Appologies Mike. Very good capture. I use a 50mm macro but find the Sigma & tube better.As for the Nikon 70-200mm f2.8 .. the Sigma isnt half bad.
Taken a couple of days ago with a 23mm extension tube attached.
Taken 3 years ago, same lens with 21mm ext tube.

Thanks.beautiful pictures
The Sigma lens used is the original 70-200 f/2.8 not the newer macro version. It's seen many hundreds of hours use and is my most used lens. I often use the 1.4 TC with it.
Best regards

So feeb, you may have started the longest thread?
Meanwhile, I fly out to Qatar in the morning and am trying to decide what camera to take??
DONE! D700 is bagged with lenses and in the cupboard.
Gripped K7 is going with me with 10-17mm, 16-50mm and my trusty 70-200 Sigma with 1.4TC.

Gary

The shorter lens doesn't make the image the same size on the smaller sensor.
It crops your image, which then needs to be enlarged more to give you the same size as the picture shot with the longer lens on film.
If the lens wasn't very sharp, the additional enlargement would result in a less sharp image.
You need good lenses for small sensors.

Totally agree.The shorter lens doesn't make the image the same size on the smaller sensor.

I can use my 135mm on my K10D or *istD or K7, agreed?I actually think this assumption:

"longer is closer so a 135 on cropped sensor isn't apparently as close as 200mm on FF."
is wrong. I think they are exactly the same."longer is closer so a 135 on cropped sensor isn't apparently as close as 200mm on FF."
But I might be wrong.
I take a photograph of an object at fixed distance, say a bottle on a fence.
I then put a 200mm lens on my MZS and take the same shot, let's assume from a tripod so nothing but lens and body changes.
How does the smaller sensor make the image of the bottle the same as the 200mm image shot on film since both lenses are interchangeable and therefore I assume have the same focus point into the camera body?

FOV would be equivalent but not actual image size on the sensor.
Agreed?
Regards[/quote]Well, of course. The sensor is bigger. This is why a bigger sensor is, all else being equal, capable of higher quality, just as 6x7 is theoretically better than 6x4.5.
But many more people bought 645 cameras than 67 cameras because not all was equal. There are other factors to weigh in the balance, such as cost, size, weight, and lens quality. The smaller the film/sensor size, the more effort manufacturers put into making their lenses sharp.
Some P&S cameras have sharper lenses than you will find on an SLR. They need to!
G[/quote]George, I agree with you but I was meaning that same lenses on same body. i.e. 135mm on a K10D then a 200mm. Actual image of item in focus would be larger. 135mm FOV on smaller sensor may be same as 200mm or so on a FF but for same distance of camera to subject I would expect the 200mm to project a larger focussed subject onto the sensor. I still apply my 35mm rules, longer is closer so a 135 on cropped sensor isn't apparently as close as 200mm on FF. Is this making sense? or I've missed something.

no your right, pentax have produced some brilliant lenses, but not the ones i want unfortunatly
if you can find me a 24-70mm f2.8 pentax lens - plus a 70-200mm f2.8 pentax lens then i will hang around for a bit hows that?
Not taking any sides here (just enjoying the cut and thrust:wink, but the much respected DA*50-135 f2.8 (many peoples' favourite Pentax lens) would be the equivalent of the Nikon 70-200 on an APS-C camera!no your right, pentax have produced some brilliant lenses, but not the ones i want unfortunatly

of course you meant to offend Nathan, if offence was off your list you would not be so damn inconsiderate of other peoples feelings!
Nobody is bullying me about my choice of Pentax, nor forcing my hand to move to Nikon (seriously how did you get that from my posts?)
You have failed to provide any worthy argument, treating me as if i have no talent, no common sense and also ignored all of the points i have brought up about why i am moving
its not your money i am spending, nor is it your kit i am changing so i suggest you step down and stop getting so wound up! Its okay for people to change systems and do what they feel its best - its fine for other people to have a different point of view to you.
I will charge what i want for a days work, again, this doesnt effect you, shouldnt bother you and certainly doesnt give you the right to be such a meany
I will step away from this debate now as i cant handle this trollish attitude
Nathan, you should be ashamed and i think perhaps spend some more time on your people skills as both are needed to be a good photographer.
feeb, sorry to see this thread go sour. I was having a bit of fun yesterday, as I said, I use a D700 as well as other brands. My main kit is Pentax because I grew up with it and at times have felt tied in due to having a lot of Pentax/Pentax fit glass.of course you meant to offend Nathan, if offence was off your list you would not be so damn inconsiderate of other peoples feelings!

That said, I bought a K7 and managed to spoil some flash shots last weekend through not making sure that my settings were correct!
With the exception of the increased weight, you'll love it.
One thing I can say, you won't find a BETTER group out there.
Maybe some true colours have surfaced due to this thread?
Very best wishes and regards.
