I have a Canon 70D with an 18-35mm ART from Signa attached, a very massive and heavy lens and this ball head takes it without issue. Based on this, I can take 99% of camera / lens configurations of enthusiast photographers!

As someone who is heavy into video production I am extremely familiar with diffusion filters. I have used them on various projects for quite a while now. What makes this filter from K&F Concept so special besides the awesome look is the magnetic filter system. Having recently purchased a few more different magnetic filters this concept has quickly grown on me and I have almost switched all the way over.

The Diffusion filter does exactly what it should do, no more or less. The filter gives tons more character to your digital images from your DSLR. The magic of the filter is that it causes the highlights (especially light sources) to quite literally glow. The effect adds a dreamy look of halation to the highlights, a common look of feature film styles. I have included a screengrab of a music video I shot using the filter.

In the box you get the diffusion filter, an adapter ring and the lens cap. All of these items are magnetic and snap right into each other. You simply screw the adapter ring into your lens thread and then you just snap the diffusion filter on within seconds you have the dreamy look you have been waiting for.

This filter fits perfectly on the Sony SEL-35F18 standard lens (fixed focal length, 35mm, F1.8). After buying the lens, I screwed on this filter to protect the lens from dust, scratches and other external influences. Recommendation.

recently bought an older lens (35mm 2.8f) from GDR times that has an M42 mount. The aim was to connect this lens to a Nikon D750 - and, thanks to the adapter ring, with success! The adapter can be easily screwed onto the lens. It neither hooks nor is it difficult to turn - I am really positively surprised by the adapter. Attaching the adapter to the M42 lens is really very easy. In addition, the lens attaches very well to the camera! Personally, I think almost 17 euros for a metal ring is a bit exaggerated, so I have to deduct some from the stars. However, it is nice that there are such tools to be able to use valuable old glass from the days of the GDR! :-) Thank you Amazon for the fast shipping.

The adapter is absolutely valuable and solid - I don't know what could be done better for more money. I use the adapter with the W.Rokkor-HH 35mm 1.8 and the MC Rokkor-PF 55mm 1.7. On the lens side you can see a slight play in the direction of rotation, BUT this play is also present on the old Minolta camera. So NO defect of the adapter.

use the following other lenses on my Sony A7 Mark III: 24 - 105mm 4.0 | 16 - 35mm 4.0 | 85mm 1.8 | Just so you have references for my review...I think the lenses I listed above are beyond reproach. I was skeptical about the Samyang at first. I bought the lens because I ... a) wanted a light fixed focal length that forces me to use this really "cool" 35mm;-) b) wanted a light combination c) I'm still relatively flexible with it ("Street " not necessarily only people, but in the city) possibly also portraits (not classic, just more reportage) ... the fixed focal length should of course be quite sharp (but sharpness is really not the most important thing for me when taking photos, just a side note) d) Face detection and eye autofocus would be very nice because then I can focus on composition The Samyang really has all of those things. That's a really good lens! It is of course a value for money monster! The only downside... no metal, but plastic. But I can do without it. It would be "stupid" the other way around. Metal and for that a cucumber of lens, right? Here you can really access without hesitation. It's a lot of fun, the autofocus works really surprisingly well...I wasn't really expecting it.

The filter works best if you have a lens that is greater than 35mm. When the lens is too wide angle is when you get the X looking area

I think it's a well machined adapter that works very well.. I tried it on a M42 35mm and a 135mm lens .. I was surprised at the quality of images I was able to get on my Sony A7ii and Sony 6000... Well worth the investment.
