TT Artisan 17 mm f 1.4 APS-C lens connection MFT mount wide angle lens with manual focus

For the price this lens is a complete no-brainer. There is simply nothing that can compete at this price on terms of quality and value. It is a great lens.The lens is extremely well made, metal and put together very well, it feels solid in the hand and both the focus ring and aperture turn smoothly and accurately. The aperture click position does seem ever so slightly offset from the numbers but this is not a problem, just an observation.The lens is tiny, resembling a pancake size and ideal for just taking anywhere. The manual focus works flawlessly and I use focus peaking which displays the focused areas in a different colour. This results in very fast and accurate focus / take shot sequence. In fact I have grown to like using this over autofocus in many situations as I can actually see what is in focus rather than letting the camera decide, it actually feels no slower operation to manually focus now.Some people have said this lens is not as sharp or has colour flaws compared to brand name lenses. I will have to disagree with this. The lens is super sharp at f2.8 or greater, even f2 seems ok most of the time to me and of course gives a heap of blurry background if that what you want. In average light outside the results are as good if not better than many of the brand lenses (which are also very good).To produce a lens of this quality for this price I don't know how they do it. One observation is that the bayonet fit is quite tight when placing and removing on a mount, you need to be careful what force you use and preferably grip the lens very firmly.One possible negative of operation is that you will need to use both hands as you will need to manually focus. No one handed shooting I am afraid unless you are sure of your focus beforehand. The second negative is that this lens is not connected by any electrical contacts so there is no recording of any lens data in the digital file - so no lens aperture / focal length etc.As can be seen from my photo the lens looks great on a small body like the Panasonic G100. It just "feels right" on this type and size of camera. I have found from experience if you like the look and feel of the camera and lens you are using you will probably take better pictures as a result.If you are considering getting this lens I can highly recommend it, the pictures it can produce are fantastic and the whole feel of the lens makes it a joy to use.

The lens is very nice, it produces a sharp but soft retro looking imagine when combined with proper camera settings. It’s slightly slow to use compared to auto focus lenses, and takes some practise to learn to use properly, but when you learn to focus it right and tune color settings nicely in your camera, the lens draws beautiful images. I can warmly recomend this lens.

It is a great lens for the price. It looks really nice on my Olympus camera with the silver stripes and has a fast F1.4 aperture. It has great build quality with smooth focusing, and I love the clicked aperture which is rare in Chinese manual focus lenses.However, the focus marking is not very accurate. The actual infinity focus is at the 5m marking of the lens, which is a bit annoying. The lens is a bit soft wide open, and you have to stop down to F2.8 to get sharp results. Lastly, the lens is a bit on the heavy side and doesn't feel very balance on the camera.The lens is not perfect, but it is excellent for the price, so I am giving it 5 stars.

I bought this for interior scenes on an arthouse feature film shot on a BBMC 4k, I do have a set of cinema primes but not at f1.4. The results match perfectly with glass costing 4 or 5 times the price. If you use outdoors get a lens hood. Because its designed for photography and has a vintage tapered body you wont be able to use standard pull focus. Amazing value.

Good value and well made but as it's manual focus it needs to be focussed very precisely to get the best results, if only it was made with the electronic links to the cameras autofocus systems to enable it to focus automatically.

After looking at various lenses over a few weeks, watching videos and falling for the rave reviews I decided to go for this lens. How disappointed was i after putting it to the test. Close up shots were ok, but scenery shots were very, very poor. Out of focus despite using the fringe focusing method on my GX9. It’s a solid metal lens, well engineered, but that’s no benefit if it’s not doing what it’s supposed to do and that’s produce a sharp image.Returned to Amazon.

This lens claims to give 180 degrees field of view on APS-C cameras. From that I expected around 125 degrees on an MFT camera. On my MFT camera I get about 100 degrees, very disappointing.

Centre is quite sharp even wide open, but to get sharpness across the frame you need to stop down to f/5.6 or f/8. Even then it is not the sharpest lens at the edges but perfectly adequate. For most situations where you are shooting wide open the emphasis is on the centre of the image anywhere - e.g. with flower shots, so soft edges are part of the desired effect. I really enjoy using it - focusing is straightforward with the aid of peaking on my EM5iii. The construction seems to be very solid. Extremely good value and enjoyable to use - 50mm equivalent is just right for me. If you already possesss the Lumix 20mm f/1.7 this lens may not be an essential purchase, but at this price you can indulge yourself.
