The following opinions have been automatically translated with Microsoft Translator. | Pentax HD DA AF 1.4x AW Rear Converter Pros: Construction of excellent workmanship and materials. Cons: Price a bit 'high Opinion: I purchased it for use with the 60-250mm. Before using it I did the firmware upgrade as suggested by Pentax and sharpness seems buona.rnL'ho also tried the 70mm f / 2.4 fixed that maintains excellent nitidezza.rnVolevo add that you can also adjust the duplicator the fine focus, which I did with both 70mm and with the 60-250mm and the adjustment is memorized for each objective that is coupled to this multiplier. So I think the Pentax has done a great job. Especially considering the fact that for autofocus is provided for both the operation with the engine optics or through the PTO of the reflex. The camera automatically recognizes and selects the AF faster depending on the perspective utilizzata.rnNota painful price that I think is higher by at least 50 euro to the concorrenza.rn sent on October 31, 2015 |
 | Pentax SMC M 50mm f/1.4 Pros: Small in comparison to the same focal length and optical brightness designed for digital, but despite its size is very bright and excellent quality, especially when used with a film camera or a digital Leica format. Cons: The high quality that can be found by using it with a reflex sensor size 24x36mm decade if used at full aperture with an APS-C. But already diaframmando 5.6 fixes the problem at least parzialmente.rn Opinion: It 'a great lens that I have since I started taking pictures with a film SLR Pentax and is bright enough to focuse hand with a digital means formato.rnSe is used with a digital SLR Pentax loses only partially autofocus. I wrote in part because not having the PTO for the motor focus must focuse by manually rotating the focus ring to focus, but with a Pentax when you reach the point of focus the LED confirmation and also hears the tone. Then, I always refer to the 50mm f / 1.4 mounted on a Pentax camera body, if we set the mode catch in focus, we can be sure of perfect focus by rotating the lens because the shutter automatically when it reaches the set- fuoco.rnUn last consideration, but perhaps this is only valid coupling it to a Pentax, if we set the M mode and move the lever to the right to coax shutter button would have the digital meter displays in mirino and so we could take pictures as it was once. Latest note: in automatic mode aperture priority, as there is no electrical contacts, always will shoot at full aperture with the ring positioned at a different point from f / 1.4.rnConcludo: Pentax SLR with this view is automatically stabilized, obviously selecting menu from the focal length 50mm.rn sent on December 12, 2014 |
 | Pentax K-7 Pros: Strong structure. I drop the bag on the tiles with attached 17-70mm which is not a lightweight. Yet it has not suffered any damage. He had only moved the memory card that I removed and reinserted and the camera continues to operate in meraviglia.rnNel white balance manually, to me, is more accurate than the K5. It 'was the first SLR in history to take HDR directly on camera.rn Cons: He feels the weight of years and the sensor Samsung, outstanding up to ISO 400, the noise shows already after the 600-800 ISO. Opinion: It 'was my first DSLR bought especially given the opportunity to continue to use the old lenses without electrical contacts and no autofocus. With the beep / visual K7 you can focuse on hand and be sure to be in focus when you turn on the LED confirmation. In manual mode, pressing the lever over the ignition ON position appears as if the light meter in the viewfinder to the camera as if it were a reflex pellicola.rnIl optical stabilization system works perfectly well on the old obsolete optics with screw. Obviously adapter K.rnE 'small but ergonomic grip makes it feel like an extension of your arm. What else: when you exit the market had superior performance to a direct competitor D90. On the used market is not he who bought it does not follow trends and prefers to keep it. Coupled to 70mm telephoto portrait I used with this light at full aperture and 1/20 "freehand providing photos to say the least eccezionali.rnUn last thing: tofference of other cameras of the same level of competition that do not have it anymore, still has the connection for the flash studio.rn sent on November 20, 2014 |
 | Pentax HD DA 40mm f/2.8 Limited Pros: Remarkable performance in detail and also a nice blurry despite being only a 40mm f / 2.8. Cons: I use it this summer and I have not yet found defects. Opinion: I think it can easily replace the more expensive 50mm f / 1.4, but I consider the most versatile. My nude photos, since I bought this lenses are almost all taken with the 40mm except for the first close-ups where I prefer to 70mm.rnTornando 40mm is so compact that I consider perfect and unobtrusive when you want to take pictures discreetly rn sent on November 16, 2014 |
 | Pentax K-3 Pros: I think it is the best overall among APS-C currently in production. Cons: Perhaps it would be enough to 20 megapixels and have a better seal against noise at high ISO where in comparison with the sensor of the Fujifilm X100 is not just history. But you know the APS-C Fujifilm are from another planet. Opinion: For Neronemn who wrote: rn "I wanted this very machine, Dovo reading many reviews, I have a Canon 6D and 600D but I wanted to try this machine. I decided to purchase and I did it together with a 17-70 f4 SMD DA. At first all is well, it seemed, then they started disappointments, photo two out of three is not completely in focus and when you croppa disappointment increases. I have not slept for two nights to figure out the problem, but I had to change my mind and I started to hate the K3, unfortunately, until they decided to return it and opt for a 70D, far less attention to detail but I must say that the photos are great, all of them. What a let down and think that the Pentax hoi done a blizzard for it. I do not know if I would recommend it. "rnrn rn rnrnPosseggo a K5 and earlier K7.rnEntrambe a good SLR, but the 17-70mm f / 4 is not up to the quality of fixed lenses. Especially the 70mm f / 2.4, which costs less, is from another planet. So if you were disappointed by your pictures, I would strongly suggest using the K3 coNo optics fisse.rnCiao sent on November 14, 2014 |
