Lenses / Re: Sigma 24-70 f/2 OS HSM Coming? [CR1]

but the idea that an equivalent telephoto f/2 lens for the same relatively bargain price does not seem feasible.

"Feasibility" in this case is relative to supply/production cost (no one knows for sure) but also demand, and looking at all the drooling CR members in this thread Sigma would be Nikon-crazy to sell something unique like this for anything less than $3000 if the iq & af is really good.

The cameras meter still suffers from the 18%-problem

Um, would you please enlighten simple /me about the 18% problem, obviously it's about the grey card density, what of what are talking specifically (link, keywords to google...)? Maybe this?

As promised... here's an hdr image I took while in Colonial Williamsburg... it isn't anything special, but the clouds maintained their detail as well as the subject.

Imho that's a nice one and is how I'd expect good hdr to be, it impvoves the mood w/o too much tonal range compression - though the postcard colors doesn't really improve the "natural" feel, ymmv of course :-p

I love using HDR...but beauty is in the eye of the beholder....always.

The real question/issue is: What is HDR?

The Wikipedia definition that hdr is when you've maxed out your digital imaging's dr for one shot is moronic for image evaluation purposes because in this case the same shot can be hdr or not!

For me, hdr is when your mind tells you (subjectively) that this whole scene is something you'd never be able to see with your own bare eyes. but you'd have to look at specific parts and let your eyes/mind adjust. You can get this effect from merging shots and tonemapping, or from a single shot by too much pp, esp. raising the shadows too much. If this results in a plastic/artificial/cgi look I'm not a big fan anymore, and the links above look like software rendered images, nice shots though.

I personally like hdr a lot for night scenes and for gently getting around blown highlights though (windows to the outside, the sun). And I know people who didn't do as much hdr as I did go "wow!" looking at an old school hdr shot when I go "Harrrrggnnnn" :-p

The one thing I really like about the Canon gel holder is that it keeps the gel away from direct contact with the head, I have found most gels have very short lifespans when they are attached

That's pretty interesting, I never thought of it but as far as I know you're speaking from a good deal of experience - anyone else experienced this issue with velcroed gels vs. a gel holder? Thx.

Lighting / Re: 3rd Party Flashes vs. Canon's...
« on: July 30, 2013, 10:58:10 PM »
I feel is another flash...a stronger flash!  I currently have only the 430 EX II.  I've been looking at the refurbished Canon 600 EX-RT offered by the Canon store for $440, but it's out of stock.  I'm also looking at the YN 568 EX II.  Any of you have any positive experiences with 3rd party flashes?

I just read a lot of reviews about the Yongnuos, and then bought a 2nd 600ex-rt, for a hilarious amount of money I might add. If you come from a 430ex2 (I've got one, too) the yn568ex2 should be more than fine, esp. considering the price, but it has some drawbacks:

* No built-in radio control, you need a dedicated trigger which adds bulk you might not want. So if you want 3rd party, you should think about waiting for the next Yongnuo speetlite w/ built-in radio, their manual flash already has it. Optical control is a big hassle, indoors it might work, outdoors it's a nightmare.

* The 600ex-rt has a 200mm reflector which is extremely helpful for outdoor tele flashing, and of course the Canon has tons of other nice features like linked shot & group mode (read the respective reviews on that) while the 3rd party copies more or less imitate the 580ex2.

* The display & usability of the 600rt is absolutely terrific esp. when changing settings in a hurry, so the question is: What do you intend to shoot with the flashes?

Btw: pro Yongnuos radio trigger: They have remote 2nd curtain sync, take that, Canon...

Last not least: great site on flashes, no ad intended:

+1 for flash in M mode. AV-TV is dead weight when you need to control ambient/flash exposure.

It is, could you elaborate? You control ambient via ec, imho Av is very handy when lighting changes on every other shot, esp. if you're able to select a min. shutter speed (newer cameras or Magic Lantern).

but I will say that Av is much more effective on recent bodies where you can specify a minimum shutter speed

Did I mention Magic Lantern does this for the rest of us ("ML Auto ISO"), providing the level of control like the newer and expensive cameras (min/max iso, min. shutter in av, min. aperture in tv, ec on m) ... but you wouldn't know about programming your camera, would you, mr. 1dx :-p ?

For all the M mode fanatics: The newest ml builds have a "autoexpo function", you can define your own aperture curve and then some, imho this a terrific feature:

Lighting / Which gel holder for the 600ex-rt - original or 3rd party?
« on: July 30, 2013, 10:01:27 PM »
I'd like to buy effect and color correction gels for my 600ex-rt flashes, and there are decent offers from the UK cut for the original Canon gel holder - see

However, I'm not so sure if the Canon gel holder is really the way to go, and the flash afaik won't recognize 3rd party gels anyway so there's no need for large gels that cover the sensor... Questions:

* Do you use the Canon gel holder with the 600ex-rt or did you buy other holders (which) that take other/smaller gels (which?)?

* Do you use a plastic gel holder at all or simply velcro-strap the gels to the flash (with the added advantage that this method works on all other flash types, too)?

Thanks! I already suspected you have tried about every piece of photography equipment ever invented, and after a trip to the surprisingly clueless sales people in my local photography shop today I have to say I value your help more than ever!

1. I think that RT flash control will be incorporated in the 7DmkII (not just 'hoping').

Ok, now I'm really keen to see if I was too doubtful of Canon (who? me?) :->

Another website did extensive testing of 7D's AF accuracy / consistency

Imho more precison/consistency in the 7d2 is a must, I know the lensrentals reviews, and they write the 6d/5d2 af type doesn't use the enhanced precision of Canon's latest lenses like the 70-300L and 24-70L2, so to boost sales and torpedo 3rd party manufacturers it's likely Canon will do something about it.

4. Swivel screen - I enjoy macro photography a lot, and an articulated screen can be invaluable here, especially when taking photos at ground level.

I see some people going ballistic, and I don't want to raise my struggle with buying the 6d again, but if I do I will *curse* Canon every single time I lie flat in the cold and wet mud in late autumn when doing macros of mushrooms... this is really an issue for me, I surprised so many people don't see the swivel screen as a useful feature.

Lighting / Which coldshoe for 600ex-rt type (sealed hotshoe) flashes?
« on: July 30, 2013, 09:06:31 PM »
I'm very good at loosing small plastic parts, so I'd like to stock up on some coldshoes for my flashes. I've already tried to order one version, but it doesn't really fit because the rubber part on the hotshoe gets crammed inside the coldshoe, there is no lock and the flash tends to fall off (picture of this version attached, it's the black gadget). Before I waste money on other overpriced plastic pieces:

* Did you find any type of 3rd party coldshoe for putting on the ground that is equivalent to what Canon delivers (no, thanks, I'm not buying an original Canon part for this :-p)?

* I also need a foolproof coldshoe just to attach the flash to a bracket or tripod, something like the blue thing in the attached picture, but I'd be ok if it was cheaper than this patented version...

Thanks for any help, I cannot predict how these ebay offers really fit and I'm not willing to pay €20 in a local camera store for e 2 ct plastic piece, call it principle if you like :-o

I could not live any more without building my own machine to the specs I need, so there is no weak link in my desktop.
I agree, it's easier to build a PC exactly to your needs and, is easy and cost effective to upgrade as technology changes.

-1 ... because today's pcs are built out of fewer components (many things are on the cpu die for example), there is very little to customize in a standard setup that *really* makes a difference - which is why so many oem are going out of business, they've simply lost their selling points.

On the other hands buying a complete pc ensures you support (fewer points to argue over who has done what wrong) and people who do this for a living imho simply are better at building a clean machine with proper cabling than me doing it every so many years. Plus many oems get very competitive bulk prices for their components which I find very hard to match even when buying at the cheapest discount/online shops I know.

It might make a difference for hardcore gaming and ultra-high end setups, but for your general lightroom/ps editing personally I'm leaning towards buying a complete desktop once I feel the need for more speed than my current crappy laptop can deliver.

Excellent cameras still. Glad that support is still excellent. Peace of mind.

It's also the other way around: They are excellent cameras *because* they are still supported!

Unfortunately for us Joe Sixpacks it's not like that - and even for 1d it could be a lot better: think Canon would add rt (and group mode) control to the firmware of the *current* cameras like 7d & 60d or the *last* generation of multi-thousand $$$ 1d? No way, even if it'd probably just take their programmers some days to do it :-(

Hrm, good question! My CR2 are in one folder, I do an import manually dropping them there, then use "synchronize".

Imho not a smart idea, Windows filesystems hate folders with a lot of files (only the newest Linux/unix fs are better here). How many files are in there? Simply do an experiment: Copy some cr2 into another folder, create a new catalog, add them nr/sharpness to zero - better that way?

What I can't wrap my head around is why it doesn't render the images very fast/ahead of time.  I tried the following:
1) Just letting it sit there for an hour, so it pre-renders, say, 100 photos

100 cr2 in an hour? That's pretty crappy, even by my standards (dual core 2ghz laptop). With 20mb/cr2 this cannot be a disk bottleneck, but rather sounds maxed out cpu or memory. Look at taskmanager, enable the relevant columns (cpu usage, cpu time, peak working set, max commit size) and find out.

I bet we'll see RT master in the 7DII...

I'll bookmark this and remind you :-p ... I'm sure Canon will add rt master capability sometime, but I bet this won't be the sports/high-fps 7d2 (can your flash do 10fps?) but the 5d4 or the next high-mp premium 1d.

Think of the profit they make: the st-e3 controller sells for ~€300, but most likely consists of parts that you can buy for less than €30 in the electronics discount shop next door :-o
