. The lens tangle of 15-85 and 18-200. I don't know which to choose.

15-85 It's not bad to hang up and shoot the scenery.

But if you want to take portraits, it is still possible to take portraits in the environment. If the background blur effect is pursued, the aperture of this lens may not be enough.

The larger the aperture, the longer the focal length, the farther away the person is from the background and the closer the camera is to the person being photographed, the better the blur effect will be.

15-85 If this lens wants to take a blur effect, it is necessary to use the longest focal length of 85 and the maximum aperture of this focal length of 5.6 to keep the person being photographed away from the background and the camera close to the person being photographed. It is best to take a bust or a headshot, which will have a blur effect, but the effect is also average.

If you want to take a portrait, it is recommended to buy a large aperture fixed focus, such as 50 1.8, which is only a few hundred dollars, and it is also very light, which will definitely meet your requirements.

.

If you must take into account the scenery and portraits, it is estimated that only the top zoom with a constant large aperture will do, but personally, it is a waste of money.

.

Finally, the combination of 15-85+50 1.8 is suggested. Usually 15-85 is hung up to take pictures, and 50 1.8 is very small and can be put in a bag. Change the lens when you need to take a portrait. Actually, it's not that much trouble

There are almost no universal lenses, otherwise everyone will only buy one lens. Why do manufacturers still produce so many lenses?
