Getting your camera taken in for its 5,000 mile service and oil change (just kidding) is a habitual need for heavy users of their photography equipment. A camera that is so old finding service or parts is impossible can’t be feasible. Aftermarket parts, storage, and replacement battery media can only last so long.
Shopping for a camera should incorporate all the uses you have for it and add to your scope and performance in delivery of micro stock images. Take some materials or items with you and test the camera in a trial setting. Think about the best complement to the camera your currently own, not a match to it or an update.
The resultant image had a shutter freeze blur that appears artistic to some people and could look very attractive in a framed portrait. I was switching between museum and micro settings because I wanted to see how much flash the micro setting generated at 5X digital intensity into the field. the varying image files to choose from each had benefits and drawbacks. Experience with the finished cropped and reduced file result helped me choose the right one.
Marketing images takes flexibility. The flexibility of providing different types of images under different circumstances comes in part from the camera. Limitations will be felt sharply sooner rather than later. Borrowing cameras and trying them out is advised.
I saw easily that features like a video screen, megapixels, and battery type were factors of price. I knew that memory storage multipled in density per megapixel, which was some of the ten megapixel cameras were seriously on sale. I also knew that battery power decayed faster, which meant long term photo snapping might be more practical with a smaller capability lens.
