That's called a review these days? Amazing. Why not make a head line out of the other 100 reviews of that lens?

The kit price dropped another $50 this morning at B&H. $2,399

Just the 24-105 kit or the body as well?

Lenses / Re: New Tokina AF 16-28 F/2.8 AT-X Pro SD FX - Focus Pocus
« on: February 10, 2013, 02:54:37 AM »
I finally decided which UWA lens to get for my 5DM3 and took delivery yesterday of the Tokina 16-28.  I made that decision based on the large number of positive reviews I'd read.  I especially wanted it for its sharpness edge to edge, as I'm not getting that with my current widest lens, the 24-105 kit lens.  The Tokina is a nice solid, heavy lens that appears to be well made.  I took it out to my normal lens testing spot this morning, on a tripod, cable release, etc running a large number of shots at multiple apertures, focal lengths etc.

 My problem is two-fold, which are probably related.   In Live-View mode the lens just won't ever come to a focus - occasionally it appears to lock-on, but I can tell looking at the screen that it didn't lock on in-focus.  It was a bright sunny day, so it isn't a lack of light issue.   I don't use Live-View focusing that often, but wanted to compare the focus with the standard viewfinder focus, to see if any AFMA was going to be necessary.   Since I couldn't get Live-View focus to work, I did the next best thing, which was to use the Live-View mode, go to 10X magnification and manually focus.  The Tokina has a unique method of switching the lens from AF to MF - you slide a ring on the lens.    What I found has me stumped.  I was focusing on a rock outcrop probably 50 or more yards away in the center of the shot.  Both the manual and autofocus were in pretty good agreement in the center of the image, although the widest-aperture shots, 2.8 and 4.0, were better in manual focus, suggesting some minor AFMA is going necessary.  The problem is with the sides of the image.  Regardless of focal length, or aperture, the left side of the image would be blurry using manual focus, and the right side would be sharp,  the AF images were just reversed, ie the left would be sharp and the right would be blurry.   It isn't a depth of field issue (at 16mm most everything at f8.0 should be in focus), and the out of focus sides are both near and far objects in both cases.    I had my old trusty t2i along with me so did the same set of tests with it.  Same problem in that it would never focus itself using Live-View.  Again comparing Live View zoomed manual focus vs viewfinder focus, one side is sharp and one fuzzy, with the sides flip-flopping depending on focus method.   It's almost as if there is a out of alignment element that gets moved out of alignment the opposite direction when shifting from MF to AF.     

Has anyone who owns this lens seen this sort of problem?    I'm pretty sure I'm going to send this back and see if I just got a bad copy, unless someone here has a suggestion in the next day or two.
I don't own that lens but was looking at it today, it didn't really impress me. It might be a decent lens if you get a good copy but  in your case I would definitely send it back right away.

EOS Bodies / Re: Possible positive 6D surprise? Should I wait?
« on: November 26, 2012, 09:57:02 PM »
I realize the AF seems to have been deliberatively crippled (and overly-so!), but for shooting portraits and candids and casual soccer of my kids, I really don't need the pro athlete or bird-in-flight AF.
Crippled or better, depending on your needs.  The 6D is supposed to focus in even lower light than the more expensive 5D3.  For some photographers, that may be a significant advantage.  Of course it will not be as good in other ways.  I'll be very eager to see how well the 6D's AF performs generally.

By the way, everyone says "crippled" about less expensive cameras, as if to suggest some bad intent on the part of the manufacturer.  "Crippled" suggests that they start with an excellent AF system and then damage it terribly.  But less expensive cameras are less expensive for a reason — less goes into them.  The lesser AF system is designed for a lesser price, from initial concept to production. 

Manufacturers have to differentiate their products somehow.  We do it as a photographers.  We differentiate our products according to size, hours, materials, etc., and yet we don't say our cheaper products are deliberately crippled.

Whilst I will reserve judgement on the 6D's AF system until we seem some credible reviews, I think that people are using words like 'crippled' because the 11 point system with but a single cross type sensor (however good that might be), is perceived to be inferior to even the 9 point, all cross type system on the 650D.  The D600 uses the AF system from the D7000; I think that people were expecting some version of the 7D's 19 point (all cross type) AF system on the 6D; when you are disappointed, you tend to use emotive language.
Anyway, the 6D's cross sensor has a higher sensitivity than all other models mentioned.

There is Sony XEL for example.

http://en.wikipedia.org/wiki/Sony_XEL-1

OLED is just not mainstream yet thats why u didnt hear much about it :)

Well, it's no surprise no one knew about it. Its a joke...practically microscopic in size, with an oddball resolution, and a truly hideous design. If I was Sony, I wouldn't have even bothered releasing the thing. That's like being one of those idiots who always has to post "First" in every forum they come across...just to be...first. I'd barely qualify that thing as a TV, and while Sony may have been the first to market with some kind of OLED device that might possibly stand in as a TV for some dude somewhere in the world...its kind of a stretch. Give me a nice 52" HD TV with OLED technology that produces a better quality picture than LED technology does, and then you can call "FIRST!" :P
Why would anyone buy an OLED TV? The lifespan is too short, doesn't make any sense. Otherwise you would have seen bigger OLED TVs already.

Both could possibly be available in the 3rd or 4th quarter of 2013.

Hopefully the one saving specification the Canon could have at this point might ironically be the 11 point AF system... wait, I know what your thinking, hear me out...

From what we've seen of both Nikon's and Sony's offerings, they're using AF modules borrowed from their APS-C cameras, meaning they occupy a tiny little fraction of the frame, all clustered into the centre. Aside from subject tracking, which these cameras are not made for, and which the Sony will (based on specs alone) probably only marginally excel at, having all the AF points in the centre is a nightmare for all sorts of photographers who would like this as a secondary body, and for those people as basic as an 11 point AF seems, its better than a "19+109 point" that covers a fraction of the frame.

Here's hoping that Canon manage to bring out the only entry level FF with FF AF.

AF systems are basically the same size for APS_C or APS-H or FF so not sure what you mean buy that....

mmm.... are you sure? I was very much under the impression that AF area was linked to prism size which is linked to sensor size.

Look at the AF area coverage of the D600 here : http://forums.dpreview.com/forums/read.asp?forum=1021&message=42484333

And the Sony A99 here: http://4.static.img-dpreview.com/previews/sony-alpha-slt-a99/images/screens/AF-Range.jpg?v=1581

Both, but particularly the Sony are tiny compared to the frame coverage of any of the 5D's.
No.

Is anyone else worried about the 102,400 Screen Dot resolution of the screen, when most new Canons have over 1 million? Is this a typo?
Nobody is worried about it because it's a typo obviously. Jeez...

Looks like the formatting of CRguy's post is still a work in progress, but... is that 5D2 AF?  Again?  Even the Rebels get better AF these days...
No, it is some new 11 point system.  I don't know why they didn't use a more expansive system, or even rehashed one of the older 1D series 45pt system.  Only one cross-type point is pretty much unacceptable.
I agree. :(

I think you need to get yourself more familiar with PDAF sensors, mate. ;)

5D3 Samples: LINK http://www.glenargov.com/Other/5D3-Test/24800438_Zw5jbH#!i=2029849496&k=73Mshxf

Looks a bit too mushy for a full-frame sensor. Though, I don't think it's a reason to return it. It's still a great camera and I don't think you can get better results from a Canon right now.

Are the bodies where the serial number's 6th digit is greater than 2 all fixed with duct tape ("proprietary weather/light sealing material") too or did Canon redesign the camera internally a bit?
My understanding is that they changed the design a bit... I could be wrong though.
Interesting nobody seems to know how Canon fixed it. :P I don't want to buy a body for SG$4k with duct tape inside. ;)
