C-mount to m43 adapters (2) Fri, 27 Jan 2012 17:25:08 -0700 Alex 2124@/talks/discussions ... what are your experiences with c-mount adapters? How do you adjust your c-mount lenses to have proper focus to infinity? I thought I just have to buy a precisely machined adapter and all those lenses will fit just how they should. Now I own about 5 different c-mount adapters (latest is the METABONES adapter) and non of them seam to match the required flange back. Do you have to loosen all those tiny screws on the lens and adjust it to your camera/adapter??

good info I googled:

Inside if found an Helios 44M 58/2 the lens seems to be in perfect condition apart from the aperture blades do not seem to make a perfect circle. Glass is perfect condition, It also came with a couple of interesting filters a Hoya center spot clear filter an a softener B! Wonder what these will look like in video mode. Has anyone ever used these? Anyways i'm looking to get an adapter so i can test it out. Suggestions please? Just another thing whilst browsing for that lens it seems like most of them go to aperture f16 mine is f22 is that something special or rare? Okay this is what i'm looking at

Ultimate Line 84.5mm and 100mm ND Filters Thu, 15 Mar 2018 14:32:42 -0600 Vitaliy_Kiselev 19212@/talks/discussions

European company 84.5mm / 100mm camera filters presents new series of photographic filters called ULTIMATE LINE made of high quality organic glass CR-39.


Ultimate line are 100mm wide Neutral density camera filters fully compatible with all other standard filter systems / holders of various brands. Filters are hand made in EU and designed mainly for outdoor use (landscape photography, architecture, nature etc.)

84.5mm / 100mm camera filters company describes why use of graduated neutral density filters is often necessary when shooting outdoors also in digital age: “The human eye has a much greater dynamic range than photographic film or CCD/CMOS digital sensor (dynamic range means the ability to visualize a wide range from darkest to lightest shades of the light).

Because this fact, often happens that high dynamic scene that we see by human eye lost most of its dynamic range after shooting with digital camera, for example dramatic textured clouds are on the digital photo visible only as a large white area, in photographic terminology: "over-exposed area". Upper part of the image is very light and lower part is very dark.

This negative fact is present because digital sensor or film can not record images with a large dynamic range such as a human eye. Due to this, a photograph taken outside (outdoor) is sometimes useless when a filter is not used. And that is why almost all outdoor photographers (landscape, architecture or nature photographers) uses filters so-called gradual ND filters (Neutral density filters).

The neutral density filter is grey colored filter which reduces amount of light passing through a filter and it neutralizes darker upper part of image without affecting its color tone (neutrality). The result is often stunning - "blow" of the sky will disappear, the sky and cloud structure becomes visible, three-dimensional lattice, while the very bottom (landscape) remain ideal exposed (not over exposed, not dark). Moreover, the effect is very natural and the use of the filter is not noticeable.”

Material used for production of filters is Grade A highest quality CR-39 often called “organic glass” from USA. This material is often used for cockpits of military airplanes, lightweight dioptric glasses and by best producers of square camera filters. It has high resistivity and superior optical parameters like refractive index 1.501 and Abbe number 58.

84.5mm / 100mm camera filters won various awards including Digifoto Pro and Ephoto golden medals for its neutrality and optical quality and are used by most famous photographers like James Grant, Bart Heirwig etc.

Filters can be purchased by network of worldwide dealer or directly from

Shipping worldwide. Prices of filters starting at 49.95 Eur (you can apply coupon code FLASHSALE25 for additional 25% time-limited discount)

Irix Edge 100 filter system Fri, 20 Oct 2017 13:38:59 -0600 Vitaliy_Kiselev 18036@/talks/discussions

The TH Swiss company would like to announce the expansion of its range of Irix accessories with the Edge 100 series filter system. Among new products, there will be a versatile holder – the IFH-100 - with dedicated adapters and a wide choice of 100x100mm and 100x150mm filters.


The Irix Edge IFH-100 filter holder

The Irix IFH-100 is a universal filter holder designed for size 100mm filters. Its lightweight compact construction and bayonet adapter are created especially for the Irix 15mm f/2.4 lens, allowing the use of two filters at the same time without any vignetting effect. The construction of the filter holder base on the removable adapters allows for quick and easily attachment to the lens, along with free rotation around the optical axis when using the graduated or polarizing filters.

The ability to use removable adapters with thread diameters from 67mm to 82mm means that the holder can be used with lenses produced by Irix in the future, along with other brands. Each adapter has an additional thread for attaching the cap to the lens.

The filter holder is made of an aluminium alloy, which guarantees the high strength and stiffness of its structure. This has enabled to get an extremely compact size while keeping wide functionality, along with an aesthetic design together with the whole Irix product line. It is worth mentioning that the IFH-100 is the lightest holder of its class. The front surface of the filter holder is covered with a light-absorbing velvet fabric that blocks access to the side light, what is especially important when using high density optical ND filters.

The Irix Edge 100 filters

With the introduction of the IFH-100 filter holder, the Edge 100 series filters will also be available in two formats. The first, size 100x150, will contain gradual filters with a soft and hard transition, and also a reversed gradual filter dedicated to taking pictures of sunrises and sunsets. These rectangular filters will be available in ND4, ND8 and ND16 versions. In the square format, Neutral Density filters with densities ND32, ND128, ND1000, ND1000K will be available for the 100x100mm, along with a polarizing filter. There are future plans by the manufacturer to introduce filters which reduce light pollution.

Edge 100 series filters have a thickness of 2mm and are made from high quality optical glass which is also used in the production of the optical elements in lenses. Filters are coated on both sides with an anti-reflective nano-coating to keep high contrast and natural colours in pictures. The additional water and oil repellent coating also ensures easy cleaning of the surface.


The premiere at Photo Plus Expo 2017

The Edge series will be available at the Irix booth (No.929) during the Photo Plus Expo in New York City on October 26-28, 2017.

The full range of new Irix Edge accessories, along with pricing and availability information, will be published in the near future.

Lens Turbo II (FD to M43) + FD 50mm 1.4 - cant mount lense so aperture works Mon, 06 Mar 2017 02:40:43 -0700 baschmir 16548@/talks/discussions Hi dear forum,

I just received my Lens Turbo II and tried to mount my FD 50mm 1.4 but I cant make the aperture work. I bring the red dot of the lens to the yellow dot of the adapter and twist it towards the red dot (so red dot of adapter and lens match up). While I do that i can feel that the metal screw of the adapter is moving the aperture hock (dont know how that is called), but when the red dots are lined up so the entire lens should fit into the adapter to move again in the other direction its not possible because where the screw is placed the lens pops out a bit and is not fitting into the adapter. if I lift the lens a bit and put it back it fits but the metal aperture hock is not in place anymore and when i screw the lens on the aperture ring is not functioning. i have looked for solutions online, found one guy that said for him it worked to make the screw of the adapter bigger with some rubber because in his case the screw was not lined up with the aperture hook of the lens (thats not the same in my case). tired this as well, funnily one time i somehow manage to get the lens on the adapter with the aperture working but after that always the same (it pops out a bit so i cant mount the lens on the adapter). I made a video, hope you can see the problem there

please help!

Novoflex NEX-Retro Reversing Adapter Sat, 28 Oct 2017 11:06:48 -0600 Vitaliy_Kiselev 18078@/talks/discussions

For owners of Canon EOS wide-angle or zoom lenses as well as Sony E-Mount lenses the NOVOFLEX RETRO-Adapters open up the world of extreme close-up photography with outstanding quality.


"The new NEX-RETRO reversing adapter from NOVOFLEX is a powerful addition to any Sony user's toolkit. It allows any Sony E mount lens to be attached to the camera in a reverse orientation changing the focal length to macro functionality with full electronic transmission as though the lens were mounted directly to the camera in its usual manner. We're delighted to bring this functionality to Sony users just as the EOS-RETRO provides to Canon users."

The NOVOFLEX RETRO-Adapters lets you mount the lens in reverse position on the camera. The ring transfers all control functions.

Example: With a Canon EOS 28-105 mm zoom lens in reverse position, you get an image ratio of 1:7 with a focal length of 105 mm from 1:7 to 2.8:1 at 28 mm.

This is a wider setting range than is possible with a macro lens.

The NOVOFLEX RETRO-Adapters are supplied standard with a 58 mm filter diameter. Stepping rings are available for other filter sizes.

  • Bring to life the finest details: NEX-RETRO allows reverse mounting of Sony E-mount lenses for close focus macro applications.
  • No compromise in flexibility: NEX-RETRO retains complete electronic functionality between Sony E-mount lenses and bodies.
  • Precision engineering: NEX-RETRO is the perfect tool to make the perfect picture even better.

Caldwell Photographic Inc. and Metabones is pleased to announce the Speed Booster Q666, a.k.a. “The Devil’s Speed Booster”, exclusively for Pentax Q series cameras. With its 0.5x magnification and world-record f/0.666 maximum speed, it is crazy wicked fast. So make a deal with the devil today and turn your Pentax Q with its back-illuminated sensor into a monster low-light machine unlike anything ever seen in photography. Attach a f/1.2 lens and stop down a little to see how Stanley Kubrick made do with f/0.7 for filming those famous candle-lit scenes in “Barry Lyndon”. Or open up all the way to f/0.666 and probe the darkness in a way that no photographer has ever been able to do until now.

With an advanced 6-element optical design, the Q666 packs lots of optical horsepower in a small package. Sharpness is excellent even at f/0.666 and is downright superb if you stop down to f/1.0. Distortion is very low, with a maximum value of, naturally, 0.666%. And thanks to the back-illuminated sensor used in Pentax Q cameras, the full f/0.666 maximum aperture can be utilized with minimal pixel vignetting effects commonly seen in other cameras used with high-speed lenses.

At f/0.666 (i.e., with a f/1.2 master lens) the MTF is high near the axis and only falls off gradually toward the corners. As the aperture is reduced to f/1.0 and then f/2.0 the MTF becomes very high and more even across the field. There is less than 1 stop of corner illumination falloff even at f/0.666. And guess what - there is no vignetting at all after the output aperture reaches f/1.82. Rectilinear distortion added by the Speed Booster Q666 is negligible at less than 0.666%.

Like all Metabones Speed Boosters, the Speed Booster Q666 is optimized to fully account for the camera’s filter stack located near the sensor surface. This is especially critical at the record-setting f/0.666 aperture now possible with the Q666. As a result, an enormous range of optics, from vintage film lenses to the latest digital designs, will function flawlessly when adapted to any Pentax Q camera. Planned lens mounts for the Speed Booster Q666 include a Pentax-K version and a Nikon F/G version with the most advanced Nikon G aperture adjustment mechanism in the industry.
