Following on from the 9 to 14mm lens thread I remembered I had a couple of pictures taken at 12mm and 7mm. The pictures were not taken to demonstrate anything and so they may be from slightly different positions but they do give an idea of the extra field of view of the 7mm.

Wow that looks impressive.

If you have the 7-14, could you do a couple of shots at 7mm and 9mm on a tripod, and overlay. I think people would like to see what they are getting.

Cheers,

Here's a link to the 'standard' image showing the comparative field of view for Olympus lenses:

As you can see, the 2mm between 9mm and 7mm makes quite a big difference!

Thanks Jim,

I saw this before doing mine, but as the 9mm and 14mm were buried further in, I couldn't really tell. That's why I did mine, and with the perspective change.

The 9mm on this diagram is next to the final 7mm on the image, so it is easier to tell that there is a real difference. I wish I had the money to have got the 7-14mm! :)

In angle of view as well as price! :D

LOL :D

I think the 9-18mm is great already, but I need time to go out and shoot more/learn with it!

That's really useful *chr

The other aspect or benefit of the wide angle is how it can dramatically change perspective.

If one keeps the main subject of the image at full size then the background will be dramatically smaller than in a shot with a normal lens with the subject taking up the same area on the image.


Should the rain ever stop and the clouds lift I will try and get some pics to illustrate this - if no one else posts some samples.

In the mean time check out the two articles here

THe second article is linked to at the end of the Wrotniak article,

Do you mean this?

First image at 18mm:

Then moved closer to keep the main subject the same size and shot at 9mm:

I think this illustrates your point: that the background shows a considerably larger area. I'm not sure which I prefer, but the effect is clear! :)

Yes that is what I mean - obvioously the subject will determine the exact focal length you wil choose to get the emphasis that you are aiming for.

Apologies for reraising this thread - but here are two images showing the effect of the 7-14mm to obtain an exaggerated sense of distance, each head is approximately the same size and each casting is approximately 5 foot tall. They were about two foot away from each other.
