EOS Bodies / Re: HELP PLEASE: CANON 5D II - ISO in "M" mode
« on: December 08, 2011, 03:06:33 PM »
ISO min / max limits would be nice as well.
550D lets you choose max-ISO for auto mode, my mum's 6-year-old Pentax *ist lets you choose max-ISO in auto mode, I played with a nikon d3100 for 5 minutes and even that lets you choose min and max in auto-iso mode. 7D probably costs as much as all of those put together, and it can't. Sigh.

Even nicer would be to be able to set +/- EV Comp for when in auto-iso mode, but that's probably 10 lines of code too much to ask...

Agree with your analysis... deserves an applaud.

and now you are balanced at +44/-44   ;D

... Still, a relevant analogy is the use of HDR to increase the dynamic range of current sensors.

Not picking on you John, but Isn't HDR a misnomer? I mean what we are really doing is "reducing" the dynamic range to display on our monitors... in reality it is Dynamic range compression, is it not?

K-amps, don't misunderstand. I wasn't trying to be critical or offend you.

I just wanted to make it clear that Canon charges sales tax because they have to, not because they want to. It's a state and not a federal issue and most states define Nexus very broadly. For example, if Canon has a copier service center in Indiana, or even has an authorized dealer for Canon office products, they have a nexus in the state.

I won't waste space or time with details on this forum, but suffice it to say this has become a major issue between the states and internet retailers.

and I was not trying to "blame" Canon, I just alluded to the choices we have. I am however mad at Canon for not honoring the holiday/ individual discount 9 days after they shipped me the 70-200... they said they could not do it once they shipped the product out.

Amazing pics.... now you guys are making me desire the MP-E65.... sad thing is they dont have it for rental locally... 

Tice the jumping spider shot is amazing... the only way I could do it is set camera at burst mode and hope for the best  :P

i am very happy with my kenko one on all my lenses and testing the 1.4 I found stopping down one more stop from the new wide apperture yields equivelant IQ to the native lens widest apperture ie 70-200 f2.8 put the Tc on at 280mm f5.6 IQ is the same as at 200 f2.8

and it works on all lenses great on the 50 f1.4 to give it a little more reach too

Thanks for your input.

Are they fully automated (AF.metering etc)?  care to post a few pics?

I think another person on this site once pointed out that they like refurbished lenses because they know they've been checked out and brought up to specs individually, while a new lens may get only a cursory once-over on the production line. I don't know if that is true or not, but it makes sense to me.
On another topic:

15% would be an even better bargain if Canon would not slap sales tax on the final invoice value... BH/ Adormama etc are cheaper cause they don't put sales tax on top when shipping to Indiana.

Canon has no choice but to charge sales taxes on their products. Don't blame them. It's the law. Amazon and other sellers can avoid charging sales taxes because they have no physical presence in your state. But, just so you are aware, you probably owe the taxes anyway and while most states don't do a good job of auditing these purchases, that is changing.

I said that; since it made sense to me. I asked Canon about it and they agreed.

On the Tax issue:

I do not think Canon has a tax nexus in Indiana, they have one in IL and WI. I will buy from where ever it seems cheaper to me, if you think I owe taxes, then show me the relevant tax code regarding internet purchases. Does the federal Tax authority think it is ok how Amazon operates, yet holds the individual liable? Shouldnt both be liable or none be?

Neuro... have you stacked the 1.4 + 2x on the 70-200mkii ?

No, I haven't tried that (yet).  I can, if there's interest.  I've been considering doing a comparison set between 70-200 II with single and stacked TCs, 100-400mm with single TCs, and then cropping everything to the same FoV (equivalent to the longest, i.e. 100-400 + 2x), in decent light (unlike the one time I tried the 100-400+2x), and seeing which gives the best results...

I am very curious... if it is decent, I might just splurge on a TC myself...  ;D

Hi Peter:

I had the same issue... Take a look at some tests I did at 100mm (similar set-up as yours) with 2 copies of the 70-200f2.8 mk.ii, I got recently:

I am used to the sharp 70-300L, after all the hype of the 70200f28mkii I too got myself a 70-200mk.II, the tests show it is sharp... but not mindblowingly sharp...,2322.msg49510.html#msg49510

Hope this helps.

 Neuro... have you stacked the 1.4 + 2x on the 70-200mkii ?

Funny thing is last night I was up-rezzing my 5D shot (12.8mp) to print a 24" x 20" for framing.

When I upped the print area (canvas size = 24x20 with smooth gradients algorithm), the issue I saw was not blurring of details, rather ugly noise (Pic was taken at 50 ISO ) : I had to use topaz/Nik define to get rid of the noise then unsharp mask in Photoshop, but it turned out pretty good.  Nik define fixed one noise pattern and Topaz the other. Both work a little differently so modest amounts of both fixed my issue without much loss of detail.

The limitation was not the sharpness/ detail, rather noise artifacts. Assuming 12.8mp was good enough for a 24" x 20" print, I'd say 2mp is enough for 4x6, 3mp for 5x7, and 8-12 mp more than ok for 8x10 prints.

Curious if you use the camera processed jpegs or RAW's from both Cameras? The jpeg rendition of the T2i is better than the older rebels/ xxD's.

I can hear it now!
"And with this 35 megapixel compact body you only have to point it in the general direction of the target and you can later crop down to a 18 megapixel image, just like the 1DX body!!"

Haha made my day, thanks!  ;D

About 6 years ago, the air conditioning on the roof of the building I was working in had a problem with a bearing. It produced a very high pitch noise that I could hear and gave me a headache but nobody else in the office could (I was the youngest...)

Dare I ask what your thoughts are on 96kHz audio? I've got a few SACDs and the appropriate equipment to deliver 192/96 to the amp and out of the speakers...

Exactly! I suspect that if a 5DX were to have a foveon style sensor with colours arranaged vertically rather than in a horizontal 2x2, we'd find companies doing the Sigma thing and calling a camera with 15MP a 45MP camera.

Dilbert: We live in a world where the youth of today embrace the MP3... so 96kHz was pretty much dead on arrival. The beauty of SACD was not only the 96/192kHz sampling, but the ditching of discrete paralell bits and going for a stream of data. It was just a different way of processing data, not merely an upsampled engine that CD used. I too have a few SACD's lying around, they are not bad,  the pricing killed it as well.

Going back to the topic: Looking at apple/ google, buying off companies seems to be the best way to get Patents... however I suspect the fact that the Fovean did not dazzle people like they expected it to may have something to do with it...
