TTArtisan 100mm F2.8 Full Frame Bubble Bokeh Lens Camera Lense Compatible with M42 Mount Camera Lens

I bought this for my Z8 and I am using a cheap $13 M42 to Z adapter I bought on Amazon. Love the bubble bokeh and find myself lining up shots just to include the bubbles. I understand this will work on my Fuji GFX 100s so I will need to obtain an adapter for that camera too. The lens can get sharp from f4-f22 but that is not really what I bought it for. Seems well made and well finished.

The lens is very solid, good metal construction. I just received the lens and have only taken a few quick snapshots with it. I'm loving the bubble Bokeh and can't wait to do more shooting with the lens.

1) optically, it delivers as advertised. It's a very nicely made Trioplan lens. The soap bubbles are there in the blur when you want them. It's crisp, even wide open - not quite as sharp as some modern lenses, but plenty sharp enough. This is a very competent lens. Of course, it's a Trioplan, so it has the flaws of a mid 20th century design, like bad flare and soft corners (unless stopped down), but it's a modern one, with no haze, fungus or other flaws. Especially at the price, this is darned good.2) it's solid, the focus movement is lovely. The aperture ring has positive clicks, and is light. At this price, it's MORE than good enough. It appears to be extremely sturdy.3) This is designed to mount 90 degrees counterclockwise, seen from the filter end, when fitted to a properly machined M42 mount. It's usable, if odd, if fitted to a non-adjustable M42 mount. If fitted to a rotating M42 adapter, which is adjusted to match, it'll be fine.

A little soft wide open but for the price it’s actually incredible for an interesting bokeh look. I have this on the Nikon z8 with a macro filter on it. Well worth it!!!

The lens has character, and that's good, though it is impossible to shoot into the light without a lens hood or shade and there appears to be no coatings on the outer lens element. My biggest problem with the lens is that the mount is 90 degrees off so that the aperture marks and focus marks are off to the side of the lens... which, for a manual focus lens that uses an M42 adapter is a real problem that should be fixed by TTArtisan right away.

The lens itself seems to be okay but when I order what is supposed to be a brand new lens and it shows up in an obviously opened box and re-taped shut, it makes me wonder if it is new. TTArtisans puts a tamper proof seal on the box and this one had been removed leaving "Void" all over where the tape had been. Also, the lens cover was scratched on one side.

Excellent packaging and quick delivery. It's an Impressive shiny new manual lens and my first M42 lens. I experimented on a sunny seaside day, later with flowers, early morning and sunset. But it remains way too early to fairly evaluate. The lens required getting used to because I haven't shot this type of lens before and the lens adapter required minor adjustment to line up Len's marks. No big deal. The adapter came with tools and adjustment was expected per my pre-purchase research. I have a Full Frame Sony A7Riii Camera that features In Body Stabilization, Focus Peaking and Back Button Focus easing manual focus. I got some cool bokeh effects on a hot sunny day at the beach. I like it a lot. But I lack of a lens hood is hampering full effect. Will see after I add one. I am testing various 49mm filters to handle glare for now. Looks like a keeper.

Optically what I expected from the reviews. But one thing that's not mentioned is that it mounts upside down when mounted on the camera. Of course, ttartisans says you can adjust the mount to rotate the lens to the correct orientation, but that only works with some mounts. If you use any mount that cannot be adjusted, the lens will always mount in the wrong orientation.
