The following opinions have been automatically translated with Microsoft Translator. | Voigtlander Super-Heliar 15mm f4.5 ASPH Pros: Compact, light, framed field Cons: Problems with many digital cameras, field curvature and vignetting. Opinion: This lens is part of a series of optics produced by Cosina at the end of the years ' 90 to relaunch the historic Voigtlander brand after acquiring it. Designed for 35mm rangefinder cameras, the lens is adaptable to mirrorless and digital Leica, but in most cases it creates problems because of the sensor filter, which causes false colors in the edges of the image. Its problems in this regard are particularly known with the Sony mirrorless, both full frame and APSC. On Fuji equipped with Xtrans sensor This problem should not occur (beware though, there is no definite information about this!). I have experienced it on a Fuji XM1 and I have not had such problems. Another known problem is the curvature of the focus field, which causes poor sharpness at the edges relative to the center. On APSC This problem is rather limited while on FF it is really serious. The vignetting, inevitable in such small lenses with this focal, on APSC is easily correctable, while on FF is really heavy. There are two versions of the Voigtlander Super-Heliar 15mm f4, 5 ASPH, one with LTM screw-mount (version I) and the other with bayonet M (version II, the latter if I am not mistaken has the Leica rangefinder coupling). Both are identical from the optical point of view and give the same problems with the digital ones. Version III is designed for digital Leica and is almost identical to the Sony E-mount version. These last two versions do not give color problems. sent on May 04, 2019 |
 | Canon PowerShot SX130 IS Pros: Low ISO detail, good focal range, macro and color modes, decent battery and good stabilization Cons: Noise at 200 iso, wide-angle distortion, non-existent burst, sharpness loss at the edges to all tele. Opinion: This camera is one of several canon compact cameras that allow manual setting of times, diaphragms and ISOs. Although you can not compare the quality to that of machines from the largest sensor, at low ISO images are more than dignified and have beautiful colors (the famous Canon colors). The camera also seems to be robust and reliable, used with good AA rechargeable stylus has an extremely dignified battery life (given that I did not use it for video). Knowing the limits you can also do shots that many do only with more serious contraptions, the stabilization seemed very valid although not based on 5 axes as the current, I shoot at all wide angle in interiors even at 1/5 of second without tripod But it also depends on how much you can stand still. The wide-angle macro mode has a good magnification level and comes in handy in different situations. The lens visibly distorts to the shorter focal lengths and must be taken into account. Landscape photos are only possible at 80/100 ISO, already at 200 many details you start to lose on long distances. 400 and 800 ISO are usable are for neighboring subjects and portraits. All tele do not recommend to use the lens to F5, 6, better close it and risk a bit ' diffraction because otherwise you have a noticeable vignetting and loss of sharpness at the edges. sent on November 04, 2018 |
 | Fujifilm X-M1 Pros: Dimensions, lightness, display, high ISO resistance, quick controls, possibility to use vintage optics, tilt flash Cons: autofocus in low light, handle, power button Opinion: In my opinion, this small and light machine allows you to experiment a bit 'of everything you can do in the world of photography. The Xtrans sensor allows you to take good pictures even in low light conditions where you have to pull up the ISO sensitivity, without losing too much detail due to the noise. The commands are few and essential: in manual mode the large dial controls the exposure time, the small one (vertically) the diaphragms of the XC lenses without aperture ring and the fn key allows you to quickly change ISO. If you use manual focus, the small dial can be pressed to activate the magnification on the display. For those with small or medium hands it is perfect. Too bad only for the little pronounced handle and the awkward and sometimes a little hard key. I use it with the two XC lenses 16-50 and 50-230 and vintage Canon FD and LTM manual lenses. The use with optics too big and heavy is obviously inconvenient, it is a body machine to usemainly with small and light lenses, not too long focal length. The display impressed me for detail and visibility even with lots of light, it tilts 90 ° downwards and upwards, allowing you to photograph over the crowd or use low perspectives without spreading on the ground. The battery has a standard life for a mirrorless (not exceptional then), it is good to have 1/2 spare if you want to take a lot of pictures. I use the flash a little but the possibility offered by the pop up flash that can be directed upwards to light up the rebound is something that many more expensive machines do not give. Autofocus can misfire in low light if you do not find anything bright enough to hook it on, thankfully these are quite rare situations. Vote 9. sent on January 09, 2018 |
 | Fujifilm XC 16-50mm f/3.5-5.6 OIS Pros: Lightness, sharpness, small dimensions Cons: Distortion, backlit reflections Opinion: A good little zoom, I use it for 2 years on the X-M1 and I have never disappointed for clarity and detail, which are placed at a good level at all focal length even at full aperture. The only flaws I found are the poor resistance to reflections (flare) in backlight, especially in the night photos with the street lamps in the frame (even with its lens hood mounted) and the strong distortion at the wide-angle focal points. On this last aspect I wanted to specify that to work raw raw use therapes, which has no self-correction profile related to this goal. However, the shorter focal length compared to the usual 18-55 is useful in different situations. As for the non-metallic construction I do not want to say much, certainly the fact that it is plastic makes it more fragile but also lighter, but I tend to change often I have not yet broken. sent on January 09, 2018 |
 | Jupiter-3 50mm f/1.5 Pros: Colors, blurred, compact size Cons: poor sharpness at the edges, minimum focus distance, materials. Opinion: Born for Russian camera Fed, Zorky and Kiev, the Jupiter 3 exists in two types of graft: The M39 (the old Leica screw graft, also called LTM) and bayonet for the old Contax telemeters (of which the Kiev cameras were a copy). I have the M39 version, the dimensions are perfect for a small mirrorless; the construction quality, on the other hand, is affected by the somewhat fragile materials (aluminum). It is a very suitable lens for portraits and all those situations in which you have to highlight the subject by blurring the background. The bokeh is particular, a little swirling and with perfectly circular light points even closing the diaphragm. If you want to have everything sharp but it is not very suitable, and it is a shame because the lens saturates the colors and makes them very pleasant for landscape photos. Another flaw is that to use it in close ups you need to use extension tubes, since the minimum focus distance is one meter. sent on November 04, 2017 |
 | Manfrotto Pixi Pros: Compact, lightweight, economical rn Cons: It does not allow you to use the vertical framing Opinion: Excellent tripod travel, combined with a compact or slightly mirrorless allows to take long exposures in almost precarious positions. The more you use the more you discover situations where a compact tripod has something to say. It does not have the articulation of a gorillapod, but if you study the situation well, you can place it in unorthodox ways to walls, parapets etc. I could also use it vertically, holding it with his hand on a wall. It 's not yet been designed for this type of shot, and this remains its largest extent. sent on January 26, 2016 |
