leica_elmarit28_f2-8rLeica Elmarit-R 28mm f/2.8

Pros: Aesthetically pleasing lens with its conical-shaped hood, Leica mechanic, excellent optical quality but all to be studied, particularly pictorial and creative effects

Cons: Vignette visible to open diaphragms, focal aberration "spherical"

Opinion: It is a definitely dated lens (mine is from the early seventies of last century) but it can give you great satisfaction. I've been able to mount it on Nikon with the adapter ring that allows for endless focus (I tried both the Fotodiox and the Leitax, both valid but with a run end that goes beyond infinity, but that's not a problem Essential) and of course you have to focus manually. The yield is exceptional for the quality of the colors the environmental sensation it makes. The open diaphragms are noticeable for vignetting (post-production eliminable) that is not only visible from f8 onwards. Another problem is the focal aberration that the low diaphragms blur the parts not in the center of the image as if the lens was to focus not a plan but a curved bottom. It is not particularly noticeable, but it is a defect that the full frame is noticeable, however, that it can be used in its favor if, at the sides of the frame,39 there are some of the closest parts that remain astonishingly in focus (see the photograph of the gate below). It is therefore a lens with merits and defects, which can be greatly appreciated if you learn to know it. I'm glad I bought it (350 euros plus 50 or 100 euros the adapter ring).

leica_elmarit_r60macroLeica Elmarit-R 60 macro f/2.8

Pros: Color, alienation effects, setting, three-dimensionality and unfocused excellent, refined mechanics, the used price much content

Cons: Some difficulties to adapt the lens on Nikon, apparent lower image definition than equivalent current goals

Opinion: There are books on Leica optics with expert appraisers, photographers and collectors. In my case I coming from photographic experience with the Leica M film I really liked the ability to mount these old lenses on new digital machines. rnHo the Elmarit 60 mounted on a Nikon adapting a Fotodiox ring, by following the instructions found online (Adriano Lolli on YouTube). The result was satisfactory: of course you lose the focus and exposure automatically, but you can shoot in manual focus to infinity. rnGli shots have returned me the color, the atmosphere, typical of Leica I knew. By comparing these images with those obtained with Nikon lenses I found most harmonious tonal values, more settled, more three-dimensional, even though at first glance may seem more "mellow", not dolphins in certain micro-details. I'm not an expert in the field of lenses, but for my feelings I found very pleasant lto yield and the creative possibilities of this lens in the landscape shots and macro photography.

sony_a7Sony A7

Pros: Great FF sensor, size and weight, and robust metal, adjustable and readable display, ability to mount old objectives is FF which is cheaper but high quality

Cons: electronic viewfinder that compared to the SLR disappoint, angular shapes of the machine, they are likely luminous reflections in strong backlight

Opinion: one can only be pleased with this machine. Finally it allows using finite goals for years in the closet, which often have great photographic potential, but They come because we left them in the digital age. In my case I started to shoot with Leica lenses with satisfaction of finding the colors and "textures" dell'immagini I remembered, for me very beautiful and special. Of course there are the dedicated targets (few for now). The Sonnar 35mm makes the machine could say infallible, like rendering of detail and clarity, ease and immediacy in focus, size and total weight, the more the lens machine, "pocket" in the sense that you can put it in the pocket of sweatshirt or even in some pockets of winter trousers and wanting, almost always have it with you. There are cons though. If we make the comparison with a reflex we forget to find the image that we used to see in the viewfinder. It is hard to reconsider what you seeviewfinder with what is before us, we need a bit 'of time and you should also get used to. Sometimes it happened to me that the proximity sensor that turns off the display to activate the viewfinder when you approach the eye to the machine, turn off both for a while ', the viewfinder and display. You have to wait or take the dark. He was also surprised by the glow that is found in few clicks strong backlighting, with the sun or a lamp in certain angles. It seems to have a problem of reflection off the image sensor. I concluded that it is a machine to be recommended to those who want to take great photos, comparable to the return of any SLR FF, who likes to reuse the old targets and to those who want to shoot without carrying around a "box" from 1.5-2 kg and those who like to photograph calmly, because the shot is not as immediate as with an SLR

sony_fe35_f2-8zaSony FE 35mm f/2.8 ZA Sonnar T*

Pros: Sharpness, color and imaging performance typical Zeiss, relatively low cost

Cons: Lack of reading focal distance

Opinion: Not much I use this lens but now is going steady with my Sony A7. I can put them in the pocket of his sweatshirt and go wide so equipped camera without difficulty and dimensions. The yield is good, comparable to the optical Leica where I come from. Even at full aperture the photo quality is good and you can get an effect of focus behind on the first floor. My experience, not by professional photographer, I do remember, however, the results of photos taken with the Rollej, very sharp and contrasted.

nikon_28-85Nikon AF 28-85mm f/3.5-4.5

Pros: Excellent sharpness and mechanical construction

Cons: Weight and size, focus and manual adjustments

Opinion: I bought this 90 years old aim to use it on FF Sony A7, almost out of curiosity. I had read some reviews on the internet, including http://kenrockwell.com/nikon/2885af.htm who spoke very good vintage of this goal. After you've tried on several occasions on the Sony FF and also on a Nikon APS-C I had confirmation of optical and mechanical quality of the lens. I bought in a shop in Milan, advertised here on Juza, and I can say that is true of most of the 170 euro paid, shipping included. Photos taken are very sharp and are comparable with those taken with fixed focal. It also has the ability to take pictures in the macro focal 28 mmm, where, however, it takes some skill to achieve them. Of course you need to manually focus, as it was once on the old film camera, and Sony with the adapter ring you must also manually diaphragm. All operations you back in time, but I would say quite simple and straightforward to do. The results are there andgive satisfaction. Percontro is a perspective all metal that has consequently a certain weight and size with the addition of the adapter ring is quite relevant

konica_hexanon40Konica Hexanon AR 40 mm f/1.8

Pros: Sharpness, already at full aperture, brightness and below cost

Cons: Particular tone color (slightly warm color in my perception) that can be easily corrected in post-production, if disturbed.

Opinion: I know by the time the objectives of the Konica Hexanon and their excellent quality on the machines reflex eighties. With the appropriate adapters now you can use them with satisfaction on digital ML and with good results. I recently purchased the 40-1.8 and mounted on Sony a7: was very convincing in the surrender of the shots. The sharpness of the images, already at full aperture, its extremely small size and low cost makes this lens really advisable. rn

sony_nex_6Sony NEX-6

Pros: Very compact with a DSLR sensor, possibility to mount leica objectives and other manufacturers with the adapter rings, swivel display, intuitive menu and easy, excellent and reliable quality of all

Cons: It makes no sense the wi-fi that is attached to, without having to provide a touch screen display

Opinion: 2C for the color and sharpness. The ultimate would be to employ them on a FF, but percontro you lose the compactness and portability. rnHo found absurd claim to be able to use the wi-fi without a touch screen. To achieve something you must climb up the mirrors, taking too long with laughable results. This aspect of the secondary, and I still think I concluded that the nex-6 is of excellent build quality with very satisfactory performance, particularly recommended for those who have good lenses, let aside after the arrival of digital, put back in the game . rn
