Pricewatch Deals / Re: Samyang 24mm f/3.5 ED Tilt-Shift in Stock
« on: May 06, 2013, 01:41:36 PM »
This lens definitely has interested me. Glad to see it's at least fairly decent, resolution-wise, to the Canon 24 T-S. I'd hoped it would be a bit closer, especially at the larger apertures. If the other reviews on the Tilt and Shift functionality are positive, I think I'll be looking to add this to my lens collection at some point in time, maybe after it's been in the wild long enough that the price might come down a bit.

If I photograph a group of friends smiling and holding up their index and middle fingers, while sitting behind the cracked windshield of a blue, 1950's T-Bird that they've just washed, does that count for 9 or 10 of the photographs?!?   ::)
I'll give you 9.  I don't think it would count for the cooking utinsel.

the hood could be open with someone cooking an egg on the engine

Actually, I was thinking the T-Bird would pass for "An interesting structure."  If not, then I'll just shoot it front of Stonehenge!  Oh, and I have to make sure the chrome bumper is polished.  Then, I'll throw a potted plant next to the car, while one guy holds a spatula and another brushes his teeth, and I think I've got it all covered!   ;D

Wish that'd work, it's pretty creative, but according to the rules:

...and must contain 14 images as they relate to all 14 clues (images may be ordered in any way).

No lens (at least today) comes with a UV filter, you need to buy them yourselves. As for the super telephoto lenses, they do, it's just a filter that's dropped in close to the lens mount rather than all the way on the front of the lens like smaller lenses. I shudder to think of the cost for a filter that size.

Is the camera going to sleep? Check your settings, I'd bet that you have the auto-off or auto-lcd off set to just a minute or two.

Lighting / Re: Speedlite Remote Trigger Question
« on: April 25, 2013, 07:05:14 PM »
Using the YN-622's you don't have any of the speedlites being 'master', that's what the Yongnuo triggers are for. You stick the transmitter on your hotshoe, and the receiver on the bottom of the speedlite and you have you're wireless RF TTL.

In order to get TTL you'd need a possibly very long cable, if it'd even work due to there likely being a max length for ETTL cable. Using PC-Sync triggering you have a very, very long max length, but you lose any TTL/remote setting and you need to make all the changes on the speedlite itself.

Hopefully all of that made sense. So short answer is, you don't need to worry about master/slave with that kind of wireless TTL system, however there are certain limitations. However they're a great deal, and I've heard nothing but good things, and if you eventually hit their limitations you'll work around them or there will be a new version that's fixed it or you'll just have to fork over for pocket wizards.

Portrait / Re: Need advice, what can I do to improve?

Was the off camera flash below the model? I think since these seem to be going for a natural look you need to balance the ambient light with the off camera flash and the reflector better- Ie: A lot of the shadows on her face (especially shadows cast by nose) are going UP! This just looks odd and isn't flattering on an otherwise beautiful face.

I'd suggest raising the light source higher so the shadows fall more naturally.

OP was using a reflector, not a flash. Although you're point about being careful about the shadows on the face is a good one, and just as relevant with any lighting setup.

I'll put in another looks pretty good. I'd say you used your reflector(s) well, although I think the other 2 posters have some good comments. While the model is pretty, there's just something in the composition, or the way she's holding herself, or something so that the images generally aren't grabbing me, even though they otherwise are reasonably good. Sorry I can't zero in on it a bit more for you.

Third Party Manufacturers / Re: Zeiss 135mm f2 Apo Sonnar Preview
« on: April 22, 2013, 07:54:22 PM »
Looks to be a great lens, but it still has no AF, weighs a lot (2.02 lb), and costs double the current 135L price  :'(

So it'll cost as much as the next Canon 135L then? Joking, I kid. I kid. No really.

Joking aside, I'd love to get some Zeiss glass, but just too expensive for me and for what I normally do. So, perhaps some day...

Canon cameras contain information about all the EF lenses and the commands to send to them.  Third party lenses tell the camera that they are a Canon lens and then translate the command they receive to their lens.  This can cause even another step that adds to inaccuracy, but it can be adjusted by AFMA as well.
Its a lot more complex that a person might think.

Again, all of that would be solved by closing the loop. Then all you'd need is a correction for sensor/vs AF array, which would be body specific and programmed by Canon at the factory.

It is sounding like the whole phase detect AF system is fully open loop, which really surprised me. Is Nikon like this too? Do they also have an AFMA type feature on their bodies?

Wish there were a Canon engineer I could speak to this about, would be a fascinating discussion!

Even with a closed loop, you may not be able to guarantee that it will always be correct since there's long term wear and tear, if the body is sent back to be cleaned and things shift slightly...plus it'll be different if you're using it in cold weather vs hot weather since parts expand/contract and at different amounts.

If it was closed loop, with a second look, we would be only a few steps away from a self-learning AFMA built in into the camera. Now that would be nice, wouldn't it.
More than nice ... it'd be AWESOME!

The problem is you can't really, unless you also look at the actual image projected onto the sensor. AFMA fixes the situation where the AF detects "in focus", while due to small differences between lens + body combinations, the image projected onto the sensor is not quite in focus. So if the lens mount on the body is every so slightly thicker than the specs but still within tolerances, and the sensor is positioned ever so slightly closer to the back, then while the AF might be in focus, what is projected onto the sensor is just slightly off leading to images that might be a bit software than the might otherwise be. This is most obvious when you have a very shallow DoF, because the plane of focus is very thin where being slightly off from the focus is noticeable.

You say your monitor is uncalibrated? And then you export as JPG to sRGB I'm guessing? Is your image viewing application color aware? Sometimes when shifting between color spaces and your viewing application doesn't have any concept of color space, the viewed image can be off from what it really is.

Lenses / Re: 24-70mm upgrade?
« on: April 17, 2013, 12:30:05 AM »
I've rented the Tamron 24-70 a few times now (still saving up for it) as needed, and it's quite a good lens. AF can sometimes be a touch slower to get going than most of the rest of the L lenses I have, but in general it's quite good. Heavy though, but so is the Canon 24-70 v2.

Software & Accessories / Re: Adobe Lightroom 5 Public Beta Available
« on: April 16, 2013, 02:51:48 PM »
It's slow going due to general buggy-ness

My experience when trying it is quite the opposite: LR5 feels like turbo-charged, as if the build a wait loop into LR4 to make people wish for an upgrade :-> ... this and some new features like the heal/clone brush are enough to upgrade, let's hope the RC phase doesn't take the better of a year's time.

Out of curiosity: OSX or Windows? I've thus far only used it on Windows 7. May load it up on my Mountain Lion machine this evening.

It does feel peppier than 4, and I'll note that I always work each photoshoot in its own fresh catalog, so there's no "few hundred versus tens-of-thousands" effect at play.

What I meant was: getting through the entire set is slow going, because I have to restart LR every couple of frames. Most common failure has been the adjustment brush. It repeatedly stopped working, i.e. I'd select the tool but when I clicked to place it it merely zoomed in an out. Restarting the software remedied it. Other times it crashed outright.

Ouch, that sounds quite buggy. If I keep hearing this, I might wait for the next beta or RC before trying it out.

Lenses / Re: EF 200-400 f/4L IS 1.4x Availability

So over 8 lbs? Yikes. :o

Holy cow, not that I'd be in the market for a 10k lens, but I'm wondering what users Canon has in mind - at this weight, most photo-journalistic or quick action shots seem to be impossible?

But probably it's really a small pro sports (and maybe wildlife?) market, and those few people are fine to shell out that money for top notch iq & reach flexibility.

Until you put it on a monopod/tripod and shoot from the side of a major sports event or out stalking wildlife. Or you're a paparazzi and needs to be able to go from shouting "Hi there" to being so far away as to be unnoticeable.

EOS Bodies - For Stills / Re: Confusion about Macro Photography

The definition I've heard is when your subject is reproduced on your recording medium (film or digital sensor) near or at 1:1 or better. So if your subject is 5mm long, it's near or at 5mm long on your recording medium. Or possibly more, so if it's 2:1 magnification, it's 10mm long instead of 5mm.
