Bigma and birds in flight

[LoveT]

Okay:

I've had a go at doing this (no laughing please ) - I've boosted the saturation a bit (hopefully not too much) and played with rotating the canvas. I'm not sure I've done this right though...

See what you think:

The original:


Rotated plus 45 degrees:


Finally rotated minus 45 degrees:

Hey would you believe it, I own and use one and have for a couple of months, and I genuinely didn't know. I thought it was a brand I hadn't come across before. Why are people calling it that, it says on the box Sigma 50-500 apo ex dg?
Weird!!!!!

Two reasons I can think of - the fact it zooms from 50mm to 500mm, but in my opinion it's because it's a bit of a hefty monster (well, to my scrawny little arms it is - weighs a ton!).

Hi Thea,

The plus 45 degree rotation is quite effective.

Nice pic too.

Most of the Sigma lenses end up with these names, I imagine they originated from some web site, once used they tend to stick.

Another vote for the + 45 degree one Thea. Very nice shot as well

Thats a definite striking difference Thea. The +45 angle. Nice. . . .

i'm fairly sure they originated on the sigma owners forum in the states - but i could be wrong.

tothers in common usage are:

little bigma (170-500, so called cos it is the cheaper but arguably less capable alternative to the bigma - aka the "coffee grinder" on account of the noise it makes when foccusing)
Ossie ( 80-400 OS when it was named that it was the only OS lens in their line up - now that there are others this will probably fall out of usage)
and
Sigmonster (300-800 - the size and weight of this one speak for themselves - its like holding a glass traffic cone)

although not a sigma the other commonly nicknamed lens is the

Pump (Canon 100-400 IS so called because the zoom control slides in and out like a bike pump rather than rotating like virtually every other zoom.)

Really like the +45 deg too! It's very effective and I think an improvement on the original

Thanks all !
