Default The most portable 400mm lens?

I'm very happy with my Vivitar combination. A 200mm f3.5 lens with a 2X TC. Quite sharp images with no obvious CA. Apart from mirror lenses, is there a smaller 400mm lens (combination)?

Try this one. Not much bigger than your 200mm if you get the TX or T4 version.

Hi Dawg, thats a very nice 400mm prime but it looks longer than my Viv combo, which with both lens caps is 16cms in length (15cms or 6 inches without lens caps).
Cheers

bb2,
the viv 200/3.5 is a great lens..for the price.
there are no 400mm lenses that fit your need..
you're asking for too much.
a 400mm will cost 250usd- ????
some of the vivitars 400mm will fit you're need but not at the size you want.. the vivs tho are a toss up at getting a good copy..
you seem to be blowing the high lights in the pic.. probably because i'm on a cheap laptop

Hi Roy
Just a quick test shot. The dog likes to soak up the sun. Yes the highlights are blown here, but I think the picture otherwise demonstrates the reasonable qualities of this small 400mm combo.
cheers

I have tried various combination to get to 400mm. I researched the options in Searching 400mm MF prime


picture of Soligor 200mm f/2.8 next to Komine 200mm f/3.5
both are very small and lightweight, close to Pentax M 200mm f/4.0


1. Soligor 200mm f/2.8 plus Kiron 2x matched multiplier
* very inexpensive to get
* both in M42 mount
* very small and light, hand-holdable for sure
* not extremely sharp wide open though
* color and contrast pretty decent
* pretty decent bokeh


2. Vivitar 200mm f/3.5 in K mount from Komine + Pentax F-1.7x AFA adapter
* also very inexpensive to get
* color and contrast pretty decent like the M42 combination
* need to use green button for stop-down
* some PF/CA noted in wide open shots, not major
* With K mount, the f-1.7x adapter turns the MF into partial AF


3. Tokina 400mm SD f/5.6 with 'A'
* still lightweight as compared to others
* hand-holdable
* don't need TC
* a bit more expensive
* sharpness is not the best wide open, but very decent in f/7.1 and f/8.0

Thanks,
Hin
