    Lens Identification

    HI, I picked up this lens from a charity shop (thrift store) the other day for 10 Danish Kroner or $1.50/£1.20 . At first I thought it was some kind of CCTV lens I could use with an adapter on my Pentax Q or Fuji camera but I can find nothing about it. It is called Coyal f3.5 and looks like...

    Leica Long story and a question re lens selection in the menu.

    I mentioned previously that I'm sending my M10 for a warranty claim to adjust the light meter - it seems to be overexposing by about 1-2 stops. I've had this camera for over a year, and during the early months I was also messing about with a Black Pro-Mist filter. I noticed from the...

    Sony 3rd party lens questions (distortion correction)

    Does anybody have experience with fully electronic 3rd party lens on Sony bodies, if a lens like for example the Sigma 30 1.4, provides embedded correction profile, does the live view apply distortion correction? I'm not asking about jpg or raw corrections, but the live view as that will affect...

    Lens physics

    In my seemingly never-ending quest for "The One Camera to Rule Them All", I have bought, sold, traded, rented, and researched a lot of different cameras. Some of you have been producing some very nice images from the RX100 line of cameras, but I'm convinced those cameras would be much too small...

    A7 III with a really old lens

    Panasonic LX3 Lens Distortion

    Here's what Panasonic has to say about the LX3 lens: Here's an uncropped, resized in-camera JPEG at 24mm equivalent, 16:9 aspect ratio with my D-LUX 4 (same lens as LX3): Here's the same photo processed from RAW without correction of distortion: It takes about a +15 distortion adjustment...

    Fuji Fuji XF16-80mm f/4 OIS lens leaked

    Fuji will announce two new lenses tomorrow... - mirrorlessrumors Could be interesting. I was disappointed in the XF 18-135 - did not like the IQ from it at all. I could see this lens in its field of view being very useful. I hope that Fuji got this one right and I could see the 18-55 going...

    Leica How to properly clean a vintage lens?

    I know that the best is not to clean them, but how to clean an old lens when we have fingerprints and the glass or the coating is very soft? Summar, Summitar, Jupiters... I use a cotton swab with some cleaning fluid for lenses, but I do not know if it is the best option.

    Fuji (Sigh) Another lens purchase on the horizon

    I made the mistake of wandering into the electrical store in Heathrow last week, assuming that they wouldn't have anything interesting. Unfortunately, they had a 100-400... It was big and heavy but not as much as I thought it would be. The OIS works really well and I want to start getting...

    Sigma The Sigma 15-30mm EX DG Lens - Revisiting modern vintage glass!

    Lately I've been researching all the various wide angle lenses you can get for a modern DSLR. After shooting mirrorless for awhile and witnessing the smallness and simplicity of compact M-mount wide angle glass, especially the Voigtlander 15mm f/4.5 Heliar lens, I've been searching for a DSLR...

    Sony Showcase My first shots with the 7Artisans 35mm f/2.0 + A7III!

    I've been searching for a cheap replacement for my Voigtlander 40mm 1.4 Nokton MC. While it was very sharp in the center, the field curvature softness was really starting to bug me due to the thick sensor stack of the Sony bodies. I've been looking at other alternatives such as the Voigtlander...

    Fuji Showcase 7artisans 55mm f/1.4 Lens for Fuji

    To be honest I'm not sure how I tripped on this lens. But after using it for a few days I'm very glad I did. This lens retails for $119. and not unlike 7a's 25mm f1.8, ($79.), it seems to offer some very serious image quality for an exceptional price. The build quality appears to be very...

    Sony New a6000 owner

    As per my thread on the UK Photography Show, I now have an a6000 with the 16-50 kit lens. I've also got an adapter to fit my old Russian Jupiter-8 50mm f2 lens so that should be fun! First couple of test shots below. Nothing fancy but the 16-50 gets closer than I thought it would, and seems...

    Leica Carl Zeiss Jena 5cm f1,5 Serial Number Check

    Hello, I have a wartime CZJ Sonnar 5cm f1,5 in Leica Thread Mount serial # 2870001 which seems to date it approx. from 1942. I need advice on how to unscrew the optic module to check for matching serial numbers and perhaps determine it's authenticity. I am loathe to dismantle/damage the lens due...
