If you move the focus ring, you will find the the 3m/9ft mark is also in orange. Many Pentax wide angle lenses use an orange marking at f/8 which corresponds to an orange hyper-focal focus distance mark on the focus ring. The orange marks are just for convenience for a quick hyperfocal distance reference. When the orange marks are aligned, by using f/8 at ...

Just based on visual comparison, this lens appears to be a Helios 44M-4 58mm f/2-16. From the images you linked to, it appears that part of the lens is missing. In the 2nd image, around the lens barrel you can see what appears to be front element retaining clamps or springs. (Helios 44M-x Lenses, in order: 44M-4, 44M-5, 44M-6, 44M-7) How I found it: ...

This is the first, "zebra" version, optically the same design as Pancolar 2.0/50. The aperture control switch ("tumbler") should have 2 positions, "A" is counter-clockwise when looking at the front element, "M" is clockwise when looking at the front element - not 3 positions. The rear part of the lens should have an actuator pin that, when pressed, makes the ...

Many lenses from that era had the f/stop calculated by the lens designers to be the "sharpest" or "sweet spot" marked in a different color than the other f-numbers. A cursory survey of a couple of reviews of the lens in question indicate that the reviewers found f/8 to be the sharpest aperture setting. As this answer points out, this particular lens also ...

The lens comes from the good old days of film based street photography. At that time there was a philosophy of "f8 and be there" - you can read a bit more about it on https://www.adorama.com/alc/0013109/article/f8-And-Be-There. The autofocus had not yet been invented, and speed was important. A solution was mounting a moderately wide angle lens and pre-...

Provided you have more than average skills with fine mechanics, it can be done. The lens focusing mechanism has a couple of guide rails, which are probably loose and must be reattached in order to have it working normally again. When the second of them came loose, focusing became hard, as the focusing rail probably would twist and not be aligned when ...

The focal length stays at 50mm, but the field of view will be that which you would get from a 100mm lens on 35mm film. Depth of field characteristics at a given aperture will be that of a 50mm lens. There are special adapters, called focal reducers or speed boosters, that shorten the effective focal length (like the opposite of a teleconverter). Since these ...

I think the lens flare is a side-effect 2 things: simple Tessar lens design, and little or no coatings on the lens elements. There's probably nothing you can do to "accidentally fix" the flare on this lens. (edit: nothing normal, that is. I supposed if you were to have anti-reflective lens coatings applied to the lens elements internally, you'd reduce some/...

Ordinarily, it is impossible to use an unmodified M42 lens on a body with a Nikon F mount with an adapter that maintains infinity focus without the use of additional optics. Exceptions will be described later. The problem is similar to using FD lenses on EOS bodies with EF/EF-S mounts. The M42 mount has a flange-focal distance of 45.46mm, while Nikon F ...

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 ...

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 ...

There no significant disadvantage (but see the link in the comment above). However when you say 28mm is an important focal length for you, I'm not sure if you are aware that on a an EOS T3 you have a crop frame sensor. The effect of this is that focal lengths quoted on lenses should be multiplied by about 1.6x to work out the equivalent focal length on a ...

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 ...

This isn't a definative answer, but a speculation and something for you to check that's too long for a comment. I'd be surprised if the lever had a visible effect. Try turning the focus and f-stop rings at the different positions and see if there is a difference in feel or motion range. I have a pre-war Carl Zeiss Jena 50mm lens that has a separate ring ...

I propose to add to the list of Helios 77m-4 50 mm f/ 1.8 МС. It differs little from the 44-series (including the price). I have this lens (+ Sony Nex), I am very pleased with its bokeh. Examples of photos (not mine) can be found here: http://lens-club.ru/gallery/lens/c_490.html IMHO it is the best choice. Returning to the 44-series. It should be divided ...

It's a good practice to use non-native lenses on MFT cameras due to short flange focal distance of MFT system. But to my mind not all lenses deserve to be used. Some will give a pale ugly picture, but others, on the contrary, will create a miracle. Wide angle. As said by @Jeremy S. you'll get more telephoto lenses so 24 mm FF (full frame) lense will be ...


2

The lenses you have should adapt and work fine. They will be longer lenses (more telephoto) then what you're used to. But your kit lens can probably cover wide angles if you need them. They won't be quite as long seeming in APSc, though they will still be quite a bit longer than full frame (traditional 35mm) - about 1.5x. With m43 your lenses will be ...

When it comes to adapting lenses with simple ring adapters so that they'll still focus to infinity, the issue is merely one of image-plane to lens mount depth. Because a ring takes up physical space, you can really only adapt from a thicker mount to a thinner one without requiring a glass element to act as a teleconverter (and possibly diminishing image ...

If it's the usual teleconverter (usually 1.4x or 2x) it won't change anything. You can't focus to infinity is because your registration distance is longer that the focus distance. The teleconverter changes the focal length of your lens but not its focus distance. There are devices that look a bit like teleconverters (they go between the lens and the camera) ...

4K will always miss out compared to a RAW still as there is so much more data that you can recover from RAW. With 4K the camera has already done the majority of processing in camera. However, I have used 4K to capture individual motion frames in relatively low light with reasonable results ... but it depends on what YOU define as reasonable! This 4K image ...

A L class Praktica, say MTL5, should meet all the reqirements. They are built like tanks, have reliable metal shutters and TTL metering. The meter tolerates different battery voltages and shutter is fully mechanical. The higher models have split screen focusing, L and L2 only microprism (so avoid these). They should not be hard to obtain in Poland (there ...

Are there any significant drawbacks I should take into account before doing this? You must use stop-down metering. You must focus using a lens ring. You must set aperture using a lens ring. You will have no EXIF information from the lens. The camera cannot control the aperture setting of the lens (i.e., you can only shoot in Av or M modes). M42 glass tends ...

It is 44 and 44-2 that are legendary. I have Helios 44-2 (I'm sequoiagrove) and it is very nice. However, I must say that as a Nikon user you have the wrong camera for vintage lenses. You can only use them for macro, otherwise, to focus infinity you need a bad adapter with a cheap not-fit-for-photography lens in it.
