EOS Bodies / Re: The 7D for half price

Sure, the same main board with dual digic processors, the same shutter, the same controls.  Someone is playing games here.

Agree the first looks best, but still off a bit maybe...

Thanks but when you say off a bit maybe, do you believe it is front or back focusing ?

Its close to perfect, but compare it with a image that uses contrase detect. 
 
The autofocus system works best in very bright light, and tests should be made wiith a lot of light.
 
Also, your camera needs to be aligned with the lens align tool so that the red in the center hole is not visible (The little hole is centered).  Only then is the alignment good enough to be able to get a accurate and repeatable AFMA value.  I can't see well enough to determine if its centered.

Lenses / Re: Is there a best time to buy new lenses...?
« on: June 30, 2012, 01:31:31 PM »
Prices have been climbing every year, there are usually two price increases each year applied to selected lenses.  The longer you wait, the higher the price.  There are usually sales around Christmas, and with the poor economy, Canon has extended their lens rebate thru the end of July.
 
Last year, Canon had some very good deals due to their poor 4th quarter sales performance and high inventory. They wanted to improve the sales figures for FY 2011.  When that happens, you can catch a good deal.

Could safety be a possible factor in chosing?  Do you really want to fly on a plane with someone who has 6 of the cheapie no QA chinese batteries?

I ordered a Nikon D800 from a local Dealer this morning.  I have a ton of Canon Cameras and Gear, so I'll be replacing some lenses with Nikkor, but keeping my favorite ones to use with my 7D.  I had sold my 5D MK II to finance something new, and tried a 5D MK III.  Its a great camera, but I din't use most of the new features and returned it.  I'm going to try landscape photography with the new Nikkor 14-24mm lens I ordered with it.  My 7D will still be for product photoraphy and focal length limited use, and, of course, I could not part with my 35mmL, 100mmL, 135mmL or 100-400mmL.  My other lenses, flash, TC's, etc will go on the block.

Well, the D800 idea went bust.
 
It was a nice camera, and to start I bought some decent glass, 24-70mm f/2.8G, 80-200mm f/2.8D, 50mm f/1.8D, 200-400mm f/4 AIS.
 
The camera was excellent, and the DR at low ISO was amazing.  However, when I went to print a large image from the 24-70mm, I found a lot of CA near the edges, so much that it could not all be removed in post.  It was ugly.  Naturally, I assumed a defective lens, but checked the reviews and found others commenting about the very high CA.  I also found the AF had more accuracy variation than my Canon lenses, and it was neigh impossible to get the sharpest possible images unless I was in bright light at extreme shutter speeds, or on a tripod.  Since I do low light photography, a super high shutter speed is not possible.
 
So, I sold the lenses, and the body went to a new owner yesterday.  I think that someone who uses it in a studio or is very deliberate and has good light will love the camera, but for low light usage, its no better than my 1D MK IV and maybe no better than my 5D MK II.  I also found that time to post process the huge images was excessive.  Sure, I could downsize them to 21mp or 16 mp, but then I end up with a 5D MK III equivalent and still am unhappy with lens performance.
 
I ordered a refurb 5D MK II thru the Canon CLP program yesterday for $1400 and I'll wait and see what the trusted reviews say about the 1D X before I buy another new body.  I used my 5D MK II for 4 years before selling it to buy a new one, and its a great camera, particularly at the $1400 price.

EOS Bodies - For Stills / Re: Constant AI Servo on 5d3?
« on: June 30, 2012, 12:31:51 PM »
Thats my standard method, I use one shot when the camera is mounted on the tripod, or some other factor makes it better than using AI Servo.
 
Note: The camera is set to AI Servo in the green box mode.

EOS Bodies - For Stills / Re: How much does a dual-card slot matter?
« on: June 30, 2012, 12:26:52 PM »
Grasping to straws if there is any reason for me to get a 5d3 instead of a 5d2 I'd like to get you opinions about the importance of the dual-card slot. Only the 5d3 has it, Nikon puts it even in consumer models like the d7000 which was very appreciated in reviews. The question is: What's it good for?

 
  • Speed: on the 5d3, that can't be the reason because the sd slot is crippled and much slower than udma7 cf. Does it make a difference if writing hires jpeg to sd and raw to cf in comparison to writing both to cf like on the 5d2?
  • Reliability: brides are said to be somewhat grumpy when your no-name budget cf card breaks without jpeg backup on a second card, if you are a high profile shooter this could even ruin your business. The question is: how large is the likehood of cf/sd cards breaking without being recoverable, and are there differences between brands?

The value will vary from zero to very high, depending on the user and the potential for loss. High end photographers who spent 100K hiring models, trucks full of lighting, assistants, etc stand to lose a lot of money.  They are very careful about backups, and use multiple backups in different locations.
 
A wedding photographer who does not do something simple like making a backup might be subject to a lawsuit, because its a forseeable event to have a card failure.  Even if you put not liable for equipment failure in your contract, you can be sued for negligence, because it might be construed that way.
 
So, if you don't have dual slots, have a second photographer so that not everything is lost.  Legal liabilities different from country to country, and even location to location. 
 
Another possible solution is to spread your images over multiple cards by changing cards frequently.  This means if a card fails or something happens to it, all is not lost.  It also increases the odds by a large amount that something will happen to one of your cards.

EOS Bodies - For Stills / Re: Get the 60d or wait for the 70d?
« on: June 29, 2012, 11:33:36 PM »
Although I don't usually recommend waiting, the 70D may be coming on July 24, and i'd wait and see.  The T4i has some new features that will likely appear on the 70D. 
 
We might see hybrid autofocus which gives some level of autofocus during video, a touch screen, digic V processor, and we can always hope for AFMA.  Those features alone would be worth waiting for.

Welcome to CR.  The Canon 60D is a very nice camera, I expect a replacement model with more features to be announced soon, perhaps a touch screen, autofocus while taking video, optimized for the new STM lenses, etc.  It might be worth waiting.
My main arguement against the 60D is that you can not use AFMA to fine tune the autofocus to match any AF error in your lenses.  It doesn't matter too much with the kit lenses and their smaller apertures / depth of field, but when a user decides to go for a wide aperture f/1.8 or f/1.4 lens, for example, they will always benefit from fine tuning, the alternative is to send the lens and camera body to be adjusted, and then the next new lens will be off.

I found that it was difficult to intrepret the lens align images, I setup the camera and took a reference image using contrast detect in live view, and then tried to match what I saw by adjusting the AFMA.
When I switched to using FoCal, life was much easier, since the software does a sharpness analysis of the image, and I have never found it to be wrong.  Wide angle lenses are just difficult due to their depth of field.  I think the top image looks best.

EOS Bodies / Re: Why so many different camera bodies?
« on: June 29, 2012, 05:05:21 PM »
It cost too much to bring old junk cameras back to earth, and they are not allowed to litter the spaceways.

Pre orders are starting to be delivered to Olympic Photographers and big news agencies, you are not going to find one sitting in a store for 6 months or more.

Lenses / Re: Best Lens for Tabletop Dinnerware Shoot
« on: June 29, 2012, 04:50:50 PM »
For tableware closeups, the TSE-90 is excellent.  Lighting might be a big concern, reflections are killers.
Even if I use a 3 light softbox set-up?
You might want a sparkler to put highlights where you want them, otherwise, no reflections.  I even have problems with reflections due to room lights.
