Something to ponder!
This video shows it done by a photographer with different lenses. Not as good as the racing, but might help some people. Notice that on the Tele shots (200mm) the crowd behind don't look to have much room. You can't achieve that by enlarging a WA shot. http://www.youtube.com/watch?v=7Fzh9eQD...

There seems little point in taking this topic any further. It's beyond the scope of this forum. I've just looked again at the Photozone article and it just about covers everything and is spot on. They (Photozone) are a Team of at least 3 professional people who are friendly with quite a lot o...

Right, this is my last attempt. Going back to this WA photo It's obvious due to the extreme WA distortion you can't crop it and get a Tele view. If you crop off just a hand, the fingers are bigger than the thumb. You could also use a smaller cropped format and capture just say the hand an...

That's a nice magicians trick Tony :mrgreen: You've magnified one of them :shock: The one John posted has also been magnified :shock: John's also has very little info in the 3rd dimension, (no depth) which makes it hard to tell what lens it was taken with. I could use the same trick to prove ...

I agree John :wink: although I am surprised that considering you once used film you seem to have forgotten that to appreciate perspective such as a life size 135mm portrait you have to stand at the same distance that it was taken from or it will look flat. If you enlarge twice as big you have to...

No doubt you will all be happy when sensors become so good that you will only need 1 lens say a 15mm and just crop every shot to match Normal and Tele lenses :mrgreen: -- And that, if you read back to the beginning, was exactly the point I was bringing up. I for one am finding my self more and...

Algi, go back to the original post which is about crop sensors vs full frame. The point is if you crop a 16mm lens to give the same angle of view as a 24mm lens, as happens on a crop sensor camera, the results will give exactly the same perspective. Numerous examples posted in this thread prove this...

What lens are you using for studio portraiture ?
Ralph, your shots illustrate why opening up the aperture to throw the backdrop out of focus (and to be fair moving your subject away from the backdrop) might be a good idea. Fast lenses aren't just useful for low light, and just because there is plenty of light in a studio doesn't mean we should ...

What lens are you using for studio portraiture ?
Whilst you talking about studio portraiture a Golden Rule is don't try FULL LENGTH shots with a WA, especially with women either clothed or wearing bikinis. The distortion between body an legs is just too great. You have to get well back. No point even thinking about it in a small studio. Ral...

Polariser choice for the DA 12-24 f/4
I am on a learning curve with this lens and have noticed the varying effect of a polariser across the frame. I'm embarrassed, the reason seems so obvious now that Steve and John have commented on it. A Skylight may be more useful than a CPL. I have an image with a massive blue colour cast taken w...

Microsoft ICE Panoramic Software
Yes, I use it occasionally. It works very well for me. I spent several hours at the Trafford Centre a couple of weeks back. I was dim enough not to take anything wider than a DA 35 f/2.4. This is three (hand-held) shots stitched together with Microsoft ICE. Andrew

I am a new to this hobby and so this question may sound a bit daft.Is there a way I can calculate how far a subject is away( bird/wildlife )and also what distance would I expect to get an in focus photo at 400mm on a Bigma.Sorry if it is a daft question. Graham

Distances
Most lenses have distances marked on them, so focus on something and read off the distance on the lens. The second part is called depth of field. At a given distance there will be things in focus in front of and behind where you have focused. A large aperture (small f number) will have very shall...

Thank`s for that John.Am I right in thinking that if I focus on a certain point the subject could become more in focus if I change the f stop (in AV mode obviously). Graham

In a way, yes, assuming the subject isn't a flat one. If it's flat, then it's all at the same distance so that would be in focus completely at any aperture. If it has depth (more usual) the as you stop down to smaller apertures more of the subject will be sharp.
