Are you happy with the alpha 700?
I didn't say there was noise, the picture is good
I also thought you used iso 200 for the stars, but on the other hand with a longer exposure at iso 100 you can have the same... But if iso 100 is calculated from the iso 200, it ain't good... Can you check it out for me, or are you absolutely sure of it?
I'm actually very satisfied with the Alpha 700. While the 16-105mm kit lens that I got with it has a few issues (e.g. slightly darkened corners at wide angle and open aperture) but considering the price and the zoom range, it is still a quite good lens. I have not yet found any real weaknesses of the Alpha 700 body though, I'm thoroughly happy with it. The functionality is superb, the handling is easy and straightforward, the Super Steady Shot is outstanding and the LCD monitor is a real diamond.
As for getting the stars into the picture... longer exposure times with lower ISO would have put yet more motion blur into the stars, I didn't want the stars to turn from points into lines any more than necessary.
So i'd go for the Nikon D300 with the 24-120mm VR lens or the Sony Alpha 700 with the Carl Zeiss 16-80... and if needed i'd buy some extra lighting to take with me...
As i've had two Sony's in the past i'd like to go back to the brand... But on the other hand i have 3 nikon lenses, the D300 is weather and dust sealed (the sony is just resistant), slightly better in image quality... But the Sony has the steady shot technology... And that's quite a positive point. Does the camera shoot 5 frames a second with the steadyshot on, and shooting in RAW + jpeg?
Other users who got a "good one" though are very happy with it.
I'm quite satisfied with my 16-105 (with the exceptions mentioned AND it was a lot cheaper).
Concerning the frame rate of the Alpha700...
The Alpha shoots 5 frames a second in all resolutions and all file formats independent of the Steadyshot. You only get an infinite series of shoots (until CF is full) with Jpeg fine or standard though. With Jpeg extra-fine, raw or RAW+Jpeg (which is Jpeg fine), you get 5 frames/sec until the internal buffer is full, after that, the frame rate drops down. How much it is slowed depends on the speed of the CF card. I'm using a 4 GB SanDisk Extreme III card.
The internal buffer of the camera holds...
18 images RAW
25 images cRAW (compressed raw)
12 images RAW+Jpeg or cRAW+Jpeg
16 images Jpeg extra fine
So, with RAW+Jpeg, you get bursts of at least 12 images in a row with 5 frames/sec. With a fast CF, you might perhaps get 1-2 extra. The longest series of images I've shot myself so far was 11 images at full 5 fps, so I can't tell you from experience beyond that.
the glow on the steeple is just magical
great shot!
Watch the stars in the sky, very nice image.
