Quest for the perfect copy?

I'm not looking for a perfect copy, but I just want to ask if someone experienced could look attached photo and compare between each corner. I made one (very!) amateur test with my 70-200 lens. For me, it seems like the right side is more blurry then the left one. Opinions? Probably in case of decentering it would be much bigger difference between sides?

Is Dual Pixel Tech Coming to the EOS 5D Mark III?

I wonder why did Canon introduce the EF 40mm STM in 2012 if it had no plans to introduce a FF camera with DPAF shortly after that?
Not quite making the connection there...care to enlighten?

-pw

All the other lenses with STM are EF-S, and work with APS-C bodies that have DPAF.

Why would Canon make a FF lens with STM, if there are no FF body owners to buy it?

Thoughts on repurposing a guinea pig cage as an slr cage?

Jim Saunders said:
The previous poster got to GoPro first, but the cage idea seems sound for working with what you've got. Layers of bubble wrap on the outside might make for a means of damping the impact of a direct hit.

Jim

did I not to mention that the softball players are 10 year old girls don't have a great deal power

I missed it if you did. Your camera to do with as you like, anyway.

What can I expect from CPS's standard "Canon Maintenance Service"

Just renewed for the third year.

I had a 70-200 / 2.8 with impact damage from a fall. They replaced the barrel assembly with the 30% discount and had it back to me 3-4 days after I shipped it; sent back FedEx.

I live in Las Vegas, so CPS has some added advantages for me - they come to various events throughout the year including WPPI, LVMS NASCAR, and NAB. I can take advantage of free cleaning each and every time; and at WPPI they offered limited free printing on a ipf 6450 and Pro-1.

So yes, I am sold on CPS Gold. I am not sure I need CPS Platinum unless one considers it insurance for time-critical situations. Thats why I carry a backup body.

Looking for a Pentax 645N

So, since there's no real buy/sell forum, I'm putting a shout out here that I'm looking to buy a Pentax 645N. Preferably with 120 back & lens. Right now things are a bit pricey on ebay (along with the potential risk) and Keh.com doesn't have really much in the way of bodies & B&H has them, but at even a small premium over Ebay I'm still hoping to find something cheaper. Anyone?

5D M3 - Mirror slap during live view?

Silent mode was going to be my suggestion, but if you are using SM1, that should be like MLU - the shutter only comes down at the end of the shot, the mirror should not move.

Sounds weird to me, I have never had a problem with using LV and silent mode 1, nor does the mirror nor shutter move before the shot is taken.

Either we are missing something or there is a fault.

BTW, if the lens is on AF and even with the shutter button AF disabled, AF can still occur with a wired remote. It does sound just like the camera is trying to AF with 'quick AF' in LV mode. Maybe it is trying even with the lens set to MF?

Whitebalance with grey card seems red?

BlindMan said:
Hello folks,

I recently set my white balance using a new grey card. After that all my pictures seem to have a red tint to them.
I'm using a Canon 600D with Elinchrom flash units and a Mennon grey card.
Before using the grey card i just used a piece of paper for setting white ballance. Seems like i get pretty much identical results with paper and the grey card. - When using the paper I manually added blue in the camera settings to compensate for the red tint. - looks like I have to do the same when using the grey card (somehow makes sense ;) )
When I open the files with the grey card in it and hold my eyedropper on it in photoshop, the color in the card is perfect grey (identical RGB values) - but everything looks reddish???
Just calibrated my screen with no improvement.
Same result on 3 different cameras and different monitors.
Any ideas? Does the background have a red tint or is the balance off?

measuring this picture over here, it does have more red in the RGB, so the background is not neutral,

Tired and Frustrated of the Pocket Wizards

archiea said:
Someone just posted about layoffs at pocket wizards:
http://www.lightingrumours.com/pocketwizard-layoffs-5468#.UwQcOcu9KSM

I had problems with the flex system on my 580exii. Moving to canons 600 changed all that.
I'm not surprised if Pocket Wizard is under pressure. I wouldn't be buying shares in the company.

Remember the nightmare $1000+ Quantum Radio Slaves? What a waste of money they were. Then came Pocket Wizard, full of promise and a high price. Then came the flood of radio poppers all the way from eBay cheapies that mostly work perfectly well to the utterly stable and sophisticated Phottix Odin.

From where I stand, Pocket Wizard is starting to look like the Blackberry of the radio popper universe.

24-70 2.8 L II summary of defects

docsmith said:
I had one lens with a bubble and then different lenses with clicking when I tried to buy this lens last fall. Since I could only vote once, I voted for the bubble....

In past years, it was common for some of the better glasses to have bubbles. Some glasses with highly desirable optical properties couldn't be heated to a high enough temperate to become fully fluid so that bubbles would naturally escape. At one time bubbles were even viewed by some as a mark of quality. Now glass technology has advanced, and sometimes platinum crucibles are used, so bubbles are no more. One or a few small bubbles will have negligible effect on your images.

I think you've been had by a troll.


So I guess your tally is 0.

I almost kept the lens with the bubble. It was great in every other way. The rationale for returning it was pretty simple, 1) shouldn't have a bubble, and 2) I know me, and if I were to ever sell the lens, I'd let any potential buyer know that there was a bubble in the front element, which could kill the resale value. So, I do not regret my action. It had nothing to do with trolls.

But I did receive 4 other copies of the lens with the clicking sound, so no, even if you discount the bubble lens, my tally is not 0. :)

Interview With Canon Executives

9VIII said:
Along those lines, I'm really looking forward to the implementation of single shot HDR. If you could use digital curtains and pack 1/125, 1/500, and 1/2000 exposures into a single 1/60 shot, then you'd have a hand holdable (for most lenses) single click method of producing HDR images.
It doesn't sound that complicated to implement, does anyone know of a camera that does it already?

I'd go so far as to make use of the dual pixel architecture, just read the diodes with different amplifications, esp as. Canon doesn't have an de facto ISO-free sensor.

16-35 or 17-40?

BL said:
If you buy now and canon releases something else down the line, you're still ahead.

I bought my 16-35 II for $1250 back in 2008. I sold it last year for $1218 on ebay. It's like I had a free 6 year rental and have thousands of images to show for it.

If your gear is clean and looks pristine, L lenses hold their value exceptionally well. Take the pictures you want now and sell it for little to no loss, using those funds to buy the next new thing that comes along.

Thats very true. I usually wait until lenses hit a low point on price when I buy. I have done very well selling them later. Canon L lenses tend to hold their value very very well.

Full Frame Vs Crop Sensor

Northstar said:
privatebydesign said:
It is just magnification and aperture, once you accept that, however convoluted the route to getting there, then it is easier on the mind.

Start to think magnification and aperture and all the inconsistencies and complications fall away.

PBD....you're right, i had always thought of the three.... focal length, distance to subject, aperture....but when i read what you wrote, "start to think magnification and aperture" only....you're right, it's easier to think of it that way.

thanks,
north

Glad it helped, t least one person. ;)

Why Image Quality isn't Everything

And don't forget Bigfoot, countless UFOs, and the Loch Ness monster. Poor photos can be iconic.

I got a snap of the Yeti on a one pixel camera! I love that single white pixel. It gets across the true essence of the Yeti and it was also accepted as solid proof by a leading cryptozoologist.
That sounds like my gigapixel panorama of the blue sky - I've been fielding calls from NASA ;)

Also, I don't know if you guys saw this set of photos (also from India) - I think the 2nd photo was selected as a photo of the year for Reuters or someone:

http://www.dailymail.co.uk/news/article-2016812/Leopard-attack-India-Big-cat-knifed-beaten-village-rampage.html

And yes, I know some of you hate the Daily Mail, but photos are photos and this is the best source for these particular ones

I also found this second (possibly NSFW) set that some might find rather disturbing:

wow, crazy...thanks for posting mack!

On the spot flexible recording settings

One thing I noticed when moving over to the 5D is that when you switch between video and stills in Manual mode it keeps the same exposure settings. So often enough, when I'm taking stills and want video, I don't have to do much adjusting. I was coming from a 60D so this was new.

If you want good quality and you want to get close in-camera, there's no blanket setting that will work. It's like trying to find blanket settings for stills in an emergency. How do you know if your "emergency" will be arise in mid-day sun outside or at a dimly lit event. Any way you slice it, you'll have to adjust on the fly. I would maybe suggest auto-exposure for a real emergency setting... but I know that's hard to admit.
