Pros: Sharpness, all metal (except the dials which are plastic)

Cons: I can't find any... Given the year in which it was released

Opinion: I find myself with one as the owner of a Pentax Mx that is no longer working. Unfortunately my lens is mechanically faulty, the aperture closes from 1.7 to 5.6 then freezes. The MAF ring nut is fine. however, as far as it reaches as an aperture it leaves me stunned by the sharpness. I mount it on a Lumix G100 with adapter ring. I conclude by saying that it is a pleasure to still be able to use it. I also have a 28mm f2.8 and that's also a Mr. lens.

Pros: Lightweight and compact, all metal, low price compared to the great quality it offers

Cons: It's just a little laborious to use, it's all manual. But you know when you buy it

Opinion: Bought a month ago for a few euros a perfect copy arrived The rings are excellent, minimum distance of MaF of 45 cm, depth of field scale for hyperfocal (can be useful) for those interested go to Pentaxforum and will find only excellent reviews It is not a lens framed and shot, it must be used calmly and you have to take into account some photos to throw away, But for a few euros you can take home an excellent product from almost 50 years ago. Recommended for those who want to get nice blurry and have patience

Pros: Light, good slow coating, compact.

Cons: At full opening it has problems with sharpness, contrast and CA. I would have expected better even to more closed diaphragms... but I have to note that my pentacon 50 f1.8 in m42 is considerably higher across the board. The Olympus 50 f1.8 car (zuiko) even better than both.

Opinion: In my humble opinion, having a copy practically as new in all, the fame of this lens is much more legendary than real. Those who praise so much of the merits have not tried the peers Olympus, pentacon, konica exanon, and Minolta rokkor. The same applies to the Pentax m 50 f1.4, inexorably detached from the Canon fd 50 1.4 and even the revuenon 50 1.4, not to mention the olympis and Minolta...

Pros: Sharpness, bokeh, colors

Cons: If we have to find one by force I would say surrender; A little too contraed. Assuming it can be considered a defect...

Opinion: A razor. Small, light, robust, functional and very sharp. It has an elegant bokeh and that vintage rendition, for the aficionados of the genre is a godsend, which combined with a crazy sharpness makes it a fabulous product. Remember that it is a vintage lens and then you work in total manual, which requires a minimum of expertise on various settings... Isn't this also the beauty of photography? :D I personally recommend it to anyone. Minimum cost maximum yield!

Pros: sharpness, colors, construction, compactness

Cons: if it were not for the fact that the internal "fin" of protection of the diaphragm transmission, create problems for my Eos 5D, I would say absolutely NOTHING

Opinion: It is a point that I have known practically since it entered the market. I tried it, almost by chance, on the Pentax MEsuper of my cousin, in the 80s and, although not an expert, I immediately noticed the incredible quality of this perspective: that sharpness and colors! every time I find it at the markets I buy it; pity not being able to use it, directly, on my old 5D. Since, however, I have several, one, (the aesthetically more battered) I sacrificed and I cut that inner flange (fin-shaped) that prevents grafting on Canon. What to say; excellent!

Pros: bright - clear - beautiful colors and warm - all

Cons: i dunno

Opinion: Beautiful, sharp wide open, very clear just closes. Warm, inviting colors. I noticed that in certain occasion change the color temperature according to the 'opening becoming more' cold closing. Quality / price ratio monstrous, to buy immediatamente!...............................................................................................................................................................................................................................................

Pros: Construction, sharpness, beautiful colors

Cons: For those who are used to always use only the autofocus might be a bit difficult at the beginning

Opinion: Objective purchased on the internet as new. Build quality excellent, nothing to do with the 50 1.8 canon, this is born in a period when the concept of "disposable" was not yet known. Sharpness crazy already at f / 1.7, brilliant colors and bokeh that I really like. It 'a long time I wanted to take a fifty, but the 1.8 canon, I was never convinced enough, I saw it in the store several times, all that plastic left me very puzzled, after taaante nights spent reading reviews on this site I decided to take the 40 2.8, great lens but f2.8 brightness and so I had little desire of 50ino is back stronger than prima.rnDopo reading around that Sigma and Tamron (also 50mm) seem to have problems f / b focus and to find a good copy it takes quite a bit of luck, I decided to take this jewel, manual, so you avoid these problemi.rnE 'came about by chance while looking for Zenit and seeing the pictures you can make me hit and I got subito.rnDalle first pRove has not lived up to expectations, worth every penny of the money spent, it's spectacular. Perhaps you could put some troubled people who are not very used to the manual focus (and not only in this case the diaphragm) but with a little practice you should be fine, then if you want to simplify your use during practice you can always mount the adapter ring with chip Focus confirmation fuoco.rnUnica downside: addictive, we need to remove it and leave it difficult to casa.rn

Pros: Metal construction, sharpness crazy, saturated colors in all openings

Cons: .....

Opinion: switch to digital has certainly its advantages and with the new Pentax camera bodies mistakes is quite difficult because all the automatic available. The situation is different when you combine old and new technologies, such as the use of this lens with a body KX K7.rnSi lose some or all the automatic and in some cases as a correct little shooting with shutter speed and aperture, before getting desired result, much more than with the objectives automatic ... but if the results are what you will get with this in mind it is certainly worth doing some shooting empty. Sharpness, colors, blurs and contrasts are beautiful. For a view that the market is worth little or nothing is a real slap in the face to the more modern products, refined and noble. This is the kit lens fixed on my K7 and if the need to use will allow me not take it off even if I have to give up the automatismi.rnInsieme 135 f2.5 Super Takumar are part of my outfit ... I think that having more optical modern, do not ever take away from borsa.rnFAVOLOSO

Pros: Economic, crazy sharpness, light and small. Metal body.

Cons: If being vintage and completely in manual is a sin ......

Opinion: Crisp colors. If not used in TA returns saturated colors and sharp images. Used for portraits is phenomenal. Very nice bokeh effect. With little more than € 50 you take home a piece of the history of photography and a nice glass. The metal construction gives a solid feel that only certain objectives forward. A word of advice before buying is to check the presence of dust and mold. We always talk about cars which have more than 30 years some signs them can (and should) have. To give a sense of professionalism to seek the advice hood (maybe metal). The original rubber and aesthetically I think it is not the best.

Pros: Sharpness, price, compactness

Cons: No

Opinion: I use this lens reversed on extension tubes for macro high magnification (3x). rnIl manual iris has the advantage of allowing adjustment also reversed (which is not possible with the new lenses without aperture ring). Sharpness and color are good, even at 3x, where it is safely usable also in diaphragms chiusti (f8-11). rnrnIl price is great in relation to the quality you can find (only used because it is out of production for years) to 30-40 €. rnrnL'unico against that is to mount it normally, with adapter, on a full frame DSLR, should be removed the protruding pin inside and the protective part of the same, that the film cameras were used to close the aperture when shooting. If the rear screws are not damaged (unfortunately two out of five of those in my lens you can not unscrew), this is not a problem: just unscrew and remove the two pezzi.rnrnIn conclusion: a perfect lens for high magnification macro, lightweight, inexpensive and crystal clear. Viable alternativeMP-65 and for those who can not spend so much.
