If you are wanting to do table-top photography, most small cameras can do a good job of that.
It has more to do with good lighting and a tripod.
A light box is very handy for small items.
Certain camera features are desirable:
Manual Controls let you control the Depth of Field (DOF) by controlling the aperture setting.
This is important when photographing small three-dimensional items.
Spot Focus lets you focus on a place on the object instead just of the object itself.
This also helps with DOF.
A swivel LCD is helpful when you are working at an awkward angle.
You also mentioned that you are interested in portraits.
That brings up the subject of DOF again if you want blurred backgrounds behind the person.
So you need to understand how Depth of Field (DOF) works so that you can control it.
I can't help you with buying on eBay, as I have never done that.
Hi there, I will need a camera which takes great photos of objects, and decent/good photos of people. I prefer something slim and all on the same plane (just because others are bulky). Either AA rechargeable or a built in battery as long as it does not require only a usb to charge.
-It's nice to have an image stabilizer, but I prefer good quality images of objects above all. I have two sizes of tripods.
I will be using ebay- just because even the $400 cameras go for $35 (the Nikon COOLPIX 775 Digital Camera goes for around $30 and rumors are that the store price was or is $400. There is a IXUS 950 going for $40 right now and i've used it for many many years),
so please -if each person can- recommend me more than one and i'll check them all out. Please dont recommend me something that might go on ebay for more than $60 =P I know money=quality but just looking for something for this situation, so try your best 'shot'.
I really am appreciative of this help~! (I just would like to get a few camera models to look into please :3 thanks much~!)
