Or is Canon Rumors once again being scooped by his own readers.

In all fairness there's more of us that there are of him and he did provide us with a forum ;)

EOS Bodies / Re: Canon EOS 6D Listed as Discontinued at Amazon UK
« on: October 27, 2014, 10:18:38 AM »
I don't know too much (read: anything at all) about Canon's production strategies but is it possible they've simply pulled the 6D from the production line to bang out more 7D2 units, using the same manufacturing resources?
I guess that kind of thing could turn into "6D has been discontinued" after a few rounds of Chinese whispers, when they're really just intending to flip a switch next week to make the Canon Robot start spitting out 6Ds again?... no? Well I had fun fabricating such conjecture so I'm probably right!
As above, I don't see a new 6D rocking up 'til it's needed to poach some potential 5D3 resale transactions ;)

In other words.. JPEG just about the same as 70D from 100-6400, maybe 1/3 of an improvement, depends where on the picture you look. I was hoping they would improve noise reduction algorytm for JPEG.

Do we know if the JPEGs have default/standard High ISO NR or if they've turned it off? (ie. Not default settings)

That thing works wonders controlling chroma-noise on the 70D and SL1, sacrificing a bit of sharpness.
There's also a pretty sweet feature in the 70D and I think maybe both the SL1 and M where you can crank the ISO right up and the camera combines 4 shots into one hella-clean low-light jpeg! When I started playing with this feature I was really disappointed to see the 5D3 doesn't do this... but the 6D does! Getting back on subject: the 7D2 probably also has this NR feature ;)

Also, I'm pleased to see the 70D isn't totally defeated by the 7D2 - got mine for around £630 and I'm not feeling the near £1,500 7D2 is too close to seducing me into poverty just yet ;)

Ps. For a total of aroubd £15/$20 you could grab a Pentax or M42 adapter complete with AF confirmation chip and find an old 28mm f/2.8... I've got a Cosina(?) thing that's around the size of your 40mm pancake. Another wildcard, sorry ;)
Oh and you might need to snap off some silly aperture lever thing if you go the Pentax route..

28 mm is quite close to the 40mm I have, I don't know if it's really worth it to carry around two so similar lenses.

I will consider the 24/2.8. Nobody owns the Voigtlander? What about Sigmas?


Sigma's 20-24-28mm series of primes are fantastic - but I'm speaking as someone who likes to shoot people and activity within context, where these fast, wide lenses shine... but they're not light nor particularly small. I grab the super-old 35mm f/2, 50mm f/1.8 mk1 and for compact, fast reach 100mm f/2 (all Canon EF) as my multi-FL/multi-purpose travel/light kit. IMO possibly the best compact & lightweight compromise FF selection

...but I know you said ~24mm - sooo, I'm wondering if you have used and really want 20-24mm for these landscapes? Apologies if that seems patronising but I know from mine and others' experiences that longer lenses with fun framing can actually get much more pleasing results and (super) wide often just doesn't satisfy - but I'll throw one last wildcard out...

it's not small nor particularly light but do you think you mightvget more use out of a zoom like the...
Tamron 17-35mm f/2.8-4 ?! I love this thing and when it comes out to play it's pretty much as a 17mm f/2.8 prime for capturing super-close AND far detail, great for getting in your foreground grasses, textures etc... and for insane, unknown reasons this is both a discontinued and very affordable piece of kit :)

Re: the Sigmas: I'd generally recommend them for isolating close subjects from busy, wide backgrounds - for me that's animals and kids up close with pleasing bokeh and shallow DoF, otherwise they're big and heavy regarding your request, buddy!

If you do consider longer, that fast 28mm 1.8 DJL329 suggested or the 35mm f/2 are both small and awesome! I believe the former does vignette heavily but IMO looks great, if you're not one of those obsessive twonks we see on here who don't appreciate such artistic merit ;) DJL329's pics, to me seem both riddled with vignetting and awesomeness. Nice ;D

Reviews / Re: Gizmodo reviews the Canon 7D Mark II
« on: October 21, 2014, 12:08:17 PM »
To be honest, most 7D users I've met over the past few years have been people using them for applications for which a FF camera would be much more suitable: street, start-up event shooters, architectural/touristy or Urb Ex types, Fine Art students etc.
Simply, here in the UK we don't see too many Full Frame models in the bricks and mortar stores. The 7D had lots of "you are an awesome and creative pro for buying this camera" promo here and I noticed in Hong Kong too, being there in late 2009 - whereas the 6D, when and to whom its promo penetrates, is plagued with words like "entry level" and comparisons which certainly don't leave it on an "end user is awesome" pedestal. I've convinced one person who seemed genuinely interested in bettering his work to buy a 6D over the 5D2, some others insist they want the "higher end" 5D2 but I imagine they're the type who bought a 7D for super-awesome street shooting and I cbf interacting with them for too long.

I guess my input here is that I really do feel this kind of reporting is for the kind of people who'll buy 92% of these 7D2 units.
It's fantastic that there'll be lots of clued up folk out there loving their 7D2 and 600mm Tammy/Sigma shooting, dropping their robust kits off the jeep and into puddles out in the wild, these specs will do you good, I'm sure, but you're kidding yourselves if you believe the 7D2 club is going to be an exclusive Sports & Wildlife elite alliance... now lets get out there and sell, sell, sell! ;)

EOS Bodies / Re: Patent: Canon 2mm f/1.4 Lens for Small Sensors
« on: October 18, 2014, 04:46:30 PM »
I wonder how wide a (very improbable) full frame 2 mm lens would be...
I cant even imagine. This is what a 6mm lens looks like...a 2 mm lens would probably have to warp back over the camera body



The 6mm lens is a circular fisheye, and for that focal length has to look backwards.

A rectilinear lens can't have an angle of view wider than 180mm, so it couldn't possibly look back.

This is the post-Einsteinian 21st Century - I demand greater physics! I reckon there's a visual equivalent to the Sonic Boom to be discovered, if only we can shave a few more millimetres offa' these UWA lenses...

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!

Lenses / Re: Sigma 35 Art vs EF 35 IS in real life
« on: September 14, 2014, 04:42:49 PM »
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 :)
