 If you are patient, or lucky, another fairly good alternative for wide angle

 I've heard that's not a bad lens.

 If you are on a tight budget I can suggest the Tokina SL 17mm f/3.5.  It's not 
a spectacular lens but is very good for its price.  It compared favourably 
against the Pentax 15mm, until I did the contrast/flare test.  It even has 
surprisingly low distortion for such a cheap ultrawide.

 I do, but I don't set the "exact" hyperfocal distance according to the lens 
scale.  I tend to keep 1-2 stops in reserve if possible (eg if my desired 
coverage fits within the f/5.6 marks I'll set to f/8 or f/11).

Yep. I do the same thing exactly.

Yes, I do with the SMC 15/3.5. It is the only lens I have which can be
used regularly with this feature :-)

  Hi !

Years ago I bought Zenitar K 16/2,8 - It`s made in Russia and I am very
happy with it.  And it's cheap too - only
1100 EEK  ( 1 $ = 10 EEK  when I purchased it ).

Current Moscow price ~$80.
Last year I heard some rumours about russian people who sell
it in internet (~$150). Rumours was very bad - they catch
buyer's money but not sent lens. Please be careful with such
firms!

I can't advise good way to buy it. But IMHO only help of
your friends or workmates who goes to Russia will be safe
:-( If you will use this way - please write to me and I'll
help to this person where to find it.
But I can't send it to anyone by post :-( Russian post
office works very bad. We just shall lose money or lens.

Two more issue relating to the use of ultra-wides on non-SLR bodies is that it 
is very difficult to predict the relative positions of composition elements when 
working with close/far elements in the one frame since parralax error 
between the taking lens and finder becomes appreciable. Secondly even 
though flare might be no worse in the Heliar at least when using the SLR you 
can see the offending flare before the print/slide is under your nose and take 
measures to limit its effect. I run both SLR and RF ultra-wides and get far 
less surprises using the SLR lens. The flare problem is much more 
pronounced in sunny environs :-)

Any suggestion for ultra-wide angle lens

2001-01-29 Thread Tony Do

Dear all,

I always bring along with my Pentax FA20/f2.8 for taking landscape
photographs. I satified with the results very much. Now, I would like to
buy another ultra-wide angle lens of either 15mm or 17mm, preferably an
automatic and fixed-focus lens. Does anyone have any suggestions or
recommendations for me?

Thanks in advance.

Any suggestion for ultra-wide angle lens

2001-01-29 Thread Joseph Tainter

Many of us have been pleased with, and recommend, the Russian-made
Zenitar 16mm. f2.8 fisheye (available in M42, Pentax K, or Nikon mount).
It is sharp, solid, and inexpensive.

Some users report that recent batches have had coating problems, so buy
one with a warranty from a place you can return it to.

 You might consider this heretical, but have you thought of a
specialised
 rig: Cosina's Bessa L (non-slr body) with their 15mm rectilinar
lens +
 dedicated finder, it should run $-wise perhaps even quite less
than a new A
 15/3.5 from pentax. I read reviews about it telling it's a very
fine lens,
 also would be propably very flare prone and much, much smaller
than the
 pentax 15/3.5. Of course, it's worth trying it out yourself, at
least in
 the shops, or renting. You might not like having to use non-slr
finder and
 scale focusing. OTOH, the lens is in M39, so usable on Leica LTM
bodies if
 you have some and save money off the Bessa L. And they introduced
a 12mm
 rectilinear lens in M39 too!

The Bessa-L with Super-wide Heliar (15mm) combo is probably the most
economical and lightest choice.  It is not any more flare prone than
Pentax 15/3.5 and much less so than the new Tamron 14/2.8.  Don't
worry about scale focusing.  It doesn't matter with such wide
lenses.  DOF is your friend.  One problem all such lenses suffer
from is light fall-off.  The other issue is use of filters.  Pentax
comes with built-in yellow, orange, skylight, and UV.  Tamron and
Sigma has a slot for gelatin filters.  The Ultra-wide Heliar (12mm)
has an optional 77mm filter adapter.  In practical terms that means
that only Ultra-wide Heliar will allow you to use a polarizer (but
it's still a pain).

One more consideration.  When using such wide lenses, it's very
important to keep your camera levelled.  With SLR lenses, I like to
use a grid screen (if your camera allows interchangeable screens).
Voigtlander sells a nifty (but expensive) level which along with
double shoe adapter lets you look at the viewfinder and level
simultaneusly.  For more information on Voigtlander check
http://www.thkphoto.com/catalog/voigtlander.html or Stephen Gandy's
page http://www.cameraquest.com/classics.htm.

 It's just a suggestion to look at non-slr options too. I don't
have any
 _actual_ experience with this lens and camera, so I am only
offering
 suggestion to another option for you to investigate ;)

Just so you don't get the wrong idea, I think that Pentax 15/3.5 is
a truly superb lens that has stood the test of time.  It is the
first mass produced lens with aspherical elements and the first mass
produced rectilinear lens shorter than 18mm.  Yet, I think it is
better than any of recent competitors including Nikon, Canon, Sigma,
and Tamron.

You pays your money and you takes your chance.  As has been the case
for the past 50 years, quality of russian camera equipment varies
incredibly from one sample to another.  Japanese may no longer need
JCII stickers to assure quality, but Russia could still use
something like that.  Caveat emptor.
