A few IR shots taken with the SD1 Merrill and the 18-35 mm lens. These images were taken at a local park in 2014.















Enjoy! ;)

Nice ... what filter, Larry?

Interesting the difference between #1 and #2 caused by the skies; by which I mean that the foliage contrasts less against the clouds.

The filter is a Hoya R72 or 720 nm

I think that is true Ted and the foreground trees are not leafed out as much as the trees in the first image. Thanks for the comments, appreciated. ;)

Thank you microscope for the nice comments, very much appreciated 😎
 
Very nice Larry, is it safe to assume that the 18-35mm is safe from hotpots? I ask as l have decided to buy one. I think for my current project it will be beneficial due to the max aperture and l have concerns that SA lenses will become scarce over time. l thought l'd grab one now as l have no plans to upgrade my SD Quattro. Being hot spot free would be a big benefit to me as l intend to shoot infrared more next spring/summer.
 
Could you say something to the metering?

I have found that the blue sky (dark in IR) is significant noisier in the first image ISO200 than in the third ISO100. The noise level in the first seems more than expected by the ISO difference. Was the the first image underexposed? Did you lift in post? I guess your finder was dark. Do you autofocus w/o filter and than setup the filter?

For what it's worth, it is listed as a "good performer" here:

Thanks rf-design for the comments and questions, I will answer as best I can since these were taken 2014 and on different days. I normally shoot the SD1 Merrill at ISO 200, but when shooting IR I found that ISO 100 works better. the first image may have been under exposed a little.

I manual focus without the filter, set the exposure and put the filter on to shoot. This seems to work the best for IR. I on occasion will use a incidence light meter to get my exposure.
