One more - a fun one - and my first "sequence shot" at that.  This obstacle was called "Stairway to Heaven":




Some great shots there - had a look at the ones on you're link.


So that's the same rider/horse... and I want to guess a wide angle lens, a tripod, I want to say a wired shutter release, and a likely Photoshop magic playing with layers.

So that's why you needed the speed.  Very nicely done.

Here are some of my favorites from my first Eventing, um, event, over the last few days:

Lenses / Re: IS Versions of the 50mm, 85mm & 135mm Coming? [CR1]
« on: March 10, 2014, 12:54:19 PM »
assuming we get a 135mm f/2L is, What say everyone about the Paint? will it be white or black?  Since this would be a great indoor sports lens perhaps this will be the new "baby white tele"! Perhaps we should be looking for a small white lense during the Souci Olympics! What sport would a 135mm IS be most likely used? Do they have outdoor night events?

Paint it all red for all I care.

As for indoor sports... I could see using it in sports like volleyball or diving if you are allowed to get close enough to the action... but those are obviously summer sports...

Software & Accessories / Re: How many cards?
« on: March 09, 2014, 05:40:56 PM »
hi,

I've recently replaced all my camera gear so i have only one type of card for my 1dx, and that is SanDisk 128GB Extreme Pro i have 4 of them for the stuff i do.

I only use sandisk as i've had problems in the past with lexar cards locking up cameras.


You can wear the cards out so expect a life of 5 years in a professional environment and 10 years for amateur use.

If I used the same card I did ten years ago... it would be a multi media card, mmc, and I want to say it was  mb, but it was probably 32mb... or something ridiculously small like that.  Needless to say... I've not worn out any cards.

It's starting to get nice out... I have a hankering for some long exposure images... I need more lenses so I can make that happen.

The previous poster got to GoPro first, but the cage idea seems sound for working with what you've got.  Layers of bubble wrap on the outside might make for a means of damping the impact of a direct hit.

Jim

did I not to mention that the softball players are 10 year old girls don't have a great deal power

202
Will you share the video if and only if a ball hits the cage?

If I experiment and the cage holds... I'll put the camera in with a filter and I'll throw some balls at the camera with a fisheye lens...

Hi JD.
Thoughts
1 Just how soft is a softball?
2 How heavy is it.
3 How fast is it.
4 Is it not the purpose of a guinea pig cage to keep soft things in not softballs out?  :o
From 2&3 you can work out the energy that the cage needs to absorb to protect the camera.

Cheers Graham.

If I recall force = mass x acceleration squared. 

The mass of a softball is... let's say 8 ounces.  The maximum speed at the 10 and under is maybe 40 miles per hour...

And so I need to convert from stupid American to metric...

Carry the two...

And the answer is... throw softballs at the cage to see if it holds up. 

204
Are people testing write speeds with single or dual cards in place.

It’s always been my understanding that when writing to dual cards using a 5D111 the speed was governed by the SD card. Putting in faster SD cards made no improvement. But this limitation does not apply to the 1Dx.

Can anybody confirm this?

Rob

The way I read it... they are only putting one card into the body... a cf card.

205
Do not know the type of cage you have, but how to operate the camera and make correct framing with the camera inside?

Wide angle and no focus around 15 feet away... And close down the aperture a little. 

I'm not making a film... I recording practice and games to give them feedback.

206
I coach softball and I'd like to be able to tape games & practice and then send clips to the girls and tell them to do better. 

But I was concerned about leaving my body and lens exposed to foul balls. 

Our guinea pig just died so I was thumping about using his 3'x2'x2' cave to house my camera.

I would get a bendy tripod and attach it to the base of the cage.  Attach the camera, hit record, attach the top of the cage and done.

Am I missing anything here?

I'm just going to say screw it and shoot everything at minimum focusing distance and wide open.  I don't care if all of my subjects are in focus... seriously... what do they expect... not to be blurry?

I enjoyed that very much.

If you've heard that then it probably originally came from me, or from the source I originally used.

What happened is that the first outside photographer that got to sample the 35mm f/1.4, was somewhat amateurish and used very weird clarity enhancing technique on his photos (no doubt to make the incredibly sharp lens look even sharper). This made the bokeh transitions look seriously bad, and because Sigma published their photos as the first official samples I and a few other people immediately pointed this out that the bokeh was defective. This was not the case and ever since everyone has praised the bokeh of this lens.

The 35 ART's bokeh is very similar to the 50mm f/1.2L, contrasty yet buttery. The 35L has bokeh that's closer to the 85 L II, which is very flat on the other hand.

The main problems with the Sigma are distortion and purple fringing.

I haven't played with the 35 yet... so I'll hold echoing that opinion until I play with one.  For what it is worth... I dont' think I originally heard it from you... It was in regards to a conversation I was having where I was complaining about the 50mm canon options.  I said something like... the sigma 35 is sharp... why can't the the canon 50's be... and then someone said that the 35's bokeh was not smooth and delicious the way the 50mm L's is...

but that's a conversation for another day.

If you really want to buy something, try a Sony A7r + adapter and have fun seeing what your Canon lenses can do on a higher resolution sensor.  And if that's not enough, get the Sony/Zeiss 55mm 1.8 and enjoy some pretty remarkable resolution/sharpness etc.  Those who claim to disapprove of pixel-peeping don't know what they're missing (or perhaps they do)....

Nope.  I have a sony tv... a sony playstation 3, & a sony 5.1 audio system.  I think that's about it until I get the Sony playstation 4.  I'm really happy with my 5D mkiii.

I'm not sure if you are thinking that I claimed or implied that "the context of the article would contradict anything said in this thread". Au contraire what I was saying was that some people don't seem to grasp this simple relationship, the subject of the article I linked to. It is rather counter intuitive and many people have not grasped the link. I thought the article was a good clear explanation that restricted itself to a relevant and concise description, without going of at a tangent into irrelevant areas as so many do. It was jdramirez who questioned what someone had said. (and pleased don't read that to be a criticism of jdramirez from my point of view he was just asking for clarification and there is nothing wrong with that.)

I'm still wrapping my head around all of this.  I was under the impression that dof was dictated by aperture, distance to your subject, and focal length... and then there is the full frame v. crop... where full frame has a slightly more dof field all things being equal... but if focal length isn't a factor... well...

And then I was reading something about shooting video a few months back... and they made a point that instead of shooting at 35 or 40mm on a zoom lens... use the larger depth of field when @ 24mm and you don't have to worry about dof as much.

But if I'm framing my subjects identically... then that advice is flawed. 

And there are so many (what feels like differing opinions) opinions from people whose opinions I respect... that it is hard to say what is or is not accurate.  Do I trust this person... or this person... or neither...

I'm just going to say screw it and shoot everything at minimum focusing distance and wide open.  I don't care if all of my subjects are in focus... seriously... what do they expect... not to be blurry?
