I would agree with pixmedic--The 85 mm F1.8 G series lens is a decent lens for Bokeh. The 50 mm F1.8 G series WILL auto focus on the D 3200. The word cheap is kind of tricky, since to me a $400 lens is cheap, since I have bought lenses that cost me $4000 or so over the years.
don't mollycoddle them.
a $400 85mm f/1.8G is definitely inexpensive. I woudn't call it cheap...but it's terrific value for money.
I sold mine when I got my 105mm f/1.4E (now that's yowza)
It's cheap in today's parlance.I have owned over 100 Nikkor lenses, and have been a Nikon shooter for 36 years. I'll tell you why it's a cheap lens. It's got a polycarbonate barrel. It's made in China to save Nikon manufacturing costs, it has a cheap, 7-bladed diaphragm, to save manufacturing costs, whereas the older 85/1.8, the low-cost model of its era, had a better, 9-bladed diaphragm. It has a 10-year life expectancy symbol right on the barrel. It focuses somewhat slowly for an AF-S lens. It doesn't even have an Infinity focus stop. The build quality is cheap. The filter thread is 67mm, and it's plastic. It's not a high-end lens. it has an absolutely $hi++y focus distance scale on it, inexcusable for a lens to be used for portraiture or studio work. This is a new-era, cheap, Chinese Nikkor lens. The saving grace is that the lens is sharp and has very minimal, if any, chromatic aberration. As a longtime Nikkor lens buyer and user, this is a cheap lens, in many ways, well below the standard of Nikkors made in the 70's,80's90's,and even the first decade of the 2000's.
But if you say it's not cheap, well, that's an opinion,and you're entitled to that opinion. I'm comparing it to Nikkor lenses from an historical perspective, not Sigmas or Tamrons. THe word "Cheap" has come to mean inexpensive, not just shoddy, but I'm not interested in debating semantics...I'm just recommending this 85/1.8 G because the OP has a D3xxx body, and that requires an AF-S lens, and this is one of the lower-cost AF-S bokeh-producing primes Nikon offers, using the word "bokeh" as the OP intends the word to be used...as in highly-defocused background, and not the
quality of the blur.
Your beloved 105mm f/1.4 is an expensive, high-quality lens. The 200/2 VR is a high-quality, expensive lens. The 70-200mm AF-S E-series zoom is an expensive, high-quality lens.
