EOS Bodies - For Stills / Re: f/22 and diffraction

« on: March 11, 2013, 09:53:16 AM »

Bryan wrote that book at a time when digital imaging was still in its nascent stages. Film SLRs were impacted by diffraction but it was not easy to spot the degradation in IQ because film ... was film. It was not possible to pixel peep the images the way you can do with your DSLR's images at 100%, 200% or 400%.
 
Though the theory says that over f/11 your images will be hit by diffraction in a DSLR, usually the difference will be negligible upto f/16.

BTW, diffraction impacts APS-C and FF sensors differently with APS-C's being less tolerant because of their higher MPs on smaller sensors.

Lenses / Re: Bridge not sharp - why?

« on: March 11, 2013, 09:19:09 AM »

I agree, it may be the AF.  This may sound stupid as you have probably already tried this, but I would set the lens to MF, then use live mode with largest magnification and then adjust the focus until pin sharp.  Then switch out of live view and take the photo. 

Why not take the shot in live-view itself? It has the added advantage of avoiding the mirror slap.

Lenses / Re: EF70-200 f/2.8L IS ll refurbished @ Canon for $1699.20 & I'm screwed

« on: March 10, 2013, 12:50:17 PM »

Granted I don't have this lens, but Canon list this lens at Weight 52.6 oz./1490g  or 1490 Grams = 3.284887703800 Pounds. What is so bad about that?

I've walked around for hours with a 300mm f2.8, taking pictures of wildlife @ 5.6 lbs and granted it was a workout, but still...

Carrying a single lens is not such a big issue ... but try doing a trek ascending 4,000-5,000 feet with a few lenses, multiple camera bodies, a tripod and some other stuff you need. Weight does become an issue at some point and its better to be light rather than heavy! OTOH, maybe you are stronger than I am

Thanks for the replies people. I've ordered the Giga Pro. Will consider getting the Camranger once they start shipping to India.

If weight is not an issue, you should sell the f/4 lens.

I plan to get the f/2.8 II but will retain the f/4 (non-IS) to have a lightweight tele-zoom to take on hikes. The 2.8 is a beast but weighs twice as much as the f/4 lenses. Having two zooms in the same range seems stupid but them again ... Horses for courses!

Technical Support / Can switch orientation on my laptop!

« on: March 10, 2013, 10:47:56 AM »

Hi Guys,

I can't change the orientation of my laptop from landscape to portrait. The CTRL+ALT+Arrow key combination does not work.

I've also tried the 'screen resolution' after right clicking on my desktop. There is no option for flipping the orientation.

Has anyone else faced a similar problems. How do I change the orientation.

FWIW, The display adapters in the Device Manager are listed as:

1) Intel(R) HD Graphics 3000
2) NVIDIA GeForce GT 630M

EOS Bodies - For Stills / Re: Sell canon 5d3 and return new macbook pro retina to buy the 1d x

« on: March 10, 2013, 09:19:15 AM »

I have always wanted the 1d x but am unsure the extra $3k is worth it for me. The pro's for me are better iso in low light and af point metering. Cons size and could that money get me a nice 35 mm prime and maybe a 1.4iii teleconverter and keep my macbook. Just stuck on the decision. Any suggestions?

I was glad you kept your gear - http://www.canonrumors.com/forum/index.php?topic=12123.msg215823#msg215823 - but if you were thinking your current gear was tough to lug around, the 1dx will make it even tougher.

Don't you like the 5d3? If not, by all means get the 1DX, OTW it may be better to get a couple of super-fast primes.

IMHO based on what you say you shoot, it is likely that spending an additional $3,000 will lead to more remorse than satisfaction. Don't do it!

Compose the shot yourself and get the AF off the shutter button and only on the back focus button. That way you can ensure that the focus will not change when someone else handles the camera.

Additionally, you could set up a custom setting of a fast shutter speed, reasonable aperture ... Say f/6.3 and auto ISO.

EOS Bodies - For Stills / Re: Mark III manual mode-changing ISO speed, its not changing the exposure meter bar

« on: March 08, 2013, 01:46:16 AM »

When I click the ISO button, mine is just locked in the middle. So I have to adjust ISO seperately,

I'm confused, are you saying you are shooting in Manual mode and changing the ISO does not change the exposure you see in the viewfinder?

Not to be an ass (ok probably) but didn't you just ask the same question

Not really. I was guessing that the OP might NOT be in full manual "M" mode which would explain what was happening so was just confirming.

He mentions "manual" but it is again unclear whether he is talking about full manual camera control or simply changing the ISO manually.

There we go ... 5 replies simply trying to understand the question.

« on: March 08, 2013, 01:04:41 AM »

The OP specifically states he is pressing the shutter to see where the meter is after exposure

I think I understand what you are saying. Essentially when looking through the viewfinder and changing exposure whether it be shutter, aperture, or iso you aren't seeing real time metering difference on the metering bar in the viewfinder?  As such you need to half press the shutter to see the metering difference?

Technical Support / Re: im thinking about buying a DELL 2713HM - how important is wide gamut?

« on: March 07, 2013, 09:23:58 PM »

STAY AWAY FROM DELL.

Worst Monitors I have owned.  I am going on my 4th monitor in 5 months because of dead/dying pixels and other issues. 

Specs are nice - but product is crap.  Your luck may vary, but I don't even bother putting the box in the attic any more... I just leave it right besides the desk. 

Maybe Dell can offer a new service and include a future dated RMA with every purchase.

Sounds like you have been buying the Dell office grade cheapies. They're patently not suitable for working with images or performance gaming. In a recent similar CR thread I mentioned we have five Dells in the studio, U3011, U2711 and three older UltraSharp spec 24 inch panels.

They have all been faultless workhorses. I will buy more Dells when required. My first Dell, a 24 inch Ultrasharp from around 2007 is still working perfectly. It calibrates fine with the EyeOne. Very stable. Go figure. People just seem to love flaming Dell. That said, I wouldn't buy anything from them other than their premium monitors. It's not that their other hardware is bad, it's just not suitable.

Thanks pwp!

I had ordered the 2173H on Tuesday and it is on the way to be delivered Monday. I had lost some sleep last night wondering whether it would be a crash and burn for the $ 1,000 I paid for it.

Why did you pay $1000? You could've bought it from from ecost or nextwarehouse (which is where I bought mine), you could've gotten it for $727. With $8 extra, you could also opt for free return shipping if you dont like it. With the money saved, you could've bought the xrite i1 display pro for hardware calibration, which you will eventually need for proper calibration.

I am not in the US and the imports attract a customs duty of 30%.

Lenses / Re: DPReview: Canon EF 24-70 f/2.8L II Review

« on: March 07, 2013, 10:35:07 AM »

More high praise for the 24-70 II, with the usual caveat of price.

Question for people who've bought the 24-70 II and had/have the 24-105mm f/4L IS 'kit lens'.  Did you keep the 24-105L, and if so, now that you have the 24-70/2.8 II, do you use the 24-105L any more?

A few pros I know have retained both. I had put the same question to them and the reason they cite is that for long shoots and weddings, IS is extremely important to them once tiredness sets.

Personally, I'm not too sure of what I would do ... After reading such reviews of the 24-70 II, it feels like its time to try it out.
