Lenses / Re: I have a weight limit....what would you bring?
« on: May 17, 2013, 05:17:10 AM »
Right now, I am planning to bring my 70-200 f/4 IS, my 24-104, and my 17-40.

Do you really need to fill that 40-70mm gap? 17-40L + 70-200/4L IS could be enough.
OP seems to have one camera so that would cause lens change more often. Still it remains an interesting combination...

Lenses / Re: Poll: Most Wanted New Lenses of 2013.

Can we have ALL please ? (wishful thinking) ;D

Seriously though, that would be extremely bad for our wallets. It's better having each one every year or two (more wishful thinking)  ;D

Lenses / Re: When is the New 100-400 Coming?
« on: May 17, 2013, 05:04:28 AM »
If they produce a 100-400 that's a "twist" and is as light and small as my 70-200 F/4 IS with 4 stop IS and IQ as good as what we've got now, and if the price is less than $2000, I would jump.  But, that is impossible form an engineering and design and financial perspective.
If I were to just guess (I obviously have NO inside information) I would say that it would look like the bigger (and  heavier) brother of 70-300L ... Now the price would be higher too...

Lenses / Re: Can the 70-200 2.8L II IS replace my 100L and 135L?

I find it extremely hard to sell Lenses I no longer use so much, almost like selling my Children.
I understand what you mean.

But, I sold lenses I didn't like or need (and the battery grip of my stolen 40D) and saved a lot of money getting new camera and ... L lenses.

Only 1 was an L lens. The others were old non-L from the end of 80s or the early 90s (and 2 of them were SIGMA lenses)

So it depends.

They are different. I cannot comment on 100L since I do not have it but I have the other two.

135mm: discrete, light, excellent for shooting at f/2.0 - f/2.2
70-200m: Excellent but... heavy and conspicuous.

But, it all depends on the specific use. Also I take with me either but not both depending on what I want to do.

I admit I enjoy the 135 more. But this is subjective...

(Sorry I didn't help)

The Samyang's 14mm distortion is only a problem for architectural photography. You will have no problem for the type of photography you want.
Keep in mind the 500 rule:

500 / <lens focal length> is about the maximum you can shoot in seconds to avoid star trails.

So for Samyang 14mm it is 500/14 = a little more than 30sec (35sec actually so 30sec is a rather safe selection).

Even so you will see some star trails at 100% or more...

The more the megapixels the more star trails you get for the same exposure!

Since 40D is an APS-C camera it has the pixel density of a 10*1.6*1.6 = 25.6 Mpixels.
You may need to decrease the exposure to less than 30sec.

EOS Bodies - For Stills / F/8 Autofocusing impressions
« on: May 16, 2013, 12:56:51 PM »
Now that 5DMkIII has been upgraded to support f/8 autofocusing have you tried using it? Of course this question applies equally to 1D series owners too.

1: Do you find AF practical/fast/accurate ?
2: How is the quality retained? 

Well, I know that the latter is NOT f/8 autofocusing related but now that this feature is available it may invite more and more people to try using it (instead of just watching the excellent the-digital-picture site). Apart from the new generation super telephotos that can probably handle the version III teleconverters well, how smaller/cheaper Canon lens/teleconverter combinations work? (for example EF300MM f/4 with 2X, EF100-400mm with 1.4X, EF400mm f/5.6 with 1.4X)

I am thinking mostly Canon lenses with Canon II or III series teleconverters but feel free to comment on any camera/lens/teleconverter combination you want regarding autofocusing and quality issues.

EF-S 400 4 IS

Why not try the EF 300mm f/4L IS, as it is the equivalent of 480mm on a 1.6x crop body?
Maybe because it would be the equivalent of much more mm (actually 640) on a 1.6x crop body and some need it?

if you have sources to tell you that there are prototypes.

why don“t they tell you at least if it is a push-pull design or not?

or is a push-pull design tested and a "normal" design?

Lenses / Re: Who has pre-ordered or will order 200-400
« on: May 15, 2013, 01:55:46 PM »
See now I have a dilemma...I have been saving my money to purchase the 400mm 2.8 for the past couple of years and I'm about $1500 off from paying straight cash for it. I am planning to have it by the time fall rolls around for some high school football action. Now with this lens finally becoming a reality I wonder should I just go ahead go for this or just go ahead and pull the trigger on the 400 since I've been saving for it for so long...

Decisions, decisions...
Unless you will need less than 400mm I cannot see why you must change plans.

400 2.8 L IS II weighs the same as the 200-400 and is one stop better...

« on: May 15, 2013, 10:53:14 AM »
Am wondering what gear we all want that is not being manufactured yet but we wish it were.

I start:
A focusing screen (for cameras that accept interchangeable screens eg 1dx and 5d2) with proper split screen focusing aid. This will help me use Zeiss lenses better and focus manually Canon lenses in low light etc.
And, if I could: 24-105 f2.8 IS with good corner sharpness. This will be my ultimate travel lens.

Thank you.
This may not quite impossible judging from Tamron's AF 28-105MM F/2.8 LD Aspherical (IF)

Too expensive, too heavy, too short. But then I am not a pro so its just an amateur's opinion.

Still, the 500mm f/4 IS II is very tempting even for an amateur...  :)  :)  :)

If you shooting with FF, it is almost a no brainer to take 24-70 II over 3 non-L primes

My mini-review of this lens.

http://ramonlperez.tumblr.com/post/33253428138/fast-prime-shoot-out-pt-1-85mm-1-2l-ii-mini-review

+1 Nice practical review.  It was a very good idea to compare the lenses with similar framing. That way the DOF difference is obvious.
