Debbie-

Adding a flash diffuser is cheap. Best of all learn to make use of Bounce Flash. I applaud you motivation to learn more about your flash and what you can do with it.

Hi Debbie, I think that Sarah's ISO 800 photo is a bit misleading as it is not the original but rather a reduced size which will hide some flaws.

Here is the original photo from that Smugmug page, I still can't tell you if this is the full detail or just cropped down to remove distractions, but it's not as large as a full size frame.

I'm not saying that the results are bad, I would just rather you were giving the correct information.

Sarah, when you are giving quality advice/information, can you please post either 100% crops or links to photos that haven't been re-sized so the viewer can see the detail. Incorrect information is often worse than no information at all. http://forums.steves-digicams.com/ge...a-quality.html

Mark-

Here is your requested 100% crop. It still looks pretty clean to me. There was no intent on my part to provide mis-information, please let's be clear on that issue.

Debbie, try to not use your 50mm F1.7 wide open. Use f2 or f2.8 instead. Very few lenses are at their optimum performance at maximum aperture. Take a shot at f1.7 and another at f2.8 and compare them. You will see a difference in sharpness. I have a Sony A200 and have no noise issues at ISO400. I can even get very nice results on 8x10 prints shot at ISO1600. Here's an example of a shot made at ISO1600 with my A200.

Streets: Didn't this shot come from your 100-300 APO lens?

Do the two apply when the OP was looking at short zooms?

At what I guess is a landing speed of about 150 knots for an Embraer ERJ-145, it would have traveled about 1.5 inches during your 1/2000 second shutter speed. So even if you weren't panning, I think you could have gotten away with a longer shutter speed, and been able to use a lower ISO setting.

Oh, and see Why a resized photo is no use in showing camera quality

I think he's trying to show me the quality at ISO 1600 and not the lens quality.

I do see quite a bit of noise in that shot but it is not too bad for being ISO 1600. Also when shooting landscape or objects ISO 1600 wouldnt be as bad as shooting people. I think shooting my kids at ISO 1600 would be disaster.

I was planning on doing exactly what you suggested because I am always shooting wide open and you're right f/2 and above would produce better quality pics.

Of course he was. The direction of the conversation changed and I was still on the lenses.

Sorry about that
