Canon General / Re: Filters: Cokin P Series "Equivalent" quandary
« on: November 02, 2011, 04:43:47 PM »
The Cokin P filter holder has three slots.  If you don't mind having only two slots, here's what you do: take a sharp utility knife and cut off the outer slot from the filter holder.  Voila, no more vignetting.  This 5 minute fix has served me well.

Good idea! ... however would like to know how wide can you go with 1 slot cut off (2 left) i.e. is 24mm ok?

I should have mentioned that I fixed my Cokin P filter holder for my Sigma 10-20 in this way.  So I can't tell you exactly how it's going to pan out for a 24-105 on a 5D.  However I can tell you there's quite a bit of gain in FOV.

The T3i is a really nice camera.  Go for it!!  Be sure to get the two kit lenses, 18-55 and 55-250.
You may be able to save some by getting a T2i.

EOS Bodies / Re: what the 1Dx may tell us about the 5Diii
« on: October 30, 2011, 01:24:26 PM »
i hope the new 1dx is telling us alot about the up coming 5dii ... i hope the ff sensor stays the same, no need for a larger mp sensor.  whats the point?

The point is: studio photogs and landscape photogs want more megapixels.

My guess is 5D3 early next year.  36 mpix,  iso characteristics similar to 5D2 on a pixel-by-pixel basis.

EOS Bodies / Re: Nikon D800 at 36mp, Will Canon Respond?
« on: October 05, 2011, 01:25:56 PM »
Ideally Canon will release:

(1) a 36 mpix cam for landscape and studio work.  No blazing fast fps and high iso here.  Maybe the 5D3?

(2) an 18 mpix FF photojournalism/sports cam with beefy build quality, dual card slots, top-of-the-line AF, 7-10 fps, and amazing high iso.   Maybe 1Ds4?

(3) no more APS-H.  1D5 = 1Ds4.

Not a prediction, just thinking about ideal uses.  This way the 5D3 doesn't really compete with the 1Ds line like it has in the past.  It would also align things better with Nikon's D800/D3 line.

Question then is price.  $3k is fine for camera #1, but $8k for #2 would be a problem.  Maybe they can give #2 a 7D like build quality, price it at $3-4k, and call it 3D.

EOS Bodies / Re: Opinion - What EOS Will Look Like by Photokina
« on: September 23, 2011, 10:58:16 PM »
I think the digic5 will make it into one or more of the dslrs this year.  Probably enough of a change to go from 600D to 650D.  I wonder what bells and whistles the digic5 will enable for video.

As for new sensors, I guess we'll just have to wait and see.

EOS Bodies / Re: Nikon unveils V1 and J1 Mirrorless Cameras
« on: September 22, 2011, 10:59:39 AM »
... you land up with a product which is rather like a motorbike with a sidecar - it inherits the disadvantages of a motorbike combined with the disadvantages of a car, and only satisfies a small market segment.
And you price that motorbike-and-sidecar higher than a fully loaded Honda Civic.

The lower end of the market could probably not care less about interchangeable lenses - they are perfectly happy with a compact. 

The higher end of the market insists on image quality - these users already have DSLRs and need a pocketable camera.
I agree with you.  I just don't see the market here.  And here we have a brand-new sensor and brand-new line of lenses.  Chances are, if this thing doesn't sell like hotcakes (probably won't) then prices won't come down in a hurry.  Olympus PEN hasn't exactly taken the market by storm.

I think if you look at it as a point-n-shoot with higher image quality than its 1/1.7" brethren plus the ability to change lenses, well then it's kinda interesting.  The price kills it though.

If you look at it as a mirrorless DSLR system with a miniature sensor and the same price as a proper APSC cam, then forget it.


what an epic fail....  i only hope canon will do it right.

Epic fail... I say probably, likely.

I sure hope canon gets a mirrorless system going with its APSC chips and an EF-S lens mount.  Why manufacture a whole new line, no upgrade path?  I just don't get it.  Why not use components already being manufactured?

Lenses / Re: Canon EF 100-400 f/4-5.6L IS Patent Pending
« on: September 20, 2011, 11:03:56 AM »
I suppose another way to look at this is that a 100-400 mk2 isn't just around the corner.  It's still early in its development phase.

What's your budget?

Have a look at Sigma 120-300/2.8 OS.  Not a light lens, though.

A 5d2 sensor in a Rebel body: plastic + pentamirror.

Sounds like an awesome travel + hiking camera where every gram counts.  I'd definitely buy it.  But I doubt that this is gonna happen any time soon.

EOS Bodies / Re: APS-C Camera with an L Lens as a Kit
« on: September 13, 2011, 03:40:42 PM »
There are a few 60D plus 15-85 kits out there, if you shop around a little.  You may be able to save some dough.

e.g. here in my city

EOS Bodies / Re: APS-C Camera with an L Lens as a Kit
« on: September 13, 2011, 12:40:26 PM »
Then how do you know if you're going to stick to full-frame?  Maybe full-frame won't be good enough for you at some point in the future, and maybe you'll upgrade to medium format someday.  Shouldn't you be buying medium format lenses, to be used with adapters, just in case?

I'm just playing devil's advocate here.  The point is, buying a lens is not like marriage, forever till death do us part.  Lenses can be sold just as easily as they are bought.

15-85 is apsc-only because it can't project a 15 mm ultrawide image on a full-frame sensor.  Restricting the imaging circle has its design advantages, and makes a high-performance 6x zoom possible.

I suggest deciding on a format now and sticking with it.  Either get 5D2 plus 24-105, or 7D plus 15-85.

United States / Re: Why a shutter curtain?
« on: September 08, 2011, 03:59:47 PM »
I think originally it was meant to prevent sensor blooming in bright light.  I'm not sure if this is still an issue today.

Another advantage of a shutterless camera: flash sych speed = max "shutter" (acquisition) speed.  i.e. 1/4000 or 1/8000
