Your subject(s) wasn't in motion (in three dimensions, I might add!)! :-) But I do agree that focus is the real challenge. Manually focusing on a moving subject with the fov of a 900mm lens is very difficult. Especially since the focus ring of the Sigma only moves about 1/4 turn when manually focusing. I use just the thumb of my left hand to turn it since it is so sensitive. PS: I was wondering what the 100% crop would be. you disappoint me, Mr. Studdert. -- Christian [EMAIL PROTECTED]

Show off! I was wondering there what you'd choose as your crop. ;-/ (Do all the women in Australia have that many freckles?)

RE: Hand holding long lenses (Was PESO - Coming in for a landing)
A good old rule of thumb says for 900mm you'll need at least 1/900 sec. (for 35mm film). I guess this applies for APS format if you muliply by the crop factor of 1.5? I can hand hold 300mm F4 lens, but actually - I'd rather use a monopod or a tripod. When I use my M* 4/300mm + an F 1.7 AF Adapter I get 510mm - on the *ist D this equals 765mm. I know I could NEVER hand hold this - I even have to use the timer to get shots like that sharp at 1/100 sec. on a sturdy tripod! I do think Robs shots are quite impressive! 340mm and 1/800 sec. can produce a "not shaken" image on the APS-C sized sensor (The Rule of Thumb would say "at least" 200 x 1.7 x 1.5 = that is 1/510sec.

And I drink just few cups of tea every day. Hi Boris, I'm not speaking for Christian but I think that you will find that practice helps a lot and from my experience after you have got good hand holding techniques well practised focus will be your worst enemy. I was shooting a lot over the weekend with my FA200/2.8 and 1.7TC on the *ist D always hand held and there were very few images which were ruined by camera shake particularly those shot at 1/800th or faster. The following shot was made using the lens combo above at a shutter speed of 1/800 @ f7.1 ISO200 http://home.swiftdsl.com.au/~distudio/temp/IMGP8884.jpg FF shot scaled to 25% http://home.swiftdsl.com.au/~distudio/temp/IMGP8884crop.jpg 100% crop Cheers, Rob Studdert HURSTVILLE AUSTRALIA Tel +61-2-9554-4110 UTC(GMT) +10 Hours [EMAIL PROTECTED] http://members.ozemail.com.au/~distudio/publications/ Pentax user since 1986, PDMLer since 1998

Hi Jens, Yes I think to make all things equal you have to consider the crop factor since the image will need to be magnified in order to achieve the same print size for the same lens on a 35mm body. > I can hand hold 300mm F4 lens, but actually - I'd rather use a monopod or a > tripod.

I would have a go but the problem is that I'd be wanting to stop the lens down to at least f5.6 to obtain reasonable optical sharpness so you could only use it in really good light, fortunately something we have an abundance of here.
