Lenses / Re: 135mm + 1.4 extender _VS_ 70-200mm f/2.8 IS mkI
« on: September 04, 2012, 03:59:22 PM »
So my original question was specific to the MARK I version of the 70-200mm f/2.8 L IS.

Is the 70-200mm f/2.8 L IS MKI really that bad? Seems like everyone was loving it until the Mark II came out.
I''ve had several of the 70-200mm mk I IS versions.  Certainly, they are good lenses.  Their weakest spot is at or near 200mm, and since you would likely be using a TC with it at or near 200mm, it is disappointing. 
The non IS and the MK II are much better at 200mm and take a TC reasonably well.

Why is it posted as a png.  Thats not a useful format for editing.  provide a link in Raw.

This tech will in military and security use before it will ever hit the consumer market. :P
Yes, DARPA gives out quite a few grants for research to both Universities and to companies.  In fact, thats how we got the internet.

M5 135mmL is my most used lens, its wonderful.  But, it does not like extenders a 1.4X is OK, but the 70-200mm f/2.8 MK II is much better, and it likes extenders.

Actually, its time for Universities to apply for government research grants, and the big ones like Harvard and Mit have large PR departments that churn out praises of their projects.
Nothinng wrong with that, thats how you are successful in getting research dollars.  Just don't confuse it with being something practical or usable.  Its research only, the same as the supposedly 1 trillion frame per second video that is written to make you believe there is a camera that can do that.  Black silicon has been after $$$ for many years now.

I have a lens aligh, but it now stays packed away in its box.  I was a early adopter of Reikan FoCal Pro, its automated for my 5D MK II (semi automated for 5D MK III and 1D X).
Its by far the easiest and most accurate, since it does not require you to make a guess at the sharpest image.
It does require that you print out a target and mount it to a flat surface.  Once you have it setup, the only thing is to be careful not to vibrate the camera while its shooting, and have enough light so the AF system can be at its most accurate and have the least variation.

Wow, that guys jacket and pants are covered with Moire. 
It looks like the anti-alising filter is missing.
I'd send it back for repair both lens and body.

EOS Bodies - For Video / Re: Canon 5D Mark II or a Real Video Camera?
« on: September 03, 2012, 10:25:20 PM »
God, real video cameras are SO MUCH expensive compared to a DSLR :<
The problem with a HDDSLR is that the body is about 10% of the total cost for professional video.  with a Camcorder, its closer to 60%

Both the camera and the lens need to go in for a check and repair.  Just because there is no apparent damage to the lens doesn't mean that the elements are not decentered, in fact, its very likely.

Canon General / Re: Imaging at a Trillion Frames per Second
« on: September 03, 2012, 12:41:37 PM »
I think its very interesting, but it has been around for a year or two.
They are likely talking it up again because they need another government grant. University research projects compete for the government research money, and MIT has a really good PR department.
Its not actually photography at a trillion times a second, thats just part of the PR hype.
You see the same hype with Black Silicone, every time they need more research money, its suddenly in the news.

I do not see any pink goop in the disassembly images, but there is a wire in that area with pink or salmon colored insulation.
Send the camera in for service, its possible the wire has the insulation pinched and pulled off.

Get it sevvices ASAP.  It might not be repairable though.

Yes, the batteries in a 1 Series DSLR are top notch and just plain last longer.  They seem to use ultra premium cells. (Sony does specify different quality levels in their li-0n cells).
