The Tiffen 49mm Soft/FX 4 Filter for Photographycan be applied to purposely reduce the appearance of blemishes and wrinkles in portraits or to apply a general soft-focus effect while maintaining overall sharpness. An array of small lenses distributed within the surface of this filter smooths fine lines and textures, which can be useful for creating a more flattering result of a subject.

This filter has a grade of 4. Grades of 1/2, 1, 2, 3, and 5 are also available where this filter type's effect becomes approximately twice as strong with each grade number increase. When higher grade numbers are applied, a halation effect around highlights can be created to further enhance a subject's appearance or produce a desired effect.

This filter is constructed from optical glass for clarity as well as color fidelity. It is made using ColorCore technology, a process that involves laminating the filter substrate between two pieces of optical glass and grinding flat to a tolerance of 1/10,000th of an inch, and then mounting to precision metal rings.

Q: 1. What is is the mm ring size?

Q: 2. what is the filter factor for this? How much light does it reduce?

A: There is no light loss when using this filter.

Q: 3. Is this a neutral density filter that can be used with tungsten super 8 film?

A: The Tiffen 58mm Nude/FX 6 Filter is not an ND filter, but a warming filter--it adds a warm amber glow to the image. Search on B&H for "58mm ND filter" to see compatible filters.

Q: 4. What is a graduated neutral density filter?Does the filter rotate? By this I mean, can I rotate the filter to high light certain areas?

A: A graduated neutral-density filter is an optical filter that has a variable light transmission. Typically half of the filter is of neutral density which transitions, either abruptly or gradually, into the other half which is clear. It is used to bring an overly-bright part of a scene into the dynamic range of film or sensor. For example, it can be used to darken a bright sky so that both the sky and subject can be properly exposed. There are typically two types of graduated ND filters, which are hard edge and soft edge. This particular Tiffen Graduated 0.6 ND filter is a feathered graduated ND filter, which means that there is a natural-appearing taper between the density and clear areas of the filter. This filter does not rotate.

Q: 5. Will this fit the Sony GM 24-70

A: This filter will fit any lens with a 82mm filter thread. When looking at your lens on the B&H website at a href= https://www.bhphotovideo.com/c/product/1222774-REG/sony_sel2470gm_fe_24_70mm_f_2_8_gm.html target= _blank https://www.bhphotovideo.com/c/product/1222774-REG/sony_sel2470gm_fe_24_70mm_f_2_8_gm.html/a please refer to the SPECS tab, where it lists the filter thread diameter as 82mm.

Q: 6. What is the difference between the digital diffusion and a classic soft?

Q: 7. Do these work on a macro lens, 18-55mm? And stacked?

A: Yes. I have been using them to catalogue my stamp collection using only the 4x but also the 2x + 4x for very close wotk on the edges to capture any minute wear and tear. I have been having excellent results.

Q: 8. Does this filter have a rotating filter ring to allow more control over placement of density in the image?

A: Yes it does. Turns easily and is well constructed. Used it successfully in Hawaii taking sunsets. It has a nice soft graduation. I've had good luck with Tiffen filters. Has the quality that I desire and meets my price point. I use my 58mm filters on a Canon GX1. Hope that helps.

Q: 9. I am looking into buying this filter for shooting sunrises and sets where the mountains and forests are very shade compared to the sky. Should I go for something darker or lighter?

A: There is no definitive answer to your question based upon the information provided. Your question depends on the difference in correct exposure value between the mountains/forest and the sky. Each .3 of ND is equal to one stop of light loss. If the difference in exposure values is two stops, go with a graduated ND .6, if it is three stops then use a .9, etc. For best results, keep a few of these filters in your camera bag with varying ND densities.

Q: 10. DO these lens work on macro lens 18-55mm?

A: Yes, you can use close up lenses on an 18-55mm lens.
