Speedlites, Printers, Accessories / Re: Lexar CF cards FAIL - Sandisk?
« on: March 10, 2013, 02:02:56 PM »
No,  my Lexar cards are fine.  Sandisk is reported  on this forum to have some issues.
 
How many cards failed?  You make it sound as though you have a lot of them and they all failed.
 
Individual cards fail, and, of course, counterfits fail frequently.  Even batches of a certain lot can have a die flaw.
 
Which cards failed,?  Is there a serial number laser engraved on the back edge of the card.  I'd ask for it, but mine is a very long code and I'd likely make a error copying it. (Its hard to see, because its engraved on black)

Pricewatch Deals / Re: 70-200mm f/2.8L IS II Refurbished for $1699
« on: March 10, 2013, 01:51:10 PM »
Although it ends up only saving $200 net, I ordered one just now. 
 
Thanks for the tip.
 
I'm going to sell off some of my lens collection to pay for it.

I'd be a little careful buying filters on ebay.  They are so easy to counterfit that there are tons of them being sold.
 
You might be better off buying Quantaray, they are claimed to be currently produced by THK, same as Hoya (USA) and Kenko (Europe).
 
THK is a acronym for Tokina, Hoya, Kenko and is the parent company.

I've read that one forum administrator had his fail in the middle of a wedding shoot.  I think the flashes are fine for casual users, but putting your expensive wedding shoot at risk to safe a few bucks might bite you.  I guess you could always buy spares, and toss them as they die, but you might still lose a critical shot.
 
They did have a modification to the 560  in 2011 after the early models were dropping like flies, haven't heard a lot of complaints lately.
 
Canon flashes die as well, so you have to asses the risk.

Lenses / Re: Need help with choosing a telephoto for $800 and under

I'd also vote for the 70-200mm f/4 either non IS or a used IS version.

4206
I'd be concerned that the issue with the focus ring is the common damage to the collars that guide the lens barrell as it moves.  If one or more cracks, focus gets rough.
You can pay to have it cleaned, but you may then pay again to have it fixed.
 
Canon no longer sells parts to small camera repair shops, so even for a 2 cent part, you may have to send it to Canon or one of the very few authorized repair centers.
 
This article discusses the issue with the collars:

EOS Bodies / Re: Really...How "Bad" is the T3i For Video?
« on: March 09, 2013, 10:28:53 PM »
Sound is 50% of the video, and the live sound is pretty noisy, she needs a proper mic, or to overdub the sound.  She should also hire someone to run the camera.  Its just apparently mounted to a tripod and looks itUsing multiple cameras would be a help.
The T3i is fine, the weakest part is the sound and the look of the camera just sitting on a tripod.  I liked the music.

4208
If they were the same part, Canon would (or should) have the same part number on them. 
Did you contact Pro Camera Repair in San Diego?
 
Give them the dimensions and they might have one close that could be trimmed a little.

If it were me, I'd stick with 5D3.  1DX and 5D3 got the same AF (almost).  As for low light performance, 1DX is just a little bit better.  I suggest getting 1DX only if more than 6fps performance is crucial to you.  Your macbook is also important since it is so good to edit raw files using mac.  If I were you, I'd like a good TS-E lens instead of the 35 though.  :)

Sorry if this sounds stupid but what would be the application for a ts-e?
Its a good question, a TS  is a specialized lens why would someone recommend it for you instead of a 35mm lens without knowing what use you would have for it??

You can use the Kenko TC by turning off AFMA in the camera body, or use the canon TC by inserting a extension ring.
 
Just for the heck of it, and since it is a sunny afternoon, I tried some different combinations with my 5D MK III and my 100mm L.
 
First, a short extension ring.  That worked and so did autofocus, its a reasonable handheld near 1:1 solution.
 
Then, I put the camera on my light table mounted to a sturdy bolted down head.
 
I used liveview to try the tube, tube plus canon 1.4X, tube plus Canon 2X, and tube plus both TC's.  In all cases, I was able to use live autofocus, but the image without TC's and just the tube was the clearest.
 
I also had a old non reporting 2X TC (Quantaray) which came with a used film body.  It did not need a tube, live AF worked fine.
 
Then, I took the tube and Canon TC's outside into the bright sunlit outdoors to try phase detect AF.  It was unacceptable in all cases, and could only rarely fix on the target.  I tried both AI Servo and one shot.
 
Just the short tube worked fine.
 
So, with a tube and TC, the camera will not autofocus in any soet of reliable manner.  This is my second 5D MK III, as I recall, the first one worked the same way.
 
If you are doing live view AF, use a self timer, and it will be acceptable with a 1.4X, but just tubes might be better if you can get close enough. Manual focus works as well, of course.
 
Good Luck.

Lenses / Re: Any news about the 200-400
« on: March 09, 2013, 06:28:19 PM »
It will be posted on the main page when there is a rumor.  A announcement is hoped for this year, lens announcements are kept very secret by canon and often do not leak.  Canon bans anyone leaking the information from receiving it in the future, and they are very good at keeping it secret.

Thank you both very much for your replies. Your answers are extremely helpful and it sounds like the newer SDHC USH-I  cards are the way to go.

You also both mentioned the sped of the cards. I mostly plan to shoot skills, but maybe some limited video. Also, while most of my shots will probably be single shot, some pix may be shot using continuous. Any additional advice on the speed of the cards would be appreciated. Should I just get the 95MB/s cards to be safe?

And, finally advice on the size of cards would be helpful. Is there any image quality differences among the different sizes?

First, you may have been given some incorrect information.
A SDXC or SDXC UHS-1 card is not compatible and will not work in a T1i.  There may be a firmware update, but I haven't located one.
It will work at reduced speed in your S100.
 
Also beware of card write speed ratings. 
The claimed high write speeds are only for a new or erased cards.  Formatting a card in camera does not erase it unless you do a low level format.
A low level format takes a long time, and might eatup your battery if done in camera.
The only cards compatible with all three cameras are SDHC cards.
 
Be sure to update firmware in all three bodies.
The size of the card does not make a difference in image quality.  SDHC cards are limited to 32GB while SDXC cards are commonly found up to 128GB

One of the improvements in LR4 is that you can selectively apply NR by using the brush.  This lets you sharpen only the features that benefit such as hair, eyes, etc.
Photoshop has layers that let you do this and has had for years.
 
The dedicated sharpening software works well, being able to apply it selectively is something to look for when you try them.

4214
Canon says to not charge the E4N with the old charger, I'd take their advice. 
I'd go ahead and get a LP-E4.  It will last for several years and you don't have to worry about safety or failures when you need the battery to work.

Lenses / Re: Photo jargon question: f/stops
« on: March 08, 2013, 10:14:34 PM »

I don't exactly understand the "Why the smallest, or the sharpest", but the fastest lens I've heard of is probably f/0.95, of which there are a few. Probably the best known current production lens is the Leica 50mm, but Canon had a 0.95 50mm back in the day.

Lenses are named by largest aperture simply because its the largest aperture that determines the value of the lens (assuming its a normal quality lens).   The smallest aperture does not really cost anything, but it limited since image quality gets pretty poor at extreme small apertures.  For larger the film or sensor sizes,  smaller apertures can be used, so its relative.
 
The Zeiss 50mm f0.7 is one of the fastest lenses.
 
"Carl Zeiss Planar 50mm f/0.7 is one of the largest aperturelenses in the history of photography. The lens was designed and made specifically for the NASAApollo lunar program to capture the dark side of the moon in 1966.
Stanley Kubrick used these lenses when shooting his film "Barry Lyndon", which allowed him to shoot the scene only by candlelight.[
In total there were only 10 lenses made. One was kept by Carl Zeiss, six were sold to NASA, and three were sold to Stanley Kubrick."
