Some of the dimages are small, the 7hi is larger than many 35mm SLRs.
Very few digitals do "true" wide angle: Most people consider 28mm (equivalent) or lower to be wide angle.
Most digitals these days only go down to 35 or 38mm equivalent without adapter lenses, which is OK for casual photography, but does really limit you.
I do a fair amount of real-estate and "oooh, look at that beautiful view" photography, and that was the deciding factor for me on going with the Minolta; It does go down to true wide angle and still manages to zoom in pretty well. With most of the average 35-38 mm minimum(equivalent) focal length "built in" lenses I had to either "stitch" two photos together or use a wide angle add-on lens (which is a hassle and degrades the photo quality) to get a good photo of most of the real estate stuff I do.
If ease of use and macro photography is your primary criteria, go with the Nikon 4500 (or even a 995); it is a good overall camera for just about anything else too. You don't have to spend a lot of time learning the ins & outs of the camera. The "Auto"settings produce remarkable results.
I haven't used one, but the Nikon 5700s are a good all around camera too, and will do decent closeups, but not as good and as "automatically" as the 4500. GREAT zoom range from the built in lens; 35mm - 280mm (equivalent).
Unfortunately the newer Nikons don't use AAs like the 900-950-995 series did.
If you don't mind spending money and having a powerful camera for serious photography, go with the Nikon D100 (It is a true SLR Digital) with a 17-35mm Nikon or Sigma zoom lens for close ups and wide angles, A Nikkor 60mm Macro lens for true macrophotography, and a Sigma 28-200mm (or 28-300mm) zoom lens for everything else. THIS is MY "dream" system, and you can do a good job of whatever kind of situation you run into with the three lenses mentioned.
Although the Canon true SLR digitals are also very good.
It can be kind of confusing talking about lens focal lengths on the digitals, especially when you get into the true SLR interchangable lens ones.- That is why I sometimes use "(equivalent)": The sensor chip size gives a multiplier effect on standard 35mm lenses of 1.5 to 1.7 (depending upon which chip);
So, if you put an actual 28mm-200mm zoom lens on a Nikon D100, you really have a 42-300mm lens equivalent. And a standard 17-35mm zoom would give you a 25-52mm equivalent.
