Sorry... You are right it was 75-300 with the same specs, I also have to update my equipment page too. For I had mistakenly put it there and that's what confused me. You are right it is 75-300 IS USM. Thanks for all the help as well.

I have looked at the other postings as well but I am not sure about tripod and especially not about sharpness issue in general. My question basically was two-fold. One was with a high shutter speed, would IS in fact work against sharpness or have no effect. The other was the tripod one. For the tripod, I've read that it helps some and some others advise against it. For the other, I am not clear about it yet.

 

Yes there is a 100-300 IS USM f4.5 5.6 lens..

Hi,

 

I set up my tripod at around dusk when it was darkish and put the

Canon 1D Mark II on top. I was using a 100-300 IS USM zoom lens and

was shooting across the Bosphorus body of water to the other side of

the city. I was also using a cable release not to shake the camera.

On average the settings were ISO 100-200, f5.6 to f11, 0.5s to 2s..

 

I took some shot with Image Stabilization ON and some with IS OFF. I

did not do a through test of it but I will try that later. However I

was UNSURE whether the IS OFF was sharper than IS ON. The thing is

since I am using a tripod and a cable release, would IS still

matter? Or iteratively would shutting it off in such a situation

improve sharpness? And even further would shutting IS off in

situations where you can shoot stable at 1/125 or faster help the

sharpness in general too?

 

I am unsure and have not tested my question yet. So I'de be glad to

hear what others have experienced or tested under such conditions.

 

Best Regards and Thanks.

Thank you all.

 

I do not know whichever is possible and how, so I clicked on Contact Us and wrote the same question to the site operators. If they have a preference or a method then maybe one of your suggestions can be pursued. For now, I am still a bit confused..

And I know that Pay Pal does not cover Turkey. But I want to

contribute, increase my quota, increase my alerts, feel better and

finer.. How can I?

Thanks Ken. Your answer leads to another issue: the batteries. Suppose you are out on a photo shoot, whether it is 70 or 150 shots. My battery and usually the backup battery will run out.

 

Anyway, the faster the better but then when you shoot larger megabytes there might not be a very good solution for now. (Of course one tends to compare with celuloid film since those times were faster times..)

I have been shooting with a Nikon Coolpix 5700 for about 1.5 years.

While I like the camera overall, I have two recurring problems.

 

The first is the focusing problem. I find it utterly hard to focus

by turning the dial. Furthermore I can not seem to differntiate

whether this or that is in focus while doing so.

 

The other problem is the write speed. Especially with TIFFs and also

with RAWs, it takes too much time to write with my IBM Microdrive

512MEG.

 

So my conclusion is this: Get a digital SLR next time (hopefully

within a year or a tad bit more) and the focusing issue will be

resolved. Get a newer faster memory card -- but then that might

still be a problem if I want shoot like 8 megapixels or more or

whatever.

 

I would be glad to know if anyone has a different take on the

problem or my suggested solution..

 

Thanks,
