K&F Squared - the new 100mm square filter system from K&F Concept

MONEY and MONEY

Great presentation, awesome humor, nice job Allan!

Good video. I just started looking at a square filter deck for my film work. You didn't mention whether any color filters are available, such as a yellow or red filter for black and white work.

Other than that, you did an excellent job of covering and explaining. Thanks!

Edit: I forgot to mention that I use K&F adapters to mount legacy glass on my Sony A7Sii and my Fujifilm mirrorless cameras. Their build quality is top shelf and a demonstration that the Chinese companies can build good equipment.

My set arrived this morning; thank you for the useful (& droll) review.

It arrived with a few screws in a bag: Do you know what they’re for? Any long-term use updates?

This kit is 400 cad. Hought it would be more affordable. Ill stick with the magnetic round ones at 200 cad.

Have you tried stacking CPL + 2ND filters + GND? Does it vignette?

I bought this system after I watched a different review and what kills me is that in both cases the CPL system is tested indoors. And yeah, you guessed it right - the CPL have little to none polarization effect. Nice job!

The best intro ever!

People who watch are looking for a way to see the product either before it gets delivered and they wanna "unwrap the gift and peek". Or, they are looking for different features etc before they buy and compare. Alternatively some are also just weird like me.

What a great video, been thinking about these for awhile sold on them now Thanks Allan

Great review thanks for all the info

Very informative video. I have ordered the same set but they have been delayed in China for a variety of reasons/excuses. However, they seem to be on the move through the courier system now so hopefully I will get them soon. I am sure this set of three ND filters + CPL will serve me well but if I expand my horizons, do you know if K&F supply graduated filters using the same holder system?

Hi, Thanks for the detailed information......big question for me please, can this 100mm by 100mm square filter holder fit on a 95mm lens opening? I have a Sigma telephoto 150-600mm. I know that there are not many circular ND filters that big......that's why the square attracted my attention. Thanks for your help. DK

This is probably one of the best videos on these filters that I have seen. I have recently, purchased these filters and are just waiting to get them. You went through everything that I needed to know. Thank you so much.

I really need this system. Just need to money, the virus that shall not be named has broken me

Hi Allan, Will plain glass Lee 100mm square filters fit the holder?

Really enjoyed this filter review, Allan. I don't think the price is unreasonable for what you get especially if one is really serious about their photography. Hope to get together soon.

Allan, I am sorry to say that I feel cheated. You did not show the part where you took the lid off the box and I expect to be informed about the quality of the cardboard, including surface texture and the actual thickness of the packaging. You also failed to sniff it. I didn't have you down as an amateur - pull your socks up before it's too late.

Thanks Allan, always a thorough review. Just wondering, since you have so much time on your hands (😉 - I did watch your presentation on extreme macro photography and how long it takes you to prepare, setup, shoot, and process), you had mentioned a device to use when shooting butterflies. I’ve fooled around with a few, but would be interested in seeing what you came up with. Will you be sharing that anytime soon? Also, I ordered a Nikon stereo microscope (spending the kids inheritance), both to prepare and pose specimens, and also just to be curious with. Our kids & grandkids honestly don’t think we’ve quite lost it yet. Jokes on them!

I too Allan really struggle with why anyone would want to watch an unboxing video. I mean is their life so pathetic that watching a box being opened gives them a buzz. I mean come on people really.

That's not how you do un-boxing video. It is more of a products review video.

Very clever design , thanks for showing the system 👍

Do you really find the thumbwheel an easier way to turn the polarizer? I'm just so used to turning the front element... First video I can recall seeing where i don't get a glimpse of your nice Submariner. :)
