Nikkor 35 mm 1.8 lens?
Hey guys, I'm thinking of buying a good lens that has a good sharpness, bokeh, portrait, landscape, good for the situation low light. Do you think 35 mm 1.8 is a good choice? Can anyone suggest a good target for me.
You will not get all that in one objective – portraits called telephoto lenses, wide angle landscape. These are exact opposites. The closest I could get this into a single standard zoom lens would be f/2.8 (Such as the Nikkor 17-50/2.8 17-55mm/2.8 or Tamron), but still falls short of the usability and capability in low light portrait of a good target, the first rapid. The 35mm/1.8 in my bag, but is one of the lenses that use the least. While its focal length is known as the standard "walkaround" one that I found to be as much of a compromise in terms of focal length and zooms are in image quality or speed. It's too long for most landscape applications, too short for portraits one person. I put one of the top 50 mm more than any day – ideal for portraits and just a little less useful for photographs landscapes of a 35 mm one. Get the 50mm/1.8G 50mm/1.4G or if you have a camera without autofocus motor. If you have an AF motor, you can also consider 50mm/1.8D cheaper.
