Recommend a gradient mirror

Give you a discussion of others for your reference:

Face life with a smile: Considering the great contrast between the sky and the ground in landscape photography, I want to buy a gray gradient mirror. Please ask the teacher 10 1 what brand to buy. A friend recommended Gaojian, so what specifications do you need? In addition, is there a round gray gradient mirror to choose from? Can you tell me something about the use of gray gradient?

Jiang Chuanyu: You can choose the filter coefficient of Gaojian gray gradient mirror1(120)1.3/2 to compensate the filter coefficient of 0.3/ 1 or gray gradient mirror (middle) (121). To use a gradient lens, you need to buy an adapter ring corresponding to your lens aperture and a sleeve seat.

Ldc 10 1: It is best to use 77mb+W multilayer coated gradient mirror, which is about 1400 yuan. Gao Jian's * * * comes in two sizes. The advantage is that the mirror frame is unchanged and various lenses can be replaced frequently. But the volume is relatively large, so if you don't use many lenses or have many lenses with different calibers, you don't need them. Polarizers can be used to darken the sky.

Gaojian lenses are divided into three series, A, P and X, with sizes of 66x72, 83x83, 130x 170 respectively. They are suitable for lenses with different calibers, with matching sockets of different sizes and specifications and lens rings corresponding to specific calibers. If you have a 77mm lens, you should use the P series. The lenses are inserted, just like the frames measured when you wear glasses.

There are three kinds of lenses: ND2, ND4 and ND8, which reduce the light by 2 times, 4 times and 8 times respectively. There are also variants: full-scale gray transition and soft transition, both of which are ND8. The choice of lens depends on the subject. For example, it takes 8 times to shoot scenery with strong reflection, such as snow-capped mountains. If there is no specific target, 4 times is enough. In addition, I must remind you that although Gaojian's lenses are very cheap, they are not multilayer coated.

Nanxi river 007: LDC 10 1 Hello, teacher. I want to buy a B 10 W multilayer coated gradient mirror, including a set of seats and a connecting ring (with Canon 24-70mm2.8L). I can't get the best at this price. Excuse me: where can I buy it? Thanks in advance.

B+W and Kengo multilayer coating gradient mirrors are the best quality brands. 77 mm diameter costs more than 654.38+10,000 yuan. This is a fixed thread diameter of 77 mm, which does not need a sleeve seat and a connecting ring, and is screwed at the front end of the lens like a polarizer. Moreover, to distinguish between 50% and 25% (transmittance), you need to decide which to buy first.

Nanxi river 007: I bought a medium gray gradient mirror with B+W25% in Delida. The price is 880 yuan. After the lens is installed, the horizontal position of the gradient boundary line cannot be seen directly from the viewfinder when rotating the outer frame of the middle gray mirror. How to directly see the horizontal position of the gradient boundary line and the real-time effect after rotation adjustment in the viewfinder? Thank you for your suggestions, Chief 10 1, rainforest moderator, film friends.

Ldc 10 1: The gradient lens does not need to be adjusted in the viewfinder like a polarizer, just put it on the lens to see the direction.

Yvlin: Although the gradient lens is better than B+W, it is convenient for external use. Since it is called gradient gray scale, there is no obvious boundary after the filter is installed. If you can see it with the naked eye, the film will have obvious boundaries. In addition to the difference in depth, there are two kinds of boundaries: hard boundaries or soft boundaries. You can merge two blocks and adjust the gradient position.
