Photography/Lens P*rn

[RichieH]

Hi Guys,

 

I have had a search for topics relating to this already.. I couldn't find anything, but feel free to send me elsewhere if there is already a thread! I'm sure there are other people that might be interested in this sorta thing. If anyone wants me to do any crazy set-ups/tests, please let me know and I'll post the results.

 

So I took a photo of my colleague earlier.. - excuse the 'I will find you, and I will kill you' pose. He was 85 metres away from me at the time, and this is image is uncropped from a full-frame Canon 6D. 

 

1 second exposure at f/64 - ISO 8000.

 

 

 

 

 

Any ideas on the set up?.. maybe not... so here it is.

 

 

 

1 x Canon EF 800mm f/5.6 L IS USM with 4 stacked 2x Extenders. Effectively a 12800mm f/88 ish L IS, hence the long exposure. Looking through the view finder is a little brighter than it is with the lens cap on.

I hate you already!

 

:cry:

:p

 

Cool kit to play with!

 

I just love "full frame" digital, so anything "serious", I tend to dig out my EOS 1Ds II which just works so beautifully with the dreaded white lenses

You have a fork lift to carry that about? LOL

You'd need a pretty heavyweight tripod to keep that thing still.

Surprisingly, it's not monstrously heavy.. about 6.3-6.5 kilos, or about the same as the older Canon 400mm f/2.8 L IS USM without any extenders on it!

 

Because of the length of it, camera shake was horrendous. We had a 2nd tripod to hold the Camera end and shot on 10 second timer, as it took about that long for the wobble to stop.

 

The 800mm with just one 2x Extender would be able to get you a 'recognisable' photograph of someones face from around a mile away, if you have a cropped sensor camera with decent resolution. At 12800mm, you'd be able to see the rings on Saturn, but the optics aren't good enough for that kind of thing with so many Extenders.

surprised any light at all can get through that stack of glass

You got anything planned or was it just for ****s n giggles

Our glorious Chairman would want one of these to keep tabs on all the members.

Bet the autofocus is struggling with that

Is it true that the fancy top flight lenses are grey / beige to reduce thermal soak and expansion?

[Dibby]

No, colour is just fashion, there are lots of black lenses out there too, camo covers for nature shots.

Canon make there big 'L' series lenses in white so that everyone else knows that they're shooting with a Canon. "If it's big and white it must be a Canon" [or a Sony now] or "Must be expensive". This is good news for thieves, as they know exactly who to target!

 

I actually shoot Nikon, we were just using this as a test.

[clansman]

Only seen one Nikon lens in "white" not sure if it is still available

 

+1 for Nikon too

Who knows one of these days , could be you !

A game of chess, anyone?

 

 

 

 

Have a great weekend!
