The 40mm ND Filter from Ice is a neutral density filter with a 1000x filter factor that provides a 10-stop exposure reduction. Its 3.0 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed without overexposing your image. By slowing your exposure time, you can create motion blur for special effects or to convey a sense of movement. Opening your iris allows you to create a shallow depth of field, which can help isolate your subject. Neutral density filters do not affect the coloration of the image and are ideal for pairing with other filters.

This neutral density filter is constructed from optical glass for clarity and color fidelity. It features a slim aluminum alloy filter ring that helps prevent vignetting while remaining durable and lightweight. This filter is designed specifically for photography applications. This filter is not suitable for direct solar viewing with the naked eye, including with optical viewfinders.

Related Questions and Answers

Q: 1. Is there significant chromatic aberration at the closest focus distances, and is it sharp corner-to-corner?

A: This is sharp certainly for the price range corner to corner provided what is in frame is all on the same plane. The lens is coated and you should not have aberration provided you are focused on the closest subject and it will be sharp as long as it is not closer than the minimum focus distance.

Q: 2. How would it do as a street lens, portraits, paired with A7R r.?

A: It’s a great all around lens. If I only could take one lens with me it would be the Zeiss Batis 40 mm.

Q: 3. Being manual focus lens, focus shifting will not be automated with the Nikon Z fc, will it?

A: The TTArtisan 40mm f/2.8 Macro Lens for Nikon Z is manual focus, which means that any focus shifting will not be automated with the Nikon Zfc Mirrorless Camera, nor any other camera.

Q: 4. Craig, I'm curious as to how you determined the aperture is not f2 when close focusing? Are you sure that when you move closer to your subject that the light seen by the sensor is not changing? Have you contacted Zeiss about this? You are inferring that Zeiss is pulling a VW Diesel trick! :-)

A: The Batis 2/40 CF focuses down to 9.45", half the typical 18". This creates a magnification ratio of 1:3.3. so not 1:1 life size. There is no mention by Zeiss in their information of an aperture ramp when close focusing.

Q: 5. Is this a macro lens for Leica L mount?

A: Yes. The following lens will be made for the following system platforms Nikon Z, Sony E, Canon R,

Q: 6. Is this compatible with the Cannon EOS Rebel T7?

Q: 7. Can the distance scale be changed from Meters to Feet?

A: Yes, one can change the distance scale from meters to feet on the ZEISS Batis 40mm f/2 CF Lens for Sony E. The camera needs to be in manual focus mode. You would then turn the focusing ring 360 degrees past the minimum focusing distance.

Q: 8. is this a good lens for digitizing negatives?

A: Good lens to look at that will offer you a 1:1 life-size maximum magnification. we usually suggest 60mm and 100 Marco but the 40mm will do the job.
