SMC Pentax-M 200mm f:4

Let's take inventory of my small equipment to me that I ... After 135mm , I wanted a slightly longer focal length - the 135mm, it will not fetch you a little bird on a high Brache, except to climb yourself the tree.

So I went back over the bay with my little basket, after 50mm f: 1.4 British and 135mm f: 3.5 Swiss Hellenic is a 200mm (always in the range of Pentax SMC-M) I've dug up for a very reasonable sum.

• Type: Fixed focal lens manual
• Manufacturer: Pentax
• Model: SMC Pentax-M 200mm f: 4
• Purchase Date: November 4, 2007 ( on ebay, from Greece)
• Filter Holder: 52mm
• Sunshade integrated
• Aperture: f / 4 to 32, eight blades
• Focus: 2m to infinity

This has the advantage of being very compact in terms of its focal length. A little heavy, perhaps: it does not plastoc subsequent series F, a little more cumbersome as still as the 135mm, they can really take with you without even thinking. Question

image quality, no bad surprise from the first test I scored quite satisfactory. The grip is pleasant, well balanced the resulting image has a good definition, even a large opening - well, its openness: it's f: 4 'only' . Knowing that the camera in hand, it is difficult to go below 1 / 250 th second, it is understandable that it is not so common to go beyond f: 8, especially winter. The image quality at full aperture is welcome!

I use a lot more this goal in recent months, for two reasons: the purchase of a 300mm (which I will) helped me appreciate how much this was actually 200mm so little and light, and then one of the benefits of fatherhood, is that you can use the stroller to lug around the tote photo, it was quite full!

SMC Takumar 1:3.5 / 35

To complete the kit accompanying the paternal SP500 after 55mm and 135mm , the youngest: a wide angle, 35mm. 35mm, it is not very wide angle, but it is a focal length that I like because, unlike 28mm, deformations straight lines (barrel effect) are not too pronounced. Practice, especially for photos of the building.

• Type: Fixed focal lens manual
• Manufacturer: Asahi Pentax
• Model: Super-Takumar 1:3.5 / 35
• Focal Length: 35mm filter holder
• ;:
• 49mm Aperture: f/3.5 to 16

A small feature of this range of objectives: the objective of medium length is physically longer than the general angle. Pictured from left, they are focal increased: 35, 55 and 135mm, left to right. This is not the case with ranges latest: hunting millimeter and progress of optical helped shorten the 50mm, while the large angles are nearly incompressible: the distance to the film being in any way higher than their focal length, they contain necessarily divergent lenses to compensate for this difference. That is why the goals most compact frame Pentax are now 40mm: the shorter focal length for which we can do without negative element in front of goal.

This is not troublesome for the money by cons for SLR APS-C is a bit annoying, since the objective corresponding to a 50mm would be 28mm, which one would like that it is the smallest (and most open) possible ... No simple remedy to this concern, but much closer to the front of the sensor housing, thus eliminating the compatibility of these cases with optic old - a strong point of Pentax in the heart of its marketing communications ...

SMC Takumar 1:3.5 / 135

The following objectives SP500 : after 55mm the 135mm. A short telephoto lens handy, cf. what I said about SMC Pentax-M 135mm f: 3.5 .

• Type: manual lens fixed focus
• Manufacturer: Asahi Pentax
• Model: Super-Takumar 1:3.5 / 135
• Focal Length: 135mm
• Holder Filter: 49mm
• Aperture: f/3.5 to 22

Comparison with SMC Pentax-M 135mm f: 3.5 shows the evolution of optical Pentax during the 1970s: they both have a filter holder 49mm (while the immediate successor of the SMC-Takumar, SMC Pentax (not M) bayonet was in 52mm), but the Takumar is more end, the tube being adapted to mount M42, narrower, and it is against the longer, have not benefited from advances in optics of the Pentax-M.

In terms of image quality, I have not noticed any obvious difference, in terms of convenience, note that the Pentax-M 135mm features a retractable sunshade, in-lens ;: the advantage of having a little more leeway in terms of size, I suppose. The Takumar was sold with a metal hood, but I noticed it caused a significant vignetting of the images: it is too long, while the literature gives the Pentax as suitable for this purpose ... 'll Understand.

Note on the right picture, some features of the draft final optical Asahi Pentax screw: the small pin that protrudes into the frame. When the lens is mounted, the housing press stud is now open aperture, it's only permanently active when the cell to measure light that the diaphragm is released. On the side near the frame, button, zipper Auto / Man : it only serves to disengage the previous mechanism, where we mount the lens on a box of another brand which the spike clutch would end down permanently. Obviously, given in 2008, the reference Auto let wait much more ... The charm of old equipment!

Super-Takumar 1:2 / 55

After the presentation of SP500 , its goals - the good old Takumar mount M42 ...

As was the practice before it starts to sell the zoom with a vengeance, the kit that we had suggested to my dear father consisted of housing, some eccessoires and three goals : a target of average focal length (55mm) wide angle (35mm) and telephoto (135mm).

• Type: manual lens fixed focus
• Manufacturer: Asahi Pentax
• Model: Super-Takumar 1:2 / 55
• Focal Length: 55mm
• filter holder: 49mm
• Diaphragm: f / 2 to 16, six blades

is the basic objective of all, curiously, while the other two are in the range SMC Takumar ( super multi coated ), this n is that the range Super-Takumar, including multi-layer coating is deemed to be a little worse ... But this is by far the one I used most often, and it has never particularly been a problem. In a pinch, by comparing all things being equal with the target MSC, there is slight color shifts ... And yet, it is not clear.

course, it would certainly be better with the SMC Takumar 1:1.4 / 55, which was absolutely unaffordable at the time but found for cheap now ... But it takes very good pictures with it.

Asahi Pentax SP500

a break in the descriptions of my equipment to mention a few devices that I used or that I use although they are not mine, and in particular apparatus and step-father's paternal. Starting with a device which, if not the buyer, I was one of the first topics: Asahi Pentax for my dad.

• Type: SLR
• 35mm Manufacturer: Asahi Pentax
• Model: Spotmatic SP500
• Year of manufacture: 1980-1986
• Purchase date: early 1972 (not by me, I was a year!)
• Mounting: screw type M42
• Shutter: double curtain side-scrolling, 1 s to 1 / 500 th (actually the speed at 1 / 1000 th works although it is not marked on button speeds), Bulb

see this unit talk about the entries in photos and days ; the latest was illustrated by the same photo as this one.

In any case, a device particularly robust, as his successor the Pentax K1000 that I bought a copy a few days ago. The K1000 is identical to the Spotmatic (rather than the SP1000 SP500, but they are virtually identical) to the flash shoe near (the Spotmatic do not) - only changes the lens mount. The mount of M42 Spotmatic is much smaller than the K bayonet who succeeded him, so they appear larger than the K1000: more space free on the front ... But I have a case is designated for the Spotmatic (as marked Honeywell Pentax, the brand under which Asahi Optical Co. for providing its Spotmatic the Americas): it is exactly the right size for the K1000.

Asahi Pentax was the last major manufacturers to have kept the screw mount, until the early 1970s. They were not bad, these horses, but we must recognize that change is on target when mop requires a certain dexterity. Moreover, if a tip at the frame allowed the development diaphragm open, it had to close it when measurement of light, while with K-mount, everything is done and it is open aperture at the time of shooting it is adjusted. This allows you to work simultaneously on the development and measurement of light, then it is difficult to adjust the focus iris closed, especially if you are at f: 16 or beyond ... On the other hand, no need for button control depth of field (which is a clutch mechanism under open aperture), because the passage in the measurement mode automatically.

I took my first pictures with this camera in the 80s when I was 11 or 12 years (the advantage a rugged) I made a half-dozen rolls during my years of college and high school from 1982 to 1987 (with some moderation, therefore, the development costs being fabulous in terms of my money pocket) I borrowed again during my trip to South Africa in 1997. But it is always a pleasure to handle, although I now use my own equipment to take pictures. To recover the memory of those early gestures clicks.

YashicaMat 124G

dint make mumuse with dandruff, you want to have anything other than the traditional perforated films 35mm (format 135), for example (chronological classic) format 120 : rolls 6cm wide. For that, it is still necessary to have a camera that uses this format, knowing that the legendary Hasselblad are certainly excellent, but expensive, even very old and used, and most of Kodak Brownies found in the flea markets are totally unusable.

A good compromise: the camera reflex twin goals. The most famous in this genre is the Rolleiflex, but again, it costs a crazy price, even used. A little less insane than Blad, but crazy nonetheless, when we have casual use. So, it's on a device relatively new, and manufacturing in Japan, the YashicaMat 124G.

• Type: SLR 6 × 6 to twin objectives
• Manufacturer: Yashica
• Model: YashicaMat 124G
• Year of manufacture: 1971 - ?
• Purchase Date: October 21, 2007

The principle of these devices: the two objectives have a formula Optical identical and are set to the same front moves and which moves forward or backward to complete the development. The top one allows targeting, through a mirror and a frosted one looks at the top (see third photo). The lower one is facing the film, it was through him that is shooting. It has the advantage of focusing directly, constantly on the frosted the sharpness of the image, without the need for a telemetry system, without the disadvantage of a movable mirror, mechanically sensitive ( especially as the mirror is larger than 35mm).

The goal is not interchangeable shutter it is integrated, it is a radial valve located at the focal point of the lens, not a horizontal or vertical curtain located at the focal plane, ie just before the film. Advantage: the focal point, as its name suggests, the light corresponding to the image is almost together at one point, the opening and closing the shutter is simultaneous for all the image.

On a 35mm case, however, the opening of the image is shifted in time by following the path of the curtain - even if the entire image receives the same amount of light because the second curtain (which ", closes the window") moves in the same direction as the first. The exhibition is just shifted in time from one end to another image, a few fractions of seconds. It's trivial for pictures in natural light, by cons for the flash picture is more annoying: the flash is anyway much shorter than the opening time of shutter must ensure that the first curtain is finished and open the second has not begun to close when it starts Lightning - otherwise a part of the photo is taken with flash and one without. At high speeds, close the second curtain starts before the first has finished open: no flash picture possible. We must therefore follow an exposure time limit for the camera flash, this is called speed flash sync (between 1 / 60 and 1/125th following boxes).

On radial valve housings, therefore, no problem: you can take pictures with flash at any speed, which is interesting when using the flash as a supplement and not as the sole source of light.

addition to these theoretical advantages, the device is YashicaMat most sympathetic side of the crank film advance (see photo 2) is a bit noisy and not very convenient, but deliciously retro. It has a photocell (the small circle above objectives, the first picture), but on mine like many of her contemporaries, she no longer works. The lens is also of excellent quality, enjoying the same treatment as that of multilayer casings 35mm from the same period. I owe him the coup some pictures which I am relying more r: is not it ultimately the best argument that can be given for a camera?

SMC Pentax-A 28mm f:2.8

Although I tend more toward the telephoto Avoi some great angles do peuit not hurt. I came across this little 28mm by chance on the bay. Not too expensive, and more SMC Pentax-A, non-M, which does not spoil anything.

• Type: fixed lens, manual focus and iris automated
• Manufacturer: Pentax
• Model: SMC Pentax-A 28mm f: 2.8
• Purchase Date: September 27, 2007
• filter holder: 49mm
• Aperture: f/2.8 to 22, five blades
• Focus: 30cm to infinity

So why A ? That's automatic simply: the diaphragm of the lens can be set directly by the housing, without user intervention. If the box has a program mode, it will even automatically adjust the aperture and shutter speed, depending on available light and sound or its programs.

Specifically, what's the difference? Unlike the F-Pentax lenses, there is no integrated electronics, and mechanical couplings are very close to those goals Pentax-M. But not quite ...

First, there are a number of electrical contacts that allow the case to know the characteristics of the target. Objective side, in fact, there is not actually contact the contrary, a small plastic pellet is at the location of some of the switches used for housing insulation, for others, contact is established by the metal frame. These contacts or absence of contact can encode openings maximum and minimum diaphragm history that the case does not ask the impossible.

An additional contact is a bit unusual, distinguished on the fourth picture, roughly halfway between the two screws on the frame. It corresponds to the A position marked on the aperture ring (see third picture) and when this position is chosen, this little metal point juts slightly, making contact which means the case that one wishes to use the auto iris. Note that if the case does not use these contacts, the target behaves almost as an objective of the series Mr.

A more subtle differences: all mount lenses K have two mechanical couplers. One relays in case the position of the aperture ring and the second blocks the diaphragm in the open position to develop and adjust speed and aperture while keeping the lens wide open, which is much more convenient . Simply, the case made its claculs taking into account the width of the diaphragm when it is closed, information provided by the first coupler; when it starts shooting, the second coupler recedes, leaving the diaphragm closed.

On the objectives of series A, the second coupler is slightly modified its mode of action is more precise and carefully calibrated (the small bitonnieau metal visible on the top of the frame on the fourth photo). Result: while for the goals of K-series or M, his action was an all or nothing (keep the iris open, or back completely so that it closes at the selected position on the ring), with the objectives A, the case can not roll back the coupler only partially, leaving the diaphragm close, but only chosen by opening the housing. This is how the opening is chosen.

course, on my boxes ME Super or MX, it makes me look good: these packages do not have the ability to control the diaphragm and a M series lens would have given exactly the same result . For cons, the P30T (which I am separated from) the MZ-10 MZ- and 5n have this capability, and the Pentax digital SLR cameras as well, which is seriously taken up the series lenses A!
