Techart PRO TALMEA7 overview

  • 1Description

Transform your all-manual Leica M-mount lenses into fresh autofocus glass for your Sony mirrorless camera with the Leica M Mount Lens to Sony E-Mount Camera Autofocus Adapter from Techart PRO. Offering compatibility with the PDAF system on the a7 II and a7R II, this adapter has a mechanism to physically shift lens position up to 4.5mm on the Z axis, enabling autofocus even on manual focus lenses. This adapter will support both AF-S and AF-C focusing modes and if the lens is set to its close-focus position, this adapter's extension can be used to get macro capabilities.

For general use, it is recommended that the lens is set to its infinity focus position, enabling autofocus within its entire focusing range. Performance is optimal with 50mm lenses and wider, whereas telephoto optics will require coarse focusing with the lens before using the adapter for fine tuning via autofocus. In addition to adding autofocus, users can connect to the adapter via Bluetooth 4.0 and a mobile app in order to program lens data, up to 10 sets of which can be stored, and update the firmware. This allows for full EXIF data to be recorded when an image is taken and also enables complete compatibility with Sony's 5-axis in-body image stabilization. Additionally, it is designed to support lenses weighing up to 10.6 ounces.

Estimated Focusing Ranges
15mm: 2.6" / 6.5cm to infinity
21mm: 4.7" / 12cm to infinity
24mm: 5.9" / 15cm to infinity
28mm: 7.9" / 20cm to infinity
35mm: 12.2" / 31cm to infinity
50mm: 23.6" / 60cm to infinity
90mm: 5.9' / 1.8m to infinity

    Techart PRO TALMEA7 reviews

    Leica M Mount Lens to Sony E-Mount Camera Autofocus Adapter is rated 4.0 out of 5 by 16.
    Rated 5 out of 5 by from Works on Sony A6500 Purchased to use of the Sony a6500. B&H phone sales seemed unsure of the adapters ability to work on the Sony a6500 but I purchased it anyway due to Techart's website saying that it was compatible with the a6300. So far, I've used my Leica 35 and Leica 50 lenses with the adapter on the a6500 and it worked very well. This device is very impressive. Don't expect it to be very fast, but it's probably just as fast as most people lining up their rangefinder focus. I have noticed that it will eat battery life, so I would suggest getting a second or third battery. Overall, very easy to recommend this cool piece of tech. Good luck!

    Rated 5 out of 5 by from Innovation of the year! I couldnt understand why this is not named the most innovative photography gear of the year. Being able to convert a MF lens into AF is simply amazing. It gives me a completely new experience with my legacy lenses. You need to read through the information in order to properly use it and it does what it advertised! For the guy below, you need to park the aperture value of your camera at f/2 at all times for correct exposure and use your aperture ring to adjust the size of the iris. It has already been covered everywhere in the internet.

    Rated 5 out of 5 by from Works better than expected. Using this with my voigtlander 15mm and my nikon AI-S lenses (24, 50, 85, and 105mm) all work very well with the adapter. I find that using AF-C works better than AF-S.

    Rated 5 out of 5 by from Fantastic! Although not without faults, this thing has made my tiny camera bag (with a Sony A9) fit fast leica primes that autofocuses. I am now selling my heavy Nikon gear for good. Good: Lets you use ultra small 1.4 lenses that are sharp. Game changer Decent autofocus performance. You only have one lens on the camera at a time, so charing a single focus motor saves size and weight. Bad: My 90mm f/2 Leica glass is on the heavy side of the TechArt. You need to prefocus long lenses slightly.

    Rated 5 out of 5 by from Tech art Pro Teriffic product. Auto focus with a Leica M lens added to the great manual focus on Sony A7 cameras is a dream come true. Expensive and it drains your battery even when the camera is off. Love it anyway.

    Rated 2 out of 5 by from Techart Autofocus Has Mechanical Stability Problem I purchased this device and tried it out with a Sony A7R2 camera and 3 different Leica lenses. I noticed that one corner or sometimes two corners would be out of focus. I removed that black cover on the mechanism using a JIS screwdriver. The lens carrier, that moves, is driven by a rack and pinion geared to the motor, probably a stepping motor. The carrier rides on two linear bearings, a larger and a smaller one. These bearings are on one side of the carrier, meaning that the carrier is cantilevered and susceptible to flexing. Indeed I can see it move if I apply pressure to the lens. This means that parallelism between the lens focal plane and the sensor is dubious. Tipping the lens by even 1/1000 of an inch can cause a considerable change in focus. I think this is a poor design. The carrier should be positively supported at 3 or more points. A better approach would be a cam mechanism with at least 3 supports. The out of focus effect at the corner is worse the faster the lens. With a Leica Noctilux at f 0.95 the effect is worse, probably increased do to the weight of the heavy lens. I ran a series of tests with a Noctilux and a lighter APO 50mm Summicron, both 50mm lenses. With my particular unit the upper right corner of the image was usually blurry. The effect became small if I backed off to f5.6. However, there is no assurance that my sample is typical the units being shipped. Due to manufacturing tolerances some units could be much worse. It is a real shame that the mechanical design is dubious because the software seems quite reasonable and the focus is fast and accurate. Some people might find the device acceptable if they get a good unit and use fairly high F numbers.

    Rated 2 out of 5 by from Lens wobble Problem with Techart Techart PRO Leica M Mount Lens to Sony E-Mount Camera Autofocus Adapter Review by Norman Rogers I used this device with a Sony A7R2 and several different Leica M lenses. I noticed that different corners of the photos became blurry randomly. It seems that there is play in the mechanism that causes the lens to be tilted with respect to the sensor plane. Here is an example of sharp and blurry corners using a Leica 90mm f2.0 lens. I noticed that if I pushed on the lens it would wobble slightly with respect to the camera. I disassembled the Techart device using JIS Screwdriver to remove the two screws holding the black metal cover. The lens carrier is moved by a stepping motor that drives a rack and pinion through a reduction gear, The lens carrier slides on two linear bearings, a large one and a smaller one. That is the only support for the carrier, so it is cantilevered over quite a distance and can flex. This is fundamentally a bad design, There needs to be 3 point support of the lens carrier, probably using a spiral cam that engages the carrier at 3 points. Techart seems to have the software down pretty well, The device focuses quickly and accurately, but the corners will often be off focus.

    Rated 4 out of 5 by from Not necessary but great to have. Techart adapter is a great invention for the vintage lens lover, but it's not necessary for you to enjoy vintage lens. What it's great for is for quick snap on street, on travel that you don't want to get slowed down by manual focus and 100% sharpness wasn't crucial but catching the moment.� Do not fully relying on it's autofocus because the limitation of how much the adapter can extend limits the range it can focus. This is more obvious when you attach longer lens on, for 50mm and below, it works like a charm after you set the proper focusing distance. Therefore, you still need to manually tune the focus ring from time to time for the autofocus to work efficiently.� I pair the adapter with center focus the most to avoid the focus system get confused. Like any other electrical adapters, funky situation can happen from time to time so I suggest to use it with basic function like facial detection and IBIS to avoid them. After all, it's an great assist for nailing down the last step for your focusing ;)
