I'm intriqued by the range of zoom provided by "in camera" cropping with regards to the Sony H1. Many of the images I've seen at full resolution look absolutely stellar. With other cameras I've used, the digital zoom is absolutely unusable but in the case of the H1, I don't believe this to be the case. I searched the threads to find examples of smartzoom capabilities and have been pleasantly surprised by what I've seen.
From what I understand, when set to 640x480 resolution you can get anywhere from a 1x - 48x zoom. And with the addition of the Sony 1.7x TC, the equivalent of a whopping 81.6x zoom.
I haven't seen any examples of the 48x max smartzoom coupled with the 1.7x teleconverter. Has anyone tried this combination (Tripod mounted) to see what kind of moon closeups could be achieved? Or just regular daylight shots of whatever? I wouldn't expect anyone to even attempt it without a tripod, as any blur could probably be attributed to movement. I don't think the I.S. could keep up with that much effective magnification.
I'm really interested to know what kind of sharpness, detail etc. can be captured with this extreme zoom combination. I realize you're giving up pixels, but just about all posted examples are downsized anyway.
What I'd really like to see are shots at 1x, 12x, 24x, 48x & 48x with 1.7x TC. Tripod mounted would be best. Could anyone with a Sony H1, VCL-dh171758 & tripod post some examples?

If you are zooming in camera (as in, pressing the zoom button while looking at the back of your camera's LCD), you won't be able to save that version.
You will have to open your picture in an image editor and use the crop tool to crop the image to your liking. You can then save that image as a new image. If you don't have an image editor, pixlr.com is a good, free, web-based option.
1. Digital zoom is a part of digital cameras, and camcorders, which helps to crop the entire image, and then digitally enlarge the size of the viewfinder of the portion that is needed to zoom in on
2. Digital zoom crops the image down to a centred area with the same ratio
as the original, and also interpolating the result back up to the pixel
dimensions of the original. this method involves cropping, hence the
resolution and quality is reduced
3. Digital zoom, crops a portion of the image and then enlarges it back to size. And due to this, image quality is reduced in comparison with the original one.
4. Using the digital zoom allows the user to get closer to the subject when the photographer wants to be discreet about taking pictures, like taking a picture of a person in a graduation ceremony.
1. While taking a picture using a Camera to want to get a close shot of the subjectwithout moving physically closer, photographers use the optical zoom.
2. The optical zoom ratio of a digital camera measures how much the lens can actually zoom in to make subjects appear closer. Optical zoom, enlarges a picture while keeping the resolution and sharpness of the picture high.
3. There is no relation between optical zoom and the resolution of the photo, as optical zoom only enlarges the whole image or the subject to a certain range. So image quality only depends upon the mega pixel (MP) of the camera
4. Optical zoom is very useful, while taking a picture of a landscape, or to get a closer view of a subject, without reducing the quality of the entire image, like taking a picture of a Rainbow in the sky.

Once you've framed your shot (zoomed in) and taken the picture. That's it, the picture you've taken is the one in your view finder, and that's the way its kept.
However, if you want to zoom in further, you can using the software you were provided with your camera, you can, you can also zoom in using your camera menu. Once happy you can then save the edited picture. But this time its a digital zoom and it will reduce the resolution. The picture won't look quite as fine. It will be a balance between picture quality and the extent you want to zoom in.
If you have manual focus Minolta lenses, then they are not usable on anything other than other manual focus M35mm Minolta SLR's.
If they have the Minolta autofocus mount then they will physically fit onto any of the current range of Sony Alpha SLR's and also the discontinued Konica Minolta digital SLR's, but there will be some issues:-
there will be a 1.5x magnification factor due to picture cropping caused by the digital image sensor being smaller than a 35mm film frame. As an example, a 70-200mm zoom lens will produce an image equivalent to that of a 105-300mm lens if mounted on a 35mm camera. Lens apertures are not affected by the 1.5 crop factor.
Earlier Minolta AF lenses relied on the camera body providing the autofocus motor. Later Konica-Minolta and Sony models lack this motor so the lens can only be used in manual focus mode.
If you have a later SSM (SuperSonic Motor) equipped lens and want to use it on an Minolta Alpha/Maxxum/Dynax 9 (different model names in different countries), the camera needs a complete additional circuit board which is no longer available.
Later Sony Alpha SLR's have far greater electronic communication with the lenses used. Many Minolta lenses will not be compatible and as Sony don't support legacy products there is no fix.
In short, Minolta MD lenses (manual focus) can't practically be used on any modern digital cameras, and Minolta Alpha (autofocus) lenses will physically fit onto a Sony Alpha digital SLR, but will act as if magnified and may not autofocus or work at all on a Sony SLR. But there's no harm in trying.
Sorry there is no absolutely definitive answer for you, but I hope that you now understand why and that you take a moment to rate my reply.
Sony H1 takes photos at 72 dpi by default. But the picture quality will be good. if you want to convert it to 300dpi open the picture in adobe Photoshop and select image size and change resolution to 300 dpi. but the file size will be very high to up load. if you want to reduce the file size select the image size in adobe photoshop and reduce it according to your requirement. if my solution proves good please rate it. Regards.
Hey needacamera, The range of an optical zoom lens refers to how wide angle to telephoto the lens covers. An example of a 6x optical zoom would be an 18mm-108mm lens, which covers wide angle to telephoto. An example of a 3x zoom lens would be an 18mm-54mm lens, which would provide a capability of capturing images from wide angle to normal views. To calculate the x factor of an optical zoom you would divide the largest number by the smallest number on your zoom. I hope this helps! Sincerely, Allan Go Ahead. Use Us.
