Canon General / Re: Nikon to launch D800 D4 this Month?
« on: August 02, 2011, 07:26:24 PM »
So the conspiracy theorist in me is wondering, was the Gigapan leak accidental? Nikon's D4 announcement seems to be a bit more concrete and possible than canon's 1Ds4.

"So why wouldn't I buy a D4 on release? Ah that's right, because the 1Ds4 is just around the corner, right, Gigapan already have a casing for it, it's not far off, I won't buy that D4 until I see what canon have to offer..."

and did someone see the hot shoe  :o ;D

I was wondering about the hot-shoe too. If it were a canon flash on a canon body, there'd be no need for a synch cable.
But seeing as they rebadged it as a nikon, they needed to continue the lie by adding the cable, coz a speedlite 580ex (v1 by the looks) might not like working on a 'nikon' body...

or is it a trick question? isn't the 'sacrilege' that torchwood is still showing on tv?

So they've got a canon flash.
nikon body (or a different body with nikon photoshopped over?)
and photoshopped nameplate so they don't advertise a specific model?

EOS Bodies / Re: Cleaning?
« on: July 31, 2011, 03:13:28 AM »
yep, what everyone else said so far. I've cleaned my sensor maybe 2-3 times a month since i got my camera (but i use it all the freakin time).
I also shoot a lot of pinhole (f/170) which shows up every single speck of dust bigger than a pixel wide.
First step is just a blower, test shot at the smallest aparture you can get (long end of a zoom might get to f/44), ISO100 at a white wall or cloud, move the camera around a bit to blur the photo and the dust stays sharp, maybe repeat once with the blower.
If that doesn't work, I use Visible Dust Swabs (which is what my camera shop had in stock at the time). Try to avoid the temptation to use your blower to dry the sensor, it makes it worse in my experience. Normally it takes 3 or so shots with the swabs before it's properly clean. I've never used another brand, but these work perfect for me, i'm buying them again.

One thing to remember, microfibre cloths are great for the front of your lens. Never ever use it on your sensor (i know someone who had to get a new bayer filter on his sensor when his finger 'slipped' doing that).

« on: July 28, 2011, 08:35:36 PM »
edit: damn. eos 7dsv is not a video thing i've just discovered, was announced last year and i missed it...

but yay for 1dsmk4, it can't be an easy typo because all the dimensions are different to everything else...

Canon General / Re: Switching to Nikon
« on: July 27, 2011, 07:16:43 PM »
I find that Nikons have a much better button layout, however, their camera ergonomics are lacking. Canon has great ergonomics down to a "T". For me this is important because I have tiny hands and weak wrists. Other people may not notice the difference so much. Good ergonomics is the difference between my arms getting tired and shaking, and me taking a good picture without getting exhausted in a few minutes.

This point doesn't even have to be about Canon vs Nikon, it goes for Canon vs Canon as well. I've got a 7D, main lens 15-85. I've got the custom buttons set up how I like (like top-dial does Aperture in Av and M mode, joystick does AF point select (i leave it on 5-spot most of the time). I take most of my shots without moving my eye from the viewfinder, except thos MLU shots (which i MF on live-view anyway).
After owning it for 6 months & 10,000 shots, i tried my sister's 550D with 18-55IS kit lens, and I couldn't get used to it at all. no wheel, no joystick, nothing was where i wanted or expected it to be. but she's had it also about 6 months, and can take photos just as fast as I can without moving her eye from the viewfinder.
Ergonomics is just something you get used to, imho. but my sis has tiny hands compared to me (she's only 5'3" or something, i'm 6'0). 550D fits her hands, 7D fits mine. I've never tried a nikon for more than 20 minutes, but i'm sure there's a model that fits my hands somewhere, the rest of it may take getting used to, but it'll happen if you want it to (and as long as the functions exist 'somewhere' in a menu, you'll get fast enough at activating them).

Lenses / Re: Why not EF-s "L" lenses?
« on: July 26, 2011, 07:41:28 PM »
Someone with a good number of EF-S lenses will have to answer, but from what I understand, there are many high quality EF-S lenses that are optically on par with L lenses.
The efs 15-85 and 17-55 f/2.8 are both very good, a lot of people say the 17-55 is better than the 24-105 f/4L for the same focal length, IS, and effective aperture.
But just being an 'L' doesn't especially mean it's flawlessly perfect, look at the corner softness of the 17-40L, 35/1.4L, 24/1.4L. Look at the field curvature of the 24-70/2.8L. Look at the barrelling of the 28-300L @28mm. Compare the MTF sharpness of the 50/1.4 and 50/1.2L (yes, the f/1.4 has its own problems though).
But then, look at the release dates of some of those lenses. Also, pushing the boundaries of useful lens design leads to compromises, like the ultra-fast apertures, or extreme zoom ranges. They'll get better with new revisions, and it's not like any other company can do any better (and make it affordable).

Some say the 17-55 f/2.8 should have been 'L' designated, for its quality. Maybe, but what's the difference? If it's L, that doesn't mean it will automatically be weather-sealed. And weather-sealing is probably the only L-feature that lens lacks. Adding a red-ring won't mean anything to anything except the price (and maybe the stealability).

Also consider, it came out before the 7D. Before the 7D, nothing APS-C was sealed (to that degree at least). 7D is a sports/wildlife camera, not landscapes. Buying a 7D for sports/wildlife generally entails a weather-sealed telephoto L lens, 70-200 IS, 70-300L, Big White Primes etc. Buying any less is a waste (i found that out with the 70-300nonL).

Sure, you _can_ use the 7D for landscapes, i've taken some good ones with my 15-85. But the 5D2 in the same spot will probably take a sharper shot in most circumstances (and i can't afford a 5D2). But still, the 7D is not a 'dedicated' landscaper, it has its specialties elsewhere...

because a red ring and a white square would look weird together.
Doesn't look so weird with my 70-300L on my 7D.
How about an EFs L with a white ring?

Otherwise, get L prime lenses and use them on your 7D.
Yep, that's surely not a mistake by their marketing department, that's what they want us to do no doubt...

Lenses / Re: IN Lens Stabilization
« on: July 26, 2011, 05:27:47 AM »
everytime i buy a lens i am buying another image stabalising system and so a degree of duplication as i can't obvioulsy use 2 lenses at the same time.


Same idea with Autofocus, Nikon (and Pentax iirc?) went the road of AF motor in the body, and drive with a screw. Then they gave up and put the AF motor in the lens (after they realised it's faster), and stopped putting the motor in the cheaper bodies, so it's a crapshoot buying nikon lenses and bodies unless you research well first.
But that made sense, in a way, lower-end-camera buyers only buy 1 lens and 1 body, cheaper to put it in the lens. Pros who keep their glass for 20+ years will want to AF with their pro body, so they still get an AF motor in-body.

As for IS, pretty much the only plus is that you can IS with any old lens up to 100 years old that you can adapt to your body. And for someone who buys a lot of glass vs bodies, buying non-IS glass can make a decent cost-saving.
Everything else is a downside though, worse performance because it's not tuned to the size/weight/focal length, overheating easier, and not active in the viewfinder annoys me no end for long slow handheld lenses.

I do hope that Tamron Idea gets up and running though, if it's got the IQ and performance to justify the cost, then you could use any non-IS lens, on any DSLR, and you get the best of both worlds (the only downside left would be that it wouldn't be tuned for individual lenses, so not as good as in-lens, but probably better than in-body)

Canon General / Re: shutter noise in 1DMark III
« on: July 24, 2011, 08:36:50 PM »
Is it the shutter, or the mirror?
I'm not sure if mirror lockup work in high-speed continuous mode though.

On my 7D, there's a "silent shooting" mode on liveview, the shutter makes less sound, but one (or both) say not suitable for HSC. Read your manual, it's probably different to the 7D.

If it's just the mirror making the noise and the shutter isn't so bad (my experience is that the shutter on its own is no worse than a whisper a few meters away), then my solution would be to Manual Focus in live-view (or viewfinder focus then activate liveview), and let fly with HSC when he swings for the ball.
At least it's golf so subject is static, not running all over a field... :)

Lighting / Re: Yongnuo YN-565, what's the delay?
« on: July 24, 2011, 07:45:26 PM »
Some companies are overly optomistic about their ability to develop and produce a product.  Sigma comes to mind.

Even Canon who has been conservative about doing things like that was burned after announcing the big whites and falling flat on their face.  The earthquake only made a bad situation worse.

1) ie every company i've ever worked for. Didn't stop the last one from installing stuff that wasn't ready (and not telling the customer it was half-finished). Glad i'm not there any more, i was Lead Engineer, Maintenance, so i'd have been the one to clean up their messes...

2) actually, i think the earthquake gave them a good excuse. They probably wouldn't have delivered the Big Whites and Fisheye Zoom until now, even without the earthquake, but now everyone's complaining less because they think the earthquake is more to blame than their (slow development and/or optimistic marketing).

EOS Bodies / Re: 1Ds Mark III Has Left Canada
« on: July 24, 2011, 08:25:36 AM »
Canon Australia still list it on the front page of their camera section, 550D and 1000D are still there too, otherwise there's only one model-per-line.
Let it never be said that Australia gets tech first, or cheap, or even ever sometimes though.

Last time I personally saw a 1Ds3 in a shop or online, it was in Vienna mid-2008, most online shops don't have it in stock, or even in their stock list anymore that i've seen (mostly dutch and australian shops).

Lenses / Re: why????
« on: July 24, 2011, 07:40:24 AM »
given yields also fall exponentially with die size, my guess is a full-frame chip will always be about 3 times as expensive as an APS-C chip

I can't find the link, but i read very recently that a FF sensor actually costs 20x an APS-C sensor because of the yield and possibility of defects...

As for the OP, i've always wondered why they can't do a smaller f/2.0 zoom, even a f/2.0-3.5 variable-aperture zoom would be nice (i think sigma did this, but it went 'slow' fairly early in the zoom range).

But the marketing department obviously has strong opinions or reasons, canon are among the last hold-outs not producing an APS-C prime lens yet.
Their thinking is probably going along the lines of only producing/updating L-primes for FF, we APS-C users haven't spent enough on a camera so we don't care 'that' much about IQ, so we're content with our current range (efs 10-22, 17-55/2.8, and 15-85 being the only standout-IQ designs in the efs range, still nothing's sealed).
(and the sooner they realise that's BS the better for all of us, the more people shout in places like this the sooner it might come, we can only hope :) )

Canon General / Re: hello, and another request for suggestions
« on: July 24, 2011, 07:28:53 AM »
I'd always thought the 60D was sealed, just not as good
(i've seen the quotes a lot 1D/s>7D>5D>60D in levels of sealing).

ok, i've just found at Canon UK, the footnote at the bottom says:
"Water/ Dust Resistance Yes¹"
"Water/ Dust Resistance ¹Memory card and battery door only"

So yeah, it's not the best, but it's better than nothing. Sealed L Lenses will help a bit, i wouldn't be taking it out in downpours in any case though.

And owning a 7D+15-85, i wouldn't be running with that. not even with a 100g niftyfifty attached. I probably wouldn't even try with anything bigger than 1000D+50/1.8 (but then, that's me, i wouldn't make a mini-marathon carrying nothing, let alone camera). Giving it to family (watching on the sidelines) would be an idea, if it rains they can always stick it under an umbrella...

as for the plane, any camera would be good, i'd be more springing for a good IS lens. i'd be not recommending the 15-85 for this, unless you can use 2 hands: after 6 months mine has decided its zoom-ring is not enough to stop it creeping out or in when it's held vertically (i'll presume you're taking shots straight downwards). Too bad there's no good IS-enabled wide-primes for that job...

Overall, the 7D is a lot more camera than the 60D, especially for the AF and FPS speed, AF microadjust is a very good feature too. But for 6-year old lenses, you'll be held back a bit by slow AF motors (what are your other lenses btw?).
Hanging a camera out the side of a plane, pointing downwards, would be a very good use for the twisty-screen though (unless you take through a perpsex floor, or hang your head out to focus too?)

Lenses / Re: Using EF-S lens on FF body???
« on: July 24, 2011, 05:43:49 AM »
This may be my interpretation only (so don't wreck your camera trying, please), only Canon-brand EF-S lenses protrude deeper into the body than EF lenses.
3rd-party brands have a smaller image circle, definitely, but they don't protrude any deeper than an EF lens?

When you think about it, only canon have the dedicated shorter-mount, no other camera does. If you build a lens for a Nikon, Canon, Pentax, Olympus body, and sell it with different mounts and electrical contacts only, you make the lens fittable to the longest mount (generally Nikon F) and don't change the optical formula for the other brands. Even Nikon DX lenses fit FX bodies (i think) without breaking a FF mirror.

So I would not be surprised if any 3rd-party aps-c only lens fits a 5d/1d/s (as long as it's not a canon-specific non-canon-brand lens).

But i would still be very careful, mirror-lockup/liveview can turn itself off at any time, as noted (i always forget to change the time-out on my camera when manual-focussing with liveview, until the screen goes black and mirror flaps down, then i remember)

Canon General / Re: What?? A SCAM INVOLVING A CANON T3i??
« on: July 24, 2011, 05:30:03 AM »
I've never had any dealing with craigslist, being an aussie, but i've seen a few on ebay (which does pride itself on having cleaned up a lot of scams compared to when it started).

i saw an EF 14/2.8 going for cheap, starting at $1 auction, and put it on my watchlist. I would have bid on it, but the seller was in Thailand, with a 0 feedback rating (auction was in aussie dollars, and listed on ebay.com.au). It finished around $1400 (c.f. B&H new price $2300), and I kept it in my watch list. Whoever the buyer was, they never left positive feedback to the seller, not sure if they received it or not. Either way, after a few months, the seller was listed as 'no longer a registered user'. I know ebay say you're protected, but generally only $400, and with fees and whatnot you never get back the full amount.

Same thing recently, a Zeiss T* 35/2 went for $757, to a seller from china with 0 rating. I was planning to watch the item again for a few months to see if it had a happy ending, but it seems not already, the seller is -1 feedback with the comment "This seller sold the item through another netshop the day after I won the bid". So at the least it looks like this buyer didn't lose any money.
It's a bit similar to the craglist scam though, could have easily turned into a "but i've got another lens i can sell you...".

long story short, always check feedback from sellers, especially if you're handing over a lot of cash (only pay $1-2 max for every positive feedback they've got is my rule).
and if it's too good to be true, it normally is...
