Lenses / Re: Seeking lens in the 85-100mm range
« on: April 30, 2012, 09:44:35 PM »
I'd vote for the 85mm f/1.8 plus Lightroom.  That Purple fringing can now be removed in most cases, its a thing of the past!
 
Here is a before and after 100% crop of some nasty pupple fringing from my 85mm f/1.8.  The new defringe feature in LR4.1 RC2 seems to work well.

EOS Bodies / Re: 5D Mk3 eyepiece extender???
« on: April 30, 2012, 09:36:12 PM »
The 5D MK III takes the same size eyepiece as the 7D and 1D MK III / MK IV, so you should be able to use the extenders designed for the 7D, but I have not heard if they fit.  I used one for my MK II, but the MK III is different.

EOS Bodies / Re: What if the 5D3 is the stills FF camera and...
« on: April 30, 2012, 09:26:32 PM »
...then 5D3 is the low-mp-high-iso-stills, there's yet to be a high-mp-low-iso-high-dr body between them, the 5D2 is the entry-level-for-now FF...

That's funny that 22MP is considered "low", now...

Yes, 3-1/2 years ago, there was lots of whinning about how it was too high MP and out resolved all the Canon lenses. 
 
No matter what you do, there are some who want it different.  Thats why we should be happy that Canon and nikon are diverging.  If all the cameras were the same, there would be no real choice.

Should I return it to canon or the the dealer (B&H) since I received this lens with the 5D Mark III less than a month ago ?

I'd start by calling B&H to see if they'll just swap out the lens for you.  Else, you'll need to contact Canon Service.

Looks like decentering to me, swap it out if possible, or send to Canon, but do it!

The 5D MK III finally added this, so you can have three file names, the default plus choice of two optional names.  5D and 5D MK II cannot be renamed.

Sounds to me like the emperor who had no clothes! If such a kind of glass really existed, would it be able to refract light? Anti-fogging, self-cleaning, etc., seems like it is just a mist with no refractive properties. Really, I don't know why I'm responding to this post... just happened to pop up in front of me at the wrong time. :)

Like the second poster mentioned, it may be impossible to make a lens out of it. If it really exists, then perhaps it would be a great window glass, to shoot photos through. But it might not refract sufficiently to actually make a lens out of it.

Thats phase 4, there will be 3 phases of million Dollar government grants required before they get to that point. 
 
I'm all in favor of supporting research, but its a shame that Schools like Harvard make fantastic claims in order to get research money.  They have people actually expecting a product to happen, but that is a pretty unusual event.

Not a lot of people use light meters anymore since we have them built into our cameras. I guess the answer is up to Sekonic.

 There are far more Norman, Profoto, and Photogenic users than those with the 600EX-RT. 

But for how long?  Maybe two weeks?

Its likely time to apply for a new government research grant.  Thats when announcements like this are made.  Typically, they get a three or five year grant, so every 3-5 years we see another breakthru.  Research dollars is what its all about, its not about a usable process.
 
In short, don't expect a product soon.
 
Some Harvard research projects have been making fantastic claims and have been sucking in reasearch money for many years, black silicone is a example. It was announced by Harvard back in 1999,  the photos of the surface look very similar, maybe they just recycle them?

They are still pulling in big dollar government research grants.

Lenses / Re: Canon 70-200 2.8 MkI vs MkII
« on: April 30, 2012, 01:30:21 PM »
The recent rebate has me thinking I should take this opportunity to sell my 6 year old MkI 70-200 2.8 and get the new MkII. Recent online sales show a range of $1450-$1600 for a used MkI, that would put me at between $750-$900 out of pocket for the MkII.
Having recently picked up a 5DIII, I have been considering adding the 135 f2 (keeping the 70-200 MkI) but in many of the hands on reviews of the MkII have indicated that those with the 135 f2 use it much less often since getting the 70-200 MkII.
Does the MkII offer such better performance and quality over the MkI to warrant the $1000 investment?

I've owned several of them, the original non-IS (2), the IS MK I (3) and the IS MK II (2).  In terms of IQ, the IS MK I version is a distant third.  Don't hesitate to get the MK II, but if its not good, be prepared to return it.  There are reports of bad ones getting out.

Lenses / Re: L lens vs Full Frame
« on: April 29, 2012, 11:38:14 PM »
The "L" lenses are overkill for a 50D, but a FF body with just a 50mm f/1.4 is going to be disappointing.  Save up until you can buy a camera with lenses.

Lenses / Re: waiting for a new 100-400mm lens
« on: April 29, 2012, 05:25:14 PM »
Now, I am traveling in Nigeria. The wet day is easy to destroy your luxurious lens.  If nothing happens, it would ok. But nobody can guarantee no accident happen. For example, when you go out from an indoor cold environment, into a warm wet outdoor area, you would find your lens covers  foggy. It would probably be wrecked without water-sealed.

In that case, there is no interchangable lens camera that will work.  None of them are vapor tight, so water vapor gets in them all.  Yet, photographers by the thousands seem to have no issue.

If you use Lightroom, they are done at the same time, when you export to a jpeg or 0ther permanent file type. 
 
Before exporting, you are merely reviewing the finished image and can iterate sharpening and NR until you get the best compromise.  Thats what I do, tweak both until I like the final on screen result and then print or export where even more sharpening might be done.  Same if you use the brush to just do local sharpening or NR.
 
If you use a separate NR software, many of them have sharpening tools built-in so once again, you are doing both together.

Lenses / Re: Am I equipped to rip?
« on: April 29, 2012, 02:24:52 PM »
The 50mm 1.2 is definitely not a all-around lens, its pretty special, and a bit soft, but for the special situations where you need f/1.2, its excellent.  Personally, for a FF body, I'd recommend the 85mmL and / or the 135mmL

EOS Bodies / Re: Leave the 5D Mk III, take the 5D Mk II...?
« on: April 29, 2012, 02:20:22 PM »
I have the MK II and the MK III.  Those who purchase the MK III and expect sharper images will be disappointed, its still 22mp, and is not going to be sharper.  However, it is every bit as sharp as the 5D MK II.
 
What you get with a MK III:
 
A better sensor, particularly if you want to pull up shadows or take extreme low light images.
 
You get a far superior autofocus system
 
You get dual card slots
 
You get some improvement in weather sealing.
 
A few Video features thrown in, but nothing earthshaking.
 
Its up to you to decide how much those things are worth to you, for some they will not be worth more, for others, they are worth every penny.
