Lenses / Re: How often do you use 35L @1.4
« on: September 24, 2012, 04:15:35 PM »
I use the lens for low light photography, and its usually at the wider apertures.  Its currently my third most used lens (my 135mm L is first by a large margin.)

Lenses / Re: Old manual focus 50mm: Sharpness
« on: September 24, 2012, 01:22:24 PM »
I have a reversing ring and adapters, and have tried several primes.  As noted, you need to use a prime where you can easily stop down the aperture by taping or otherside licking the aperture lever.  Its very difficult to do this with FD lenses, but easy with Nikon F lenses.
You usually need to get quite close to the subject, which also makes it difficult.
The suggestion of the old Nikon 55mm Micro is a good one.  I have one, but do not recall trying it on my Canon gear. You can pick one up for a reasonable price.

Lenses / Re: How to Test a Lens
« on: September 24, 2012, 01:13:09 PM »
Reikan FoCal will help set AFMA, I love it.  Testing a lens / camera combination, which is what all the lens testers do, is a tricky proposition.  The same lens mounted on seemingly identical cameras will give different results, and seemingly identical lenses when mounted on the same camera will give different results.  All of them are likely meeting spec, but there are variations.
I've seen a couple of testers note that the 24-70mm f/2.8 is not as sharp at the edges as its predecissor. but there is enough variation in lenses to require several more test results before we can see a definite trend.
If the lens does not meet your expectations, return it for a second one.

EOS Bodies - For Video / Re: Video Autofocus on Canon 6D?
« on: September 24, 2012, 01:04:50 PM »
The T4i has some kind of continuous video AF, but its half decent. don't even come close to m4/3, NEX, Nikon 1, etc when it comes to video AF.

but the T4i is more for soccer mom, the 6D is not..... but i don't mind shooting my toddler sport activities with a FF A99 that do continuous video AF  ;)
Can you post some of your videos with that A99?  Not too many people have them yet.

Lenses / Re: Vintage Lenses: Any Advise?
« on: September 24, 2012, 12:23:08 PM »
I've found few old lenses that can match even a 50mm f/1.8 for sharpness and color.  The resolution was not needed for film and except for the higher end lenses that are difficult to find, its not there.   
I have several adapters for Nikon, M42, OM, and even Hasseblad.  I have a ton of older lenses of many makes.  They are fun to play with, but most of them (not all) are not up to digital standards.

Landscape / Re: Best lens for landscapes for a trip to the mountains?
« on: September 24, 2012, 12:00:52 PM »
I'd go for the 10-22 plus a 24-105.  For just one lens, a 17-55mm EF-s, but it will not be ultra wide.
I like the 15-85mm EF-s for all around use.
One issue is that the 60D does not have AFMA, and if a rental lens does not AF accurately with the body due to tolerance buildup, you will be stuck.  Why not rent a 5D MK II and 16-35mmL for the trip.

EOS Bodies / Re: Adorama is selling 5d3 for $2745 on eBay now
« on: September 24, 2012, 11:18:07 AM »
I see it arrived in Spokane at 2 AM this morning and is on the delivery truck.  I get deliveries in the late afternoon.. 
Update:  came at 3:00 PM, fresh stock as expected, the battery mfg date is June 2012, and its usually a couple of months older than the camera.  I just finished recharging the battery, formatting my CF card, and took two test shots with my 16-35mm L.  They look pretty good right out of the box, but I've been getting my FoCal updated and targets ready to do a AFMA.

Lenses / Re: Which to get next: 35 f/1.4L or 16-35 f/2.8L...?
« on: September 24, 2012, 11:06:43 AM »
I prefer my 35mmL over my 16-35mm L, but I have not yet used the 16-35 a lot.

EOS Bodies - For Stills / Re: Blown-out Highligts in Stage Lighting
« on: September 24, 2012, 11:04:22 AM »
By now, You know its a common problem.  As you boost ISO's, DR falls.  I've never knowingly shot where led lighting was used. but I still find it near impossible to get everyone properly exposed.  This is where the D800 with its additional DR can make a difference, as long as the ISO stays low.  Its about the only practical advantage to the D800 over my 5D Mark II.  At high ISO's, the 5D Mark III has more DR than the D800.

I thought this lens finally doesn't require correction anymore.

/joke :)
I think its me with my crooked vision.

Lenses / Re: Photozone's review of the EF 24-70 f/2.8L II is up
« on: September 23, 2012, 10:26:16 PM »
My point, I suppose, is that if there is so much sample variation between lenses, it kind of makes lens reviews completely pointless.  They are reviewing that particular copy ( or batch ) or a lens, rather than the product as a whole.  Maybe, we expect everything we buy to be perfect, or maybe those of us who prowl these forums are just perfectionists ( count me in  :) )

I struggle to believe there is that much sample variation.  My hunch tells me that maybe one of the reviewers may be off the mark with their testing.   I think I will reserve judgement until the next set of reviews come through.

And not only that, they mount it to a camera, so you are seeing a combination of camera and lens.  If the camera mount tolerance and the lens mount tolerance are additive, the result will be visible.
A lens testers life is tough, but Klauss is one of the best, so I'm confident that the results are good for the lens he tested.  Some of Roger's tests on his Lens rentals site clearly show the large amount of sample variation that he often finds.

As you can see, even Zeiss has huge variations.  Some lens models tend to have more than others.  I'd expect IS lenses to fall into that category.
Also note that Cameras do show a variation, so the same lenses on different bodies give different results, eving using live view focus. 
There are tolerance buildups everywhere.

Software & Accessories / Re: Does LR4 do away with HDR for you?
« on: September 23, 2012, 09:40:47 PM »
LR4 doesn't really overcome all my lighting issues.  After trying out a D800, I see what low ISO DR can do.  Unfortunately, I shoot at high ISO's and the D800 is not so good at High ISO's.  The 5D Mark III has more DR at high ISO's.  Its in the DXO data, they just forgot to mention it or factor it into their high ISO rating.

It does not happen quickly.  However, its listed in the lens correction lest of DPP. 
I'd expect Adobe to update in 2-4 months.  They usually roll it in with other updates.  Beta versions are usually available a few weeks earlier.

EOS Bodies - For Stills / Re: Who upgraded from 5d mk2 to mk3 ?
« on: September 23, 2012, 08:40:50 PM »
I did, sent back the MK III and bought another MK II.  Then, I happened to snag a MK III for 2750 last week, so I'll keep that one.  $3500 was too much for the improvements to my type of shooting.  $2750 seems right to me.
I just sold my 2nd copy of the MK II for a $200 profit, so I'm waiting for the MK III to arrive tomorrow.  Having already had one, I know it well already, I took 1100 images before returning the first one.  The thing that annoyed me most was the small difficult to see AF points in low light.  There are workarounds, but they are klutzy.  Other than that, everything is a big plus.

EOS Bodies / Re: 450D to 6D
« on: September 23, 2012, 07:35:40 PM »
Why downgrade?

Now, how this is a downgrade? explain!!

Tongue was in cheek, but how about flash sync speed for one.
Hardly a issue for a Rebel User who does not even own a flash.

In that case, I would suggest getting a flash, before upgrading the camera.
Several have suggested that, but the flash sync is still a issue for a very few people.
