Canon General / Re: DxO: 650D sensor not as good as 600D...
« on: October 11, 2012, 07:58:07 AM »


Yes, I noticed the same thing, I guess it could be within the realm of testing error variation, and not an actual difference in performance. If only they would produce a 700D with all the features of the 650D, but improved low light performance (i.e. a new sensor), I'd buy it straight away.

Video & Movie / Re: 1DC vs C300/C500 for pro video
« on: October 11, 2012, 07:54:29 AM »
Question : I am mostly ignorant about video matters, can someone explain the interest of a 1DC camera versus a C300/C500 dedicated video camera?

 No irony here, just an honest question, I don't understand the advantage of a DSLR for pro video.

Without thinking too deeply, 2 obvious advantages:

1. It's a fantastic stills camera as well (effectively a 1Dx)
2. Full frame sensor would be an advantage if you want very shallow DoF, and it will work well with EF lenses

On the other hand, the C100/300/500 have XLR ports etc, making them much better for audio

I had a quick go at it with aperture. Needed straightening BTW.

NO, the big files don't slow things down (unless you have a shitty computer or you're a sports photographer)


That's just silly, as somebody who processes thousands of images per weak, I can assure you, image size makes a big difference, and if you don't need more than about 20MP, double that is a waste.

EOS Bodies / Re: Why are flash sync shutter speeds getting worse?
« on: September 24, 2012, 02:59:44 PM »
You guys do realize your complaining about 1/20th of a second difference between the D600 and 6D, right? That is 0.0005 seconds difference! It really doesn't matter that much, and given the design of the 6D as a low-light camera capable of ISO 25600 and AF at EV -3, it matters even less. You could bump up the ISO by a third of a stop for pretty much ANY exposure and compensate for the difference if you really, really needed to. Now, if it was a 1/60th sync speed vs. a 1/200th sync speed, that would matter, but thats not the case.

please stop talking about things you don´t understand!!

ISO affects FLASH and AMBIENT exposure.. it´s obvious you don´t know what strobist are talking about.

yes 1/200s was already bad... doesn´t change a thing that the trend to make it even worse is a bad sign.

I think jrista makes a fair point.  I agree that 1/200 s X-sync isn't good, and 1/180 s is worse.  But the difference is only 1/6-stop. 

OTOH, despite the ISO improvement in recent sensors which would allow you to more than make up that 1/6-stop in terms of noise performance, that's not going to help stop action. That 1/6-stop is well and truly gone.

Aye. I don't disagree that 1/200th isn't great, and neither is 1/250th. But since none of the entry-level full-frame cameras have a 1/500th second sync speed, it doesn't make much sense to complain about a sixth of a stop worth of difference. I wasn't thinking that bumping ISO would help stop action...the flash pulse is for that. I was only thinking if you wanted to compensate for the loss of exposure, you could easily bump ISO without worry on a camera capable of native ISO 25600.

That 1/6th of a stop manifests itself to the budget strobist in the form of additional power required of the strobe itself, to compensate for the smaller aperture necessary to properly expose the background on account of the slower shutter speed. Thats why strobists like high sync speeds and are often found complaining about little things like fractions of a stop. 

no its not much, but it will eat more batteries, affect re-cycle time, etc and is  more relevant to those using small speedlites, especially outdoors, as upposed to those packing around larger strobes and battery packs on location.

I think your missing my point. Instead of narrowing aperture and reducing shutter speed to compensate for ambient exposure...couldn't you keep flash power, aperture, and shutter the same and boost ISO? That was what Canon-F1 was freaking out about...increasing ISO affects BOTH flash and shutter speed. Keep flash power the same (or reduce it), use the same shutter and aperture, and bump ISO. Does that not solve the problem? Or is everyone here still thinking that high ISO is evil because it introduces noise...which would not be exactly true with the new cameras from Canon.

You are totally mixed up in your thinking. The scenario here is bright sunlight, ISO 100. Shutter set to max sync speed and aperture set to expose background as desired. Boosting the ISO does absolutely nothing to help this situation, quite the oposite.

Why downgrade?

Now, how this is a downgrade? explain!!

Tongue was in cheek, but how about flash sync speed for one.
Hardly a issue for a Rebel User who does not even own a flash.

In that case, I would suggest getting a flash, before upgrading the camera.

Hmm, just wondering, do other new cameras such as the 650D have compatibility with the radio flashes, or is it just the 1Dx and 5D3?

I think these shots just look good because the subjects are attractive people. I doubt any diffuser was used.

EOS Bodies / Re: Canon EOS 6D Announcement Soon? [CR1]
« on: September 08, 2012, 07:10:17 AM »
I have spoken to a few friends who own the 5D3 and while it is a wonderful camera, they are still torn between it and the 5D2. Like most cameras, even though the 5D3 was meant to be a replacement/upgrade to the 5D2, there are still some things the 5D2 does better, or just as well.

If the 6D does come out and it has a lower build quality than the 5D3, I would say stick with the 5D2. They are going to continue to drop in price new and used. I love my 5D2, it takes amazing photos. Honestly, the $3400 for the 5D3 is keeping me from "upgrading". That's way more money than I want to spend considering I have a 21mp FF camera at the ready. It will be interesting to see what Canon considers as a "replacement" for the 5D2. I still believe an affordable FF body is needed and the 5D2 could use some upgrades, but will the upgrades be worth the price if you already have a 5D2???


Not to get off topic, but I owned the 5D Mark II and now have a 5D Mark III.  Excactly what does the 5D2 do better?  I cannot possibly think of ONE thing it does better.

I've heard people say that the 5D2 centre AF point is better than the one on the 5D3, and that the AF works better in low light on the 5D2. Not tried a 5D3 yet myself, so only going on what I heard.

In general, it seems like the new AF system is a lot more complex, and you need to really understand it to get the best results, where as the 5D2 system is pretty straight forward and perfectly capable for wedding photography etc.

Also, the 5D3 sensor is hardly a huge leap forward (in terms of RAW high ISO performance), so there's not a huge benefit in upgrading unless you require the FPS upgrade or the extra AF points.

Let me put it this way, it's a costly upgrade, and as a pro, it can only be justified if it's going to improve my work significantly, which I don't think it will. The new radio flashes seem like a much more useful upgrade TBH.

Lighting / Re: Buying a Canon Speedlite 430 EX II - Advice Needed
« on: September 02, 2012, 07:07:08 AM »
Just in case you missed the thread on batteries for 600EX-RT:

For full-on extended projects I don't leave home without an external battery pack, a Quantum Turbo T3 with the twin outputs. The extra oomph is indispensable for prolonged bounce flash situations or when calling on speedy recycling with HSS. The 430EX and one can safely assume the 430EXII are terrific value and great performers. But they lack the option of plugging into external power.

For the same money you'd get a mint pre-owned 580EXII which delivers a bit more output plus has that valuable option of plugging into an external powerpack. With the 600EX-RT selling so strongly there are good numbers of 580's popping up on Gumtree, Craigslist or eBay. Speedlights are pretty robust creatures so I'd have no hesitation getting a good condition pre-owned 580.


580EXII flashes do go wrong (so there is a risk in getting a second hand one), and in my experience the 430EX and 430EXII are more reliable. Because the flash is less powerful, it does not put such a strain on the batteries, nor does it overheat so easily.

Adding a power pack to the 580 series flashes does help the recycle time, but increases the risk of overheating which can damage the flash.

On the other hand, a RT version of the 430 series flashes must surely be in the pipeline.

Lenses / Re: Canon 28 1.8
« on: July 16, 2012, 06:31:29 AM »
The real question is this: Why has Canon left crop users in the cold by not releasing a "normal" prime in an ef-s mount?  Buying an ef 24, 28, or 35mm lens to substitute a "normal" on a crop body is stupid.  You'll have a close to normal focal length, but you'll have a wide angle perspective.


 Your concept of perspective is flawed I'm afraid. A 30mm EF lens would have exactly the same perspective as a 30mm EF-S lens if they were both mounted on crop sensor cameras.

Third Party Manufacturers / Re: So Nikon D600 is real after all
« on: June 14, 2012, 05:22:02 AM »
Does look pretty sweet, its even got a top panel LCD. Reading the spec list, it's also meant to have weather sealing!? How are they pulling it off? obviously it won't be top notch weather sealing, maybe a bit behind or equal to a 7D but the whole package is looking very appealing to me as I'v wanted FF for ages and was going to settle on a 5Dmkii and put up with the AF. Hmmmmmm...... I could deal with shooting Nikon and Canon.

I doubt weather sealing costs more than a few pennies to add, unless it's 'drop it in the bath and it's ok' weather sealing.

And the rumoured prices always seem to be miles off, so I wouldn't pay much attention to that. If it's a new sensor it will put a lot of pressure on the 5D3 price, if it's the old D3x sensor, not so much!

The really good news is that the retina display will surely be applied through the entire range over the next year or two, I'd like a 27" iMac with Retina (with 2 internal drives as well if possible).
