    Hi new here, if I mess this up please let me know mods.

    I bought this lens to use on my e-pl1 as my everyday pocket camera and I love old Pentax stuff. I am using an adapter from ebay seller rainbowimaging.

    These lenses are ridiculously tiny and that is exactly why I bought them despite having a fixed 2.8 aperture.

    ISO 200 1/100 Too close? Probably!:biggrin:

    ISO 1250 1/40
    1175233932_xUiR3-L.

    All photos edited in LR3.

    I think this lens is a fun lens to shoot when you want a certain look. I would not shoot landscapes with it. It produces soft borders with a surprisingly sharp center. The bokeh is certainly Pentax which I like. Focus is smooth and build is solid and light as a feather.

    Did I mention they are TINY even with the pricey adapter.

    Post them if you got them!

    Nostalgia

    My Dad had the Pentax Auto 110 camera when I was around 10 years old. A little plastic Kodak 110 camera was mine, but I got to take pictures with Dad's tiny SLR from time to time and I loved it. I really loved focusing that camera. I learned the basics of taking pictures from my Dad, so receiving a set of Auto 110 lenses from eBay today is a real nostalgia trip.

    I took some photos with the 24mm at the office this afternoon. It's amazing how much the resultant images look like the photos taken by my Dad on 110 film. The narrow depth of field you get from that fixed 2.8 f-stop means there's often something out of focus in the frame and too often it's your subject. The photos have too much contrast and lack color. I thought the small 110 film negative was the culprit, but maybe it's a quality of lens itself.

    I've seen sharp images from this 24mm online, so maybe I got a bad one. The best images I've seen from Auto 110 lenses seem to come from the 18mm. I went out tonight and took some shots with it. I think they have a nice quality.

    Side note -- the 24mm FOV is really, really nice. The Panasonic 20mm 1.7 usually feels lonely and too wide for me, so I rarely use it. The 28mm Canon FD 2.8 is often on my E-P2, and though I like the FOV it feels a little too tight. I think 24mm feels just right for casual use for me.

    I like this one. Taken in a parking lot where sodium vapor lights abound.

    The colors here are fun. Not sure I got the white balance quite right.
    canon_75_0071.

    More boxes.
    canon_75_0081.

    I like the "Close Encounters" space ship effect on the lights -- exaggerated in Aperture
    canon_75_0091.

    I like the lights here.
    canon_75_012.

    This one is cropped a bit.
    canon_75_0111.

    No sure if the out-of-focus-lights thing going on here is anything special with this lens but I like the look of it.

    Nice photos! The rich color saturation, combined with the shallow DOF makes the photos look surreal...

    nice photos. I love a lot of the qualities that these little lenses bring. Your post processing goes well with it, too.

    Great little lens, it's on my camera nearly 24/7 since I got it. If you can pick one up for a good price, get it.

    Side note about the RainbowImaging adapter; it's very stable and focuses just barely past infinity (pretty much what I expect from most adapters). However, the lever you have to push is VERY stiff when you first get it, and almost impossible to reach if you put the 50mm lens on it. If you're planning on swapping lenses in the field bring a Bic pen with you to reach the lever.

    These little lenses are awesome!

    I made my own adapter with iris control from a broken pentax 110 camera that I bought from feebay that also come with 3 lenses.

    diy_pentax110_adapter_zps82cce8e0.

    The adapter came out pretty ghetto looking, but it beats paying 80 bucks for an adapter with iris control. :biggrin:

    The silicone is use to block the outside light and dust from entering the sensor. I will eventually replace the red silicone to black color to make it better looking, and maybe paint the metal part if i'm not lazy... lol The ring and chain that you see there is use to pull/push to control the diaphragm.

    The 18mm and 24mm have vignette, but minimal. I usually carry around the 24mm due to its size. And I find the 50mm lens to be the sharpest.

    Here's quick sharpness test shots for all three (wide open at 400ISO):
    18mm test
    24mm test
    50mm test

    I ended my last, I have three lenses, and today I made tests between 110 and 50mm Pentax-M 1.7 and amazement to 50mm 110 won.

    Has better color and clarity even ...

    I'll make another adapter with iris of more blades.

    I always had Pentax, the last was the K-30, but now I have the Olympus OM-D E-M10.

    I love the E-M10, with Peaking use system all lenses with some success.

    I wish I had the skills to make one of those iris control adapters. I can't find the ones for sale anywhere.

    @dweller@dweller, if you get it and you have the 70mm, let me know what the issue is.

    Thanks,

    My 70mm works well with the iris, the iris must be away 3 to 4 mm of the last rear lens, I think in the case of rjcamera adapter is very near the lens and will not work without any optical angle.

    In the case of my Olympus OM-D E-M10 the iris can be mounted up to the limit the adapter because there is no proximity sensor problem.

    just found this thread, but I was familiar with the ones for the 24mm, 50mm and the 70mm
    I had the opportunity to use the 18mm and even if it does vignette and is much softer on the edges than the 50 and 70, I find it still very usable
