Hello!
Thank you very much for taking the time to help!
The question really is whether I need a dslr with which I can change lenses or will my current fixed lens camera suffice. I take photos of mostly family (wife and 3 little kids) and occasional nature.
I have read Ken Rockwell's review of the x100s, which I have, and he says that x100s is perfect for family photos and travel. While I understand that I can crop out unwanted parts of a photo, what I don't understand is whether simply magnifying the wanted part of a photo will be clear and sharp enough. Btw, I do not have experience with photo editing software yet.
In my head, I think I need a zoom lens to get as close as possible to the desired end product that I want and process it minimally, if needed.
Just to be clear, say, for example, I took a picture of the entire length (sideways) of a minivan with my children standing in front of it with my x100s. But, I decide that I want only their faces. Will cropping their faces and simply magnifying the picture work and still be sharp/clear?
Thanks again! I hope I explained it clearly.
This is what I would say no matter the lens. Shoot for the crop, leave headroom. In short every time you crop you loose pixels/information. The advantage of getting a sharp images with some extra room is if you are going to make an enlargement and print it. If you shoot to tight the image gets cropped and you loose parts of the shot causing you to make a smaller print.
A zoom lens for a DLSR or Fuji X like the 55-200 you can do in camera cropping by zooming to eliminate something unwanted. For example take a photo in front of the castle at Disney Land with a 35 mm X100s type camera you have everything in the shot. You an physically walk closer to the subject matter and the castle and person stay the same size, perspective is not changed.
Now use a zoom lens and you can crop out the crowd or something unwanted and then re-crop after wards if you need to fine tune.
*Software, Photoshop Elements is easy to use with some practice, but for a beginner I'd highly suggest the Apple Mac computer. It was designed for video and still use of the bat. iPhoto and iMovie are easy to use.
I'd suggest the web site Lynda.com for online training. Just search what you want to learn it is there. It does cost maybe $25/month on the low end. I know their are other training sites, maybe Kelby as a faint guess if I recall correctly.
