Lenses / Re: Canon 28 1.8

So you are saying an EF 30mm lens will be the same as an EF-S 30mm lens?

The focal length will remain the same.

The image circle created at the image plane will be definitely small and as a result a smaller sized "field of view" will be captured at the image plane.

And as Canon builds them, the EF-S one cannot be mounted on an FF body (unlike some third party manufactureres).

Are you saying these are wrong? On top of that I need to clarify whether the perspective of a lens is a function of focal length or field of view?

Please don't read more into my post than I posted.  It was a simple question and not a trick question at that.  Which part of my question made you infer that I was saying you were incorrect?  I believe all the guy wants is an EF-S lens with a FOV-equivalent of 50mm but with a smaller sized field of view capture at the image plane.  That seems like a simple request.  Why read so much more into it?  Will the two images taken result in the exact same view, one with an EF 30mm vs. EF-S 30mm lens?  I don't really know.

I'm using my mk3 at a paid wedding job tomorrow and i'm a bit nervous about the AF points.

Use the single shot blink red option, and you don't need to worry.  You don't need to worry anyways, I've shot a ton in very low light and using center point AF I've never had a problem.  Good luck!

Lenses / Re: Upgrade 300 F4 IS with 300 f2.8 IS
« on: July 13, 2012, 09:34:48 PM »
Well, I just won a used 300 f2.8 (and a used 1.4x II) on eBay. Hopefully the lens is as mint as the seller and images said/show. If so, the 300 f4 will be listed a few days later.

Appreciate all the replies, looking forward to getting outside with these new toys.

Go outside and set it up on a tripod, then pick an object and open the lens up to 2.8 and fire off a few shots, perhaps using 3-shot AEB.  It has something special the f/4 doesn't have.  Then stop it down to say, f/8 to f/11 and it just keeps getting better.  Congratulations and you won't regret it one bit.  I rate it in the class of the 200 f/2L.

The real question is this: Why has Canon left crop users in the cold by not releasing a "normal" prime in an ef-s mount?  Buying an ef 24, 28, or 35mm lens to substitute a "normal" on a crop body is stupid.  You'll have a close to normal focal length, but you'll have a wide angle perspective.

Fail.

EOS Bodies - For Stills / Re: My Canon EOS-1D X Has Arrived!

Mine is here!!! ;D

Looking at the handbag I have to wonder if you had your priorities right here and your wife was sitting in the back seat or you are a wife and the husband was sitting in the back seat  ;D

Yes, he has his priorities straight.  1D X in the front seat, wife in the back.  It's simple.

EOS Bodies / Re: 5D Mk III vs D800/E, is the 5D3 better at anything?
« on: July 13, 2012, 07:16:51 PM »
I think Bosman is referring to the rate of return.  Storage size goes up drastically (22mp vs 36mp) with highly diminishing returns in IQ.  So why do it?

May I suggest that with more MP more thinking takes place before the shutter is pressed?
That is certainly true with MF digital.

You're inferring then, that with less mp, less thinking is going on.  I beg to differ as I have a 16mp 1D Mark IV and I can tell you I think no less than if I had a 36mp camera.  I put great thought into my photography, regardless of camera.  Yes I also have an EOS-3, which hurts my brain sometimes  ;D

Interesting - ff fans say with big mps we can crop out the picture and also we would have to think harder  before taking the picture. Sounds like there is a gap in the thinking there

Brian, there was no thinking going on by that person's comments.  None.

The final Prime I need to obtain is the magical 200mm F/2. :o

Get in line at B&H.  July 31 estimated availability if you are hardy enough to spend the money  ;)

whichever mid-range zoom i get, would become my walk around lens.  Since i was hoping to take pictures of people mostly, i figure the IS wouldn't be as useful as say the small aperture.  I do have a 600ex, but have had limited success in using it at bars as the ceilings are all kinds of colors.  But this is just lack of experience, and something i plan to practice more with.

I'd save the primes for portraits and low light.

Right.  I guess what I'm trying to say is that opening the aperture isn't always the way to go.  If you open it up too much in the bar, yes it's dark, but most of your photo will be out of focus.  If you shoot at f/2.8 at 70mm, I've seen shots where the nose is very sharp and ears are slightly blurred.  If it's a general walkaround lens I'd still argue for the 24-105L.  If you have the funds and know you only need up to 70mm, then yes of course, wait for the 24-70L II lens.  On my FF the 24-105L is my most used zoom, behind the 70-200L.  Even indoors I never shoot wider than f/4 because I'm a DOF guy, I like a good amount of DOF.  Only time I don't care is portrait shots, which, with the 600EX-RT, is more than sufficient if you get to know how to use it to shoot at f/4.  However, I use a prime anyways for portrait shots and wouldn't even use a zoom. 

I still just think that you'd use the 24-105L more than the 24-70L, which is sort of specialized.  You need to evaluate closely which shots you'll be taking, what DOF you want, what lighting, and where you'll be.  With a 5D Mark III though, you can shoot at higher ISO values than before, so that will allow you to shoot at narrower apertures.  Heck I shot a few at 12,800 this past week and was able to do NR and print them on photo paper and looked completely fine, and I was at f/6.3.

EOS Bodies / Re: Why are you buying the 1D X?
« on: July 13, 2012, 09:44:43 AM »
I checked out Bryan Carnathan's review of the 1D X (or partial review).  I looked at the ISO charts and at ISO 6400 and 12800, the difference between the 1D X and 5D Mark III really isn't that signifcant and nothing that couldn't be quickly equalized with NR (which you'd have to use for the 1D X image anways).  I don't really see a HUGE ISO advantage from these charts at least. 

http://www.the-digital-picture.com/Reviews/Canon-EOS-1D-X-Digital-SLR-Camera-Review.aspx


Not sure I agree about the equalizing with NR - sure, you can NR the 5DIII image, but you can NR the 1D X image, too, and the relative difference will be maintained (or sharpness will go down if you NR the 5DIII image more). 

But I do agree that while the differences there and visible, they aren't huge.  However, IQ isn't intended to be a differentiator, any more than it was between the 5DII and 1DsIII.  For that matter, in terms of ISO noise, the relative difference between the 1D X and 5DIII is similar to the relative difference between the 5DIII and the 5DII - so if that's the main concern, the 5DII is a much less expensive way to get there...


I agree 100%.  The other aspects of the 1DX do make it a better camera, overall, than the 5D3 for sure.  I too want those advantages which is why I'm getting one.  I also agree that applying more NR, even if just a few percent, will overall make the 5D3 image with less quality than the 1DX image, at the end.  This was just a very narrow observation I had made.

Lenses / Re: Which L lens will be the first mark III?
« on: July 12, 2012, 08:45:31 PM »
Sorry, I meant the 35 f/1.4L II lens would be out before any other of the lenses had a Mark III, not 1.2.  It's hard to have a 1.2 Mark II when there isn't even a Mark I of those yet I suppose? 

And yes, I agree.  When I'm using my 24-105L lens, I find myself shooting at 65-70mm at least 80-90% of the time.  Get me a 65mm f/1.4L  8)

Thanks for the advice. 

Looks like i'll need to take another look at the 16-35 and 17-40.

Hey, I would not choose the 8-15 for the landscape shots either.  I do shoot a lot of landscape and my personal recommendation, for the price, would be the 17-40L.  Some buy the 16-35L but why?  My landscape shots are at f/8 and narrower.  However, I do own the 16-35L because I use it for other things, such as very low-light, tight room indoor shots.  With landscape photography, I was shooting with a 24 and 35 prime, but the zoom lens offers me much more convenience and flexibility.  I think if you want to only use it for outdoor landscape, 17-40L is YOUR lens.
