In addition to filter diameter, you need to specify the thread pitch, the linear (axial) distance the filter, screw, etc. travels for one (or more) full rotations of the thread. For SAE (or SAE-derived) threads, the pitch is usually specified in number of threads per inch. For example, the 1/4"–20 tripod mount and screw have a 20 thread-per-inch (TPI) ...

No. There are several problems here. This lens looks a lot like the Senko 50mm f/0.95, i.e., it is a C-mount lens for 1" format video. This lens vignettes even on micro four-thirds (2x crop). There's no way the image circle will cover an APS-C or full-frame camera, and the registration distance is much much smaller than that of Nikon F. In order to get the ...

Those lenses sound like auxiliary "converter" lenses, which are generally intended to thread onto the filter threads of another lens to convert that lens to a longer or wider focal length. They're more common for advanced point-and-shoot cameras than SLRs and won't do anything useful without a lens to mount them onto. In my experience, these converter ...

Micro SD to SD adaptors are just passive wiring adaptors. So they should not have any impact on speed.

Adaptors to reduce the filter thread of a lens are a bad idea. They cause vignetting (dark areas in the corners). You might get away with a reduction of 2mm as different brands standardise on different sizes. Some kit lenses have bigger threads than they need so that the manufacturer needs to support fewer standard sizes. Apart from these 2 cases your not ...

The primary advantage of the former is that it avoids necessitating the purchase of a CF-USB adapter to upload photos to my computer (and from thence to my hardrive). If this is your main reason then it is not worth it. I have a 40D, and bought an adaptor and a 16GB SD card. So far it all works fine, however removing the SD card from the adaptor is ...

The Chinon CM-5 uses a Pentax K mount and there are adapters available for about $15 to mount these lenses on your Canon 1100D. Mike Butkus Camera Manual Library Fotodiox Adapter

No. The L830 does not have a filter thread, and no accessory tube with which to attach a filter to the front of the lens. Any fixed-lens P&S cannot swap lenses, but can only really take a filter in front of the lens. You can add filters that can add macro close-up capability, or act as teleconverters to increase or decrease the focal length of the lens, ...

Firstly check that in the AMD panel you can configure which graphic card is used when Lightroom is started. Perhaps disable one of the graphic cards before starting Lightroom. Moreover, a good solution is to completely uninstall the drivers, clean them, then reboot and install the drivers again. This is just to be sure you have a "clean install" of the ...

Consider Sony A-mount Your Tamron lens is Minolta AF mount. This is, in fact, the same lens mount that Sony's A-mount SLT cameras use, so if it's absolutely imperative that you use this lens, Sony's A-mount cameras would not require an adapter and would give the highest level of compatibility (including autofocus). However, to most of us, a third-party slow ...

The ratio f/2.8 means the diameter of the entrance pupil is equal to the focal length divided by 2.8. The key thing to note about the above is that the entrance pupil is the image of the aperture stop as seen through the front of the lens, the ratio does not depend on the physical size of the aperture itself. A rear-mounted 2x teleconverter, such as you ...

No, because the register (distance from the mounting flange of the lens to the sensor plane) is quite short.

It is a "non-CPU lens". The camera must be in camera Manual mode M. Exposure settings are manual. The scope is of course manual focus. See D5300 REFERENCE manual, page 228. The REFERENCE manual is available at http://downloadcenter.nikonimglib.com/en/products/25/D5300.html

Most Soligor mirror lenses have a T2 mount. To use one with your Canon EOS 5D (or any other Canon EOS camera) you need a T2 to EF adapter. Realize that you will need to manually focus and shoot in manual exposure mode with such a lens. Also note that there are three tiny set screws that must be tightened after you attach your lens to the adapter to prevent ...

No, there is no such adapter. The Rokinon lens a manual-focus, manual-aperture lens. It does not have a built-in focus motor, nor can it interface with a focus motor in a camera body that might have one (the Sony a7 does not).

If you want to continue using your seven Pentax lenses, your best option would be to upgrade to a better Pentax camera. There are mechanical adapters that allow Pentax K-mount lenses to be the correct distance from the sensor so that infinity focus is possible with Canon EF mount cameras. But you're going to give up almost all automation: autofocus and any ...

For the most part, aside from the added instability and possible added variance in adapter thickness when stacking adapters, you're correct, but there are exceptions. Not all the Samyang lenses for mft are identical to their dSLR counterparts. Samyang does make two lenses that were specifically designed for mirrorless mounts and do not work on dSLRs, and ...

It sounds like they're actually adaptors/filters for lenses, rather than lenses in their own right. The 52mm thread can be screwed onto the front of a variety of lenses, like the standard 18-55mm kit lens. The 2x telephoto adaptor will make the lens "longer", or more telephoto (it will magnify objects more), while the 0.45x wide angle adaptor will make ...

Nikon DSLRs do not play well with M42 lenses, as flange focal distance (46.5 mm) of Nikon F-mount is longer than on the original M42 cameras (45.46 mm). The lens was designed to sit closer to imaging plane (film) than it can physically reach on your DSLR's body, and this robs the possibility of focusing anywhere near infinity; the lens can be focused only in ...


3

In manual mode I can not select the aperture but only shutter speed and exposure. That's correct. The M42 mount doesn't have any provisions for the lens to interact with the camera in either direction, so shutter speed and sensor sensitivity (ISO) are the only things on the body you'll be able to adjust. Aperture is, obviously, on the lens. The images ...

Pentax doesn't, because Pentax doesn't make any adaptors for other people's lenses. However, assuming this is an old Olympus OM lens, you can get a third-party adaptor — for example, this $40 one from FotodioX. Note that the flange focal distance of the K mount is 45.46mm, while that of the Olympus OM mount is 46mm. In order for an adapter to be a simple, ...

If the charger is not indicating a full charge by displaying a constant light but blinks at a higher frequency after about an hour then the battery appears to not yet be fully charged. If you are only going by the four or five segment battery symbol on your camera's LCD anything over about 75% will usually show fully charged, since the first bar doesn't ...

This thread on forum.mflenses.com concerns the same issue, and seems to answer the question. Poster SonicScot has the same problem and shows how it is caused by the focus ring extending further than the inner ring on the lens, which is supposed to touch the adapter. Clearly the focus ring is in the way of the adapter. I'd like to know if there's a way of ...

So the adapter is stuck on the lens, right? Understanding what's going on underneath might help. Here's a picture of a Nikon adapter and a Nikon lens. 3 things here: 1) The pin sticking up from the adapter. That goes in and out of the adapter 2) The button / knob on the adaptper. That moves towards the camera end of the adapter to make the pin (1) ...

I would venture to say that it's a Miranda Bayonet Mount. I use visual references and measurements to positively determine a mount. I would advise that you do the same before investing in another adapter. But your lens does have MIR imprinted which is a good clue. Confirm what you have with these resources: http://members.tripod.com/rick_oleson/index-99....

This is either a Vivitar T4 or TX series lens. T4 and TX lenses are interesting because they were designed to be mount-agnostic; that is, they have interchangeable mount adapters, so you could move your lens to bodies with different mounts, just by getting the appropriate Vivitar T4/TX adapter. As Gabe Krause's answer indicates, this particular lens has the ...

It's possible that a retailer would package "X-to-77mm" step-up ring sets, but I've never seen such a set. However, for most photographers, it's not a hassle to get a dedicated "X-to-77mm" (or replace 77mm with whatever your largest lens filter diameter is) step-up ring for each lens. Those rings are individually readily available from Amazon, B&H Photo ...

Although not the primary purpose for which it is designed, something like this Hot Shoe-to-PC adapter will probably do what you want. Get it in whichever version matches your camera's hot shoe pin pattern and you can also use it for the rare occasion when you want to use a TTL flash or a PC Terminal¹ connected flash without removing your adapter. ¹PC in the ...

This is likely a Minolta SR mount, also called Minolta MD sometimes. For comparison you can see the mount of my Minolta MD Rokkor 45/2.0 lens: The gap in the metal on the left and the pin on the right side are characteristic. The pin is ~4 mm higher than the surrounding metal ring of the mount. The outer diameter of the thin bright metal ring is 42mm (...

Is there any type of lenses that can be adapted to Nikon F mount(modern DSLR or old film) without any lens modifications, using just adapter and have fully functional lens with infinity focus. There are no other DSLR mounts whose lenses will retain infinity focus without modification when adapted to Nikon F. There are some universal mounts that can be used (...
