Technical Support / Re: Grand Canyon panoramas
« on: December 29, 2014, 01:56:14 AM »
Here's one I did last October. This is a pano of about 8 portrait-orientation shots done with the 70-200 f/2.8 IS II at 140mm. The point of course being to get maximum detail for a large print (love being able to see the people standing inside the Opera House). The water is a separate single wide angle exposure blended to the building detail (water doesn't stitch too well!).

No special pano gear used. Stitching was done with PS and worked a treat after trialing a few different settings, with a great job on the joins.  The file got up to about 800mb (22K by 6K pixels) at one point and I had to downsize a bit then as it was starting to crash my PC at that size. (And of course downsized further here for posting.)

I did a previous attempt a while ago using the 100L, so I guess that proves it's not too hard to stitch multiple shots at those sorts of focal lengths (can't be too hard if I can do it!).  Having said that, I imagine the Sydney skyline (nice and level) might be easier to deal with than the Grand Canyon will be.

Good luck and Look forward to you posting your results!

Not much snow and ice in Australia in December!  Had to go to New Zealand a couple of weeks ago to get these.

Carrying everything ?!?!?! That's what assistants are for ;)

For you Pros - yes.  But alas I am just the humble amateur!   :'(

I end up using the 70-200 more, but really just because of the flexibility of the range (can't carry everything!). Whenever the 135 does come out though, I'm never disappointed. I'm not really sure what it is, except I'm sure it is NOT the extra stop. I think it is something about the bokeh quality seeming to give the subject more presence in the frame.

70-200 is more versatile, but for a specific shot where around 135mm is the right fov, I'd pick up the 135L every single time.

I just checked mine and it is actually the 10 rather than the 7.  But I do use it to carry exactly the gear you specify, and there is also enough room for an additional small lens (I sometimes carry the 5D3 attached to the 20-70, plus the 70-200, and a Samyang 14mm so I'm covered for most situations.)

I have one of these:

and am very happy with it.  Used for when I want to inconspicuously carry camera with lens attached and one or two other lenses. Doesn't look like a camera bag and the best feature is the huge pad on the shoulder strap which makes it very comfortable to carry for long periods.  Very good quality all round.  There are larger and smaller sizes.

Only criticism would be that there are quite a few pockets inside for carrying bits and pieces and they have flaps at the top of each pocket to secure the contents.  These tend to snag a bit on a reversed lens hood when pulling out the lens. Having said that, i wouldn't want to be without the flaps, so just have to be careful when pulling a lens out.

Lenses / Re: 70-200 2.8II or F4 for Zoo Shoot
« on: November 25, 2014, 08:23:59 PM »
You will not have a need for f/2.8, so why carry that monster around?

Odd and definitive point of view, others have given good reason to go for the 2.8.

As for the latter half of your statement, "monster"? That lens is hardly a monster lens unless you're Monty Burns... ;)

I don't think it's too odd to say you won't need f/2.8 much. Zoo shots are going to be mostly about up close and recording detail and you could lose a lot of that with shallow DOF.  OOF fur not too interesting!

Depends on the zoo of course, but my last zoo trip was about shooting over fences or through glass - not so much through fences. On that trip I used my 400 f/5.6 and the 70-200 f/2.8.  Having checked those shots, there are a lot with the 400mm, but those with the 70-200 tended to be at 200mm and few at wide apertures.

Only exception was a close up (through glass) of one gorilla grooming another - that was at f/3.2 and did benefit from a portraity shallow DOF.  But definitely the exception.

So, I think there's little to be lost with the f/4, and if it allows you to play with a 24mm f/1.4 as well - bonus!

CF design does not seem to provide the best opportunities for fool proofing, but there is some, such as the "thicker" edge on the non-pin side.

Having got home to try for myself, I think there is reasonably adequate protection against improper insertion.  You can get it in rotated 90 degrees, but you still have to push a bit and it certainly does not "feel right". This is exactly the same on my 5D3 as my old 40D, so it would seem to be a very standard set up for Canon. I'd doubt the 7D2 would be different, but if so it would be interesting to know.

Based on that though I'd have to call "operator error" - sorry Klaus

Better design of the CF card could make it easier of course.

In the spirit of internet forums, i wrote without actually trying it myself  ;D , but I think I recall not being able to insert in the 5D3 the wrong way - as others seem to be saying - so the opportunity seems to be there for Canon to do a better job from their side.

(Mind you, I would have tried to insert it with the label towards camera front and the pin edge still pointing towards the pins, not with the pin edge pointing up.  But hey, you can't help bad luck!!)

It is a Japanese company that should know all about Poka-yoke.

Design fault - yes I'd go that far. They certainly should have developed a design to prevent incorrect insertion if reasonably possible.
Warranty? More debatable.

What I don't get is how this focus shift happens.

Wide open and focussed, all the rays passing through all parts of the lens focus (I think this is a pretty sharp lens?) to a sharp point on the sensor plane.  Occlude some of the rays by stopping down the iris and the unoccluded rays seem to have their paths changed so they focus off the sensor plane.

Don't see how that could happen - maybe there's something different going on.  Can soemone educate me on that?

Nice shots nitsujwalker.  How natural is the green colour of the surf?

Here's my effort from the more subdued end of the spectrum.

(BTW "subdued" meaning from a more remote perspective rather than referring to colour - I was just interested to know if the green tint was a local phenomenon.)

Never takes more than a moment for people to realise where this is, but it's certainly not the usual view...

"perfect when it came back"

Do you mean after calibration it needed 0 AFMA on both of the cameras?
