    What is the angle of view when used with a dSLR with a 1.5x crop factor?

    Can't answer for the 16mm, but the 8mm Peleng on a 1.5x shows the full 180°
    across the long axis.

    I've been using a 8mm Peleng on my E300 and it's a pretty good lens,
    especially for the money. It has the typical ex-soviet build quality (stiff
    focus) but optically seems very good and the diaphram works well. It has a
    "preset" ring to compose wide open then stops down to the preset fstop for
    shooting. On 4/3 it covers the whole frame, sorry not sure what it does on
    other size sensors.

    This was shot is some pretty bad light but still is kinda neat. BTW this
    wasn't "unfished" as some people have assumed it was.

    Maybe it's my eyes or the fact it isn't "unfished" but that doesn't look
    like a wide angle of view.

    Interesting - and very distortion-free.
    The smaller sensor size of the Oly certainly shows up here - to advantage.

    Here are three full-frame shots using the Peleng 8mm on a Pentax 1st:

    (all three reduced to 900px wide, but not cropped at all)

    I'm having a ball with this lens - accepting and working around the
    limitations.
    A little judicious cropping can yield quite respectable results (as your Oly
    shot shows).

    Ah, that's better as I now have a frame of reference since I've used a 28mm
    lens on a 35mm SLR there.

    Just one minor caveat, Greg.
    That shot was taken at one of the "secondary" lookouts, a couple of hundred
    metres down the track from Echo point (hence the cheap fencing).
    Not a *direct* comparison with a shot from the top.

    I think it's pretty close to a "full frame" fisheye on an E300 and this is
    the same focal length olympus is making their fisheye. The trick to
    controlling the distortion is the camera MUST be level, avoid anything with
    straight lines away from the center of the lens and the horizon has to be
    centered in the lens, crop to move it after shooting. I think you could
    crop a really cool shot from that first one you posted.


    This is another fisheye shot, using the ex-soviet 30mm arsat on medium
    format..

    In some ways the "fisheye perspective" isn't as distorted as a normal wide
    angle lens is. With careful use on certain subjects, I almost like the look
    better than you get with a superwide normal type lens. People assume the
    only thing you can get with a fisheye is shots like this.

    BTW here's another fisheye shot done with a 30mm Arsat on medium format.

    Yes, but I get an idea of the angle of view much better than from a place
    I've never been.

    Hi TW,

    If you are looking for a fish-eye lens on a digital camera go for the
    8mm.
    There were a couple of them from a couple of places. KievUSA is a
    really good dealer, and there is a dealer in Canada. Saul at KievUSA
    normally runs a quality check on the stuff he sells. The dealer in
    Canada will arrange for direct shipment from Belaruis. The dealer in
    Canada is a little less money. KievUSA, or is it KeivUSA (I forget
    which way that goes...) normally has the stock on hand, but is more
    money. I almost bought from the dealer in Canada, but found out it was
    a direct shipment from Beleruis. I was not sure if the folks at
    Customs would add money to the shipment. The dealer said they
    wouldn't, but this is our government we are talking about here, so you
    never know what they are going to do.
    If you do a search on Google for the Peleng 8mm Lens the dealers for it
    come up.

    Both of them sounded like they were okay to deal with. I also bought a
    Kiev 88 years ago from Saul at KievUSA. So I had dealt with them
    before.
    They seemed fairly good then. They seem to know a bit about what they
    are selling.

    The other dealer, and I don't remember the name of the other dealer
    did know a bit about the lens, he just had to have it shipped from
    overseas.
    I was not real sure about this.

    As far as the lens, the glass on the Ukrain/Belaruis/Russian lenses is
    really clean glass. These factories are converted soviet arms
    factories. They used to make equipment for the soviet military. When
    the old soviet union fell, they converted the factories to making
    cameras and camera lenses. The Kiev 88 and the lenes for it are really
    high quality. When I found out they had a fish-eye lens for the
    Digital Rebel, I was really happy that I could use this quality of
    glass on this camera. The down side to the Kiev Cameras is the
    mechanics in the cameras. They jam a little bit, and have a 1/30
    second flash sync.

    I have shot some photos with the 8mm fish-eye with the Canon Digital
    Rebel. These were just playing around photos, and not anything really
    great. Send me email at roland [remome] at readytek.net and I can
    email you a couple of them.

    An 8mm lens is going to give you something in the 15mm range if you
    compare it to 35mm, and a 16mm is going to be somewhere close to a 24mm
    lens.

    The 8mm and 16mm only work in the all manual mode on the Canon Digital
    Cameras. The instruction manuals are in Russian, so you have to have a
    little understanding of how the lens works in order to use the lens.

    The markings on the lens are not the same as here, they are a bit
    different.

    That shot looks cropped from the full 180-degree angle of view, probably
    due to the smaller sensor, but it's definitely fisheye, she's not pulling
    a fast one.

    When you get a fisheye shot that doesn't present the "expected" fisheye
    effect, it actually does create a mental illusion that it's not nearly
    as wide of a view as it is -- this is because you're used to the "stretch"
    effect you get in the corners of a rectilinear wide-angle shot, and you
    don't get that in a fisheye. A fisheye projection is more natural and
    less "distorted" than a rectilinear one, to the eye, *if* the shot
    avoids lines that your eyes expect to be straight that aren't straight.

    They are good people.


    That's what I did and was able to get mine in native OM mount which was a
    bonus for me.
    They didn't for me, never had that issue and have bought a BUNCH of stuff
    from eastern europe over the years.

    I can say DO NOT under any circumstance purchase anything from Kievcamera.
    He's not a honest person to deal with.

    That's the key, you have to avoid straight lines or compose in the finder so
    they stay straight and crop later to move the horizon or whatever is
    straight. I actually like fisheye projection when it can be applied this
    way, most people never get to try this because they assume it can only be
    used for "gimicky" shots so they never buy one..
