Wonderful point of view and mix of definitive edges with soft content.
I find it different enough to take the time to study.

The composition works VERY well. The colours are cool and that thin line draws attention.

I will take that
When I saw that price Mike, I felt a bit sick having paid good money for mine.

Gareth, had you been based in Brooklyn, this was a typical bait and switch exercise.

I am sure your kit will go to deserving users.

Good luck with the sales and best regards

Gary

You're right about that but Greynolds wants to have the subject appear larger relative to the pixelsize I believe.
It's not an issue Stefan,

No arguments Gareth,

The OP got side tracked. I have not helped the situation.

We will all go on and do what we like doing best within this forum, open discussion, learning from others, putting our point of view, either through experience or theory and always respecting one another.

Have a great Bank Holiday Weekend (UK) and a great weekend else where.

So you're going to rent a 500mm or 600mm ?
Or else you can do with a lower pixel count Pentax camera with a 300mm
Stefan,

A 300mm lens won't do what a 500 or 600 can do irrespective of what is behind the lens.

"Pulling power" comes down to numbers as far as focal length is concerned.

There is no cheat factor or alternative, unfortunately.

I have just noticed that the Exif data for the Dx shot has an extra line under Focal length.

It is:

Digital Zoom: 1.530x

Whats the Megapixel size on the D700 when in Dx mode compared to Fx?
Mike,

I have just looked at the image dimensions on the card.

Fx is 4526x2832 so roughly 12.8MP

Dx is 2784x1848 so roughly 5.1MP (which is just shy of my istD).

Once film takes off again, some one will regret not buying this piece of modern art....

If this does not sell, we are all doomed...

Just shot two images on the D700. Both at 200mm and ISO 2000 (due to poor light).

Same subject within time taken to change from Fx to Dx. Both sized to 800 pixels from full size originals (no manual crop).

The subject in the Dx image is larger than the Fx image due to "upsizing". Same sensor, camera and lens. So projected image size on sensor did NOT change.

Cannot post here due to being Nikon images but have given links.

I agree Mike, it's down to enlarging the narrower FOV to bring it up to a "normal viewing size. Hence the 1:1 statement.

I may have said this before when discussed, changing a sensor size behind a 200mm (or any other size) lens, does not change the focal length or magnification factor of that lens.

Its odd that the above images are all "image subject" complete?

I would have expected that an image taken from the same point with the same lens on different size sensors would result in some subject cropping or reduced size.

Does that sound logical?

I'll shoot both, tomorrow on a K7 and post images. Same aperture and shutter speed. Haven't used the 15mm for some time.

OK, two quick shots.

K7 set at ISO 100 and 1/60th sec. Manual.

Both lenses were set at f/8. Central focus point used until beep heard. Shutter cable released. Only adjustments (levels-minor black adjustment and sharpened to 100% @ 0.3). No colour adjustments.
