According to Google, they are available all over the place, including Amazon.

Thank you for the comments.

I am just trying to decide, if the piggy bank ever fills up again, whether to replace the lens with a modern equivalent.

I do not know if a new version of this lens would be optically better as well as having the benefits of autofocus etc.

I took my 'ancient' Sigma 75-300 APO lens out for a walk this afternoon.

All three are hand held. Nos. 1 & 3 are @ 300mm and are not cropped. No. 2 is @ 135mm and is very slightly cropped.

Having to manually input the focal length for shake reduction and then having to manually focus, means that trees are o.k. to photograph, but hot air balloons and fast moving swans are not so easy

1a, 2a, 3b and 4a for me.

A very nice set.

I am not sure why black & white suits architectural photographs so well.

Back in the 'olden' days, a lot of architectural photography was taken in black & white and it was not merely to save money but to obtain the 'contrasty' effect and the textures.

Do these various bugs just sit there and pose for you or do you have to snatch a shot before they crawl or fly away :

When I first looked at this photograph, I thought it was a couple of stalls and then the mountains / hills behind. It was only when I read your description, that I realised how many stalls in a long line there actually are in the photograph

If you had moved slightly to the left, this might have given a better idea of endless stalls :

Steve,

Amazing - you must be psychic to guess that.

We were sailing along at the bottom end of Chichester Harbour heading East away from Hayling Island Sailing Club, when the International 14 came past us.

Looking back through the records, I see that my wife also took some photographs of Toppers that day, but they were not quite as exciting

As well as 14's there are some scarily fast dinghies in Chi Harbour.

I am waiting to get a good shot of an International Moth sailing on its hydrofoils.

Dirk,

I much prefer this one to your official entry

Certainly an original idea.

Having had the subject matter of "eyes" last week, I thought that "Love is........" was likely to produce some very similar images, hence my entry is love of a hobby.

A very impressive set.

I particularly like the DA 10-17 fisheye shot.

Is architectural photography a specific interest ? Most architects would pay very well for pictures like these of their buildings.
