EOS Bodies / Re: APS-C Camera with an L Lens as a Kit
« on: September 11, 2011, 04:13:55 AM »
I'll presume you've done your research and just want a 7D + 24-105 for your use (although personally i got the 15-85).

at my favourite european shop:
24-105 €1049
7D body €1329
5D2 body €1895
7D + 15-85 €1949
7D + 24-105 €2278
5D2 + 24-105 €2595
5D2 + 24-70 €2955 (for comparison)


hmmm, wow. i'd get the 5D+24-105L as well for those prices. 7D kit is only a hundred euro less than the parts, the 5D2 kit is 450 less than the sum of its parts.
of course, that's assuming noone here convinces you to get the 15-85 or 17-55 instead...

EOS Bodies / Re: Where are the BIG information leaks??
« on: August 28, 2011, 12:31:34 AM »
but where are they testing them, and how can they account for the public? almost anywhere you go these days with a big camera, you're going to turn heads, and if one of those heads is someone like me, i'll be looking a bit closer to see what equipment they're using.
So are they testing them out in nature? every time i go for a walk somewhere i think is secluded enough, inevitably i'll run into someone else with a camera, maybe a P&S, last time it was a nikon guy with a macro lens and ring flash up a hill 4km from the nearest road, 50km from the centre of the city.
or are they huddled in a studio, maybe taking portraits where noone else sees the camera but the models and makeup artists (who probably wouldn't know the difference between a hasselblad and an iphone)

even if the testers have signed NDAs, the public hasn't. probably the models even haven't. is it just that lucky that noone's spotted anyone using one?

I do not understand :-/  The time to precision-grind glass?   Umm...

Don't forget the time to actually grow the fluorite crystals before grinding. The 1200 f/5.6 allegedly took nearly a year to grow the crystal for each lens. The fluorite lens in the 400 f/2.8IS mk1 doesn't look nearly as big, but i wouldn't be surprised if it took a few weeks to grow...

EOS Bodies / Re: 1Ds Mark IV & 5D Mark II Merry-Go-Round
« on: August 26, 2011, 08:32:37 AM »
Seriously, 24-70 has to have IS or else myself, and thousands of others, will have no reason to buy it. Fix the field curvature also.

But what if they do one but not the other? IS with curvy corners? flat-field with no IS? How many of you would ditch your current 24-70 one for either of them?

And the "specialist" lenses, i'd like the idea of new TS-E(s), but does the 200-400 1.4x f/4 count as "specialist" enough?
How about an MP-E 65 mk2?

Canon General / Re: Silly question by a noob
« on: August 26, 2011, 08:25:41 AM »
a) you have 21MP in a FF sensor, and put 9 (or so) of them together into one 'video pixel' across the whole sensor.
b) you just make a 2MP FF sensor.
All things being equal (like using the same technology, gapless microlenses etc), and using the same lens, you get exactly the same DOF, Noise, Sensitivity etc. (maybe a bit less power draw? if so maybe a bit less noise from self-heating?

If you eliminate the mirror, take out the shutter (ie remove stills capability) then it'll be cheaper too. But then you've just made a dslr-shaped video camera...

Smart thing for canon (or anyone) to do in bringing out a dedicated interchangeable-lens video camera is to make it either use their dslr-mount (like EF-mount), or make an adaptor so that you can mount dslr lenses on the new video camera.
And there's only one real interchangeable video lens-mount, Arri PL, and that's got a long enough flange distance that you can mount it on almost any new-mount video camera to come...

Canon General / Re: Panasonic, I love you!!!!!
« on: August 26, 2011, 06:55:38 AM »
Did not the powershot G10 have 14MP, then the G11 and G12 down to 10MP, adding a different screen and video?
Did not the 14MP SX210 update to the SX220/230 with gps and double the screen dots, and reduce to 12MP?

Canon General / Re: So... Sony just dropped their Juggernaut!
« on: August 24, 2011, 07:25:29 PM »
So it's APS-C, and $1400, so going to compete against the 7D basically.
24MP vs 18MP win.
12fps vs 8fps win (even beating the 1D4 there).
GPS vs none win (but lose if you don't care and can't switch it off to save battery life).
50/60fps 1080p video win. (but only 28MBPS, up from 24MBPS in 24/25fps? more compression = bad?)
19pt AF/11cross vs 19pt/19cross lose (just on numbers, we'll see how well it works later).
In camera-panorama win if you like it, don't care if you'd rather stitch in-PC
Sensor-based IS win for old lenses, lose for battery life and heat.
ISO 50-25,600 (I always remember a TDP quote, just because you can, doesn't mean you should).
Selectable ISO range in AutoISO win (my mum's 6-year old IST *DL can, 550D too, why can't my 7D?)
5-frame AE bracketing win.
1200-zone metering win? 7D is 63-zone in viewfinder, not sure about in live-view.
30-1/8000s, 1/250s flash same.
Flash GN 12 (i think 7D is GN15?)
Buffer 13 JPG shots big lose (maybe blame the SD card?)
Battery life 400 shots viewfinder lose (7D is 1000 shots i believe).
Electronic viewfinder lose for me, battery life and dark-tracking main reasons. Depends if it's worth the extra 12FPS to you.

Ergonomics are always personal, and you'll learn to use what you've got after a few months. Personally, i'm sticking with my 7D. But yay for Sony, hopefully it's lit a fire under their 7Dmk2 development team, I expect nothing less that 28MP 9FPS 25ptAF for $1500 now.

1193
Ditto. Why does it say 'Rebel T3i' next to my name?

Surely that should read 'EOS 600D'...?

Canon General / Re: High shutter count on brand new 60D!
« on: August 21, 2011, 06:59:41 PM »
You might be able to check out the shutter count using this program:

http://astrojargon.net/EOSInfo.aspx (windows)
http://astrojargon.net/40DShutterCount.aspx (mac)


and on linux it's the easiest, with gphoto2 (which you need to download pics from camera anyway)
> gphoto2 --get-config shuttercounter
(maybe this has been ported to mac? could happen, it's all unix these days)
Not sure why canon don't put that kind of information retrieval in the EOS utility for Win though...

Lenses / Re: Lens for a big sun in the pictures
« on: August 20, 2011, 09:40:26 AM »
I wouldn't say there's anything wrong with using a mirror lens for shooting into the sun, you'll be focussed at infinity and won't really have a chance to see the doughnut-shaped bokeh. They're also really light and easy to hold (but i'd be using a tripod anyway).

There's some other really long lenses on ebay i wouldn't touch with a bargepole for IQ, but if you don't care how sharp it is, i've seen things like a Rokinon/Bower/Opteka/Phoenix (ie, all rebadged Samyang) 650-1300mm f/8-16 for about $200-300. Manual focus only (but so are mirror lenses and using heaps of teleconverters), really really slow so useless for wildlife (but you want to stop down a lot for pointing into the sun anyway).

For a shot like you've got, a Graduated ND might be useful, you can darken the sun enough to get details in the buildings (if you didn't use one already, whatever you did for that first shot looks good).
And don't use live-view for focussing, i blame that for giving me dead pixels. (wear sunglasses for viewfinder focussing too maybe, so you don't ruin your eyes)

Lenses / Re: Samyang 24 f/1.4 is coming
« on: August 17, 2011, 04:44:42 AM »
A low price tilt-shift lens would be very very tempting.

Pentacon Six Tilt adapters are $100 on ebay, zeiss lenses $1-200, soviets down to $30. But nothing (good) wider than 50mm though (except 30mm fisheye)...
(and only tilt or shift at once, unless you shell out a few hundred for a zoerk adapter)

So if optical quality of the Korean counterpart is just equal, that would be a "revolution" in the T&S little world!!  :P

i don't think anything's going to come close to the TS-E 24mm vII for resolution, even from canon themselves. But if Samyang can pull off the IQ-level of the 14/2.8 into a TS-E model for even half the price of the canon, i'd get one...

Lenses / Re: Samyang 24 f/1.4 is coming
« on: August 16, 2011, 11:21:56 PM »
On photozone.de where they've reviewed the 8, 35, 85, all of them are pure old-fashioned turn-a-ring stop-down aperture, so i'm guessing the 24 1.4 would be too. But you gotta expect some shortcomings for the prices...

1198
Is it me, or are canon's websites making more and more 'mistakes' recently?

or are we all just looking harder?

Lenses / Samyang 24 f/1.4 is coming
« on: August 16, 2011, 08:17:06 AM »
They've already got the 8mm fisheye, 14 f/2.8, 35 f/1.4, 85 f/1.4.
Now they're bringing in the 24 f/1.4.

My predictions: MF-only is fairly certain, centre should be sharp and corners maybe a bit fuzzy, 1/4 the price of the canon L, same size and maybe a bit lighter. Who wouldn't want one?

EOS Bodies / Re: Buying a refurb 7D
« on: August 16, 2011, 02:52:23 AM »
Apparently, Canon Europe sells refurbs via eBay.


i've heard this a few times around the place, and finally figured out where. ebay.co.uk and search for 'canon refurb' turns up the seller 'canon_uk1'. currently 170 items up, a 5D kit, 24-105L, 17-55 f/2.8, 70-200 f/4L IS, and a crudload of pixma printers and Ixus cameras.
Postage only to UK, hence i couldn't even find it using ebay.nl where i'd looked before. maybe my sister in London is going to be receiving a few boxes in the mail for my mum to bring home with her to Aus when she's up there end of the year...
