The Tiffen 138mm Skylight 1-A Filter is a general use filter with a slight pink tint to help improve overall color accuracy and clarity. The light pink coloration helps to reduce the overall bluish cast of daylight and is especially effective when photographing landscapes and in shade.

The Sky 1A filter is also useful as a general protective filter to leave on lenses at all times. Filters help to reduce dust and moisture from reaching your lens element and provide additional protection in case of drops or situations where scratching could occur.

Tiffen filters are made using ColorCore technology, a process that involves laminating the filter substrate between 2 pieces of optical glass, grinding flat to a tolerance of 1/10,000th of an inch, then mounting to precision metal rings.

Related Questions and Answers

Q: 1. The specs state that it is an auto-focus lens. Can you focus manually if needed?

A: Yeah the manual focus works great!

Q: 2. Does this lens have manual focus available? I am wondering that If I use ND filter, how it still be able to auto focus? Please help and Thank you!

A: All lenses designed for the Sony E-mount have the capability to be focused manually. The Sony Vario-Tessar T* FE 16-35mm f/4 ZA OSS Lens has both a zoom ring and a focus ring on the lens, and the camera on which the lens is used may be set to either autofocus or manual focus, depending on your needs. Also, depending on the strength of your neutral density (ND) filter and the current ambient light level, autofocus may be possible, but if you are using a strong ND filter or working in low lighting, you may need to first pre-focus with the camera in manual mode before attaching the filter to the lens to capture your image.

Q: 3. Can this lens be used for Macro photography?

A: While it can focus to under two feet, it cannot give you true macro imaging which would require a 1:1 (life size) magnification ratio. A combination of extension tubes and or close-up lenses would be needed for macro imaging, if possible, with this lens. Distortion and image degradation would likely also be a problem.

Q: 4. Is this lens compatible with the Olympus OM-D E-M10 Mark II Mirrorless Micro Four Thirds body?

A: Yes. The following lens will adapt just fine taking full advantage of the lens features.

Q: 5. Can you use this lens on the a6300?

A: Yes, but the a6300 doesn't have image stabilization and this lens doesn't either. I use this lens on an a6500 which does have image stabilization and it works great.

Q: 6. when used on an Olympus OM D Em1 or 5 mk 2 ... does this lens work with the focus bracketing feature where the body can move the lens to focus points automatically?

A: Pavel - Yes this lens works with focus bracketing and focus stacking on the OM-D EM-1 ver 4.0. Just pick forward focal point, number of images, step increment, and press the shutter button or tap the LCD screen.

Q: 7. Can't decide between the Sony Distagon T* FE 35mm f/1.4 versus the Zeiss Batis Lens 2/25 for my Sony A7iii (for street photography and portrait)?. Any input is very much appreciated! - Thank you!

A: They are quite different lenses, The 35 mm is a great lense with awesome bokeh, if you want something wider than a 50 mm but with a natural look, it's a great lens.The 25 mm will be even wider, but I think it's starts to get a more pronounced wide-angle look, it's ok if you want to have the environment around your subject, but if you get to close the distortion might be less pleasing.

Q: 8. 2. This lens has VR. Nikon Z6 have the VR system in the sensor. How those two VR systems will work together?

A: Z mount lenses with VR will add an axis to the vibration control. This gives the camera a 5 stop rating.

Q: 9. How will this lens compare with an equivalent F lens on Z6 using the FTZ adapter?

A: The Z lenses have a new updated design and they are slightly sharper than their equivalent Nikon F mount lenses. Also Nikon does not have a lens with this exact focal length in F mount. They have the 28-300 that is not as wide, but has a longer focal length. It is heavier at 800 grams. This lens weighs 570 grams.

Q: 10. Is this lens considered to be a flat field lens (i.e. for copywork of 2D art)?

A: Yes, it is a flat field lens.
