  would love to see canon w/more DO lenses, but don't think it will happen)

Isn't there a new 400mm DO rumoured for this months announcements, or has that gone the way of the 100-400?!

Also, I'm quite happy hand-holding my 400mm f/5.6L, apparently that's not so impressive in this thread though ;)

400mm f/5.6L and the SL1/100D is a nice, lightweight pairing - though the shape and weight distribution can be a little odd. I had fun trying it out for a while alongside the 5D3, pretty much as a "1.6x Crop Digital Back" to grab out my bag as necessary and throw back in again, that thing really is "Super Light" - but ultimately I've been re-wooed by the 70D, with it's flippy-floppy screen, 1/3-stop selectable ISOs, weight, bells, whistles et al... Anybody in the UK needing to buy an SL1/100D? ;)

Third Party Manufacturers / Re: will the samsung NX1 steal the show?
« on: September 04, 2014, 10:13:17 AM »
I've got an NX11 (~14mp generation) and the NX1000 (20.4mp, i think?) and yeah, a lot of the above applies. Dodgy unfinished product wifi features, the modes change and hijack the screen to tell you about it when you're not touching the dial - But as far as lens options go, Samsung are all over that S___ in ways EOS M users dream about. The 16mm f/2.4 is fantastic (though I've take mine apart to piss about with on the EOS M) and the 30mm f/2 is brilliant, as someone's already mentioned. They also have a fast 85mm, some macro and 3D things and a very nice looking stabilised 16-50mm f/2-2.8 to go with this NX1!
Their JPEGs are abysmal for modern cameras though - lines and artifacts all over the place when you're not set up for bright sunlight. Their little flash unit is fantastic, tiny little shoe-mount-powered flippy thing and I got me an off-camera flash cable which makes it great for close up portraits with at-arms-length 45-degree type flash... I put masking tape over the front and it warmed and softened it ;)
