Something that s "professionally looking" isn t.
You choose a lens to match what you re shooting it with. Look at focal lengths and then speed.
That 25mm is a normal/standard lens for the G7. It can be used to shoot almost anything. What it can t do is take landscapes or large group shots. It can t make far subjects look near too. For the former, you need a wide angle lens, lesser than 25mm, the wider, the more of the scene you see. For the latter you need a telephoto lens, higher than 25mm, the higher, the nearer or larger the subject will be.
At f/1.8, that 25mm is quite fast. The larger the aperture size (the smaller the f/number), the faster you can set the shutter speed, the better you can freeze action, the more you can shoot in lower lighting conditions, and the easier you can blur backgrounds. The lower that f/number is however, the higher the price of the lens shall be.
Those who demand the highest optical quality go for single focal length lenses. They don t think about zoom at all. When they move around, they simply are just "framing the subject" or "composing" the shot. The highest optical quality is best attained when zoom is least which in this case is none.
Admittedly, there are shooting scenarios where you need a versatile lens (one that zooms) like when shooting most sports and photojournalism. These are the times when you can t move from your spot so you lens the lens do the walking for you. In these cases, you get a lens with a focal length range that is most useful to you.
So what s the best lens to get? The answer is "It s all up to you".
