Sekonic L-398A Reviews

Simple and well made

Works well especially for monitoring lighting in various areas of a scene. No reliance on batteries, which is nice. Case and all included accessories are well made and should last a long time.

Used continuously since 1977

I bought this in 1977 for $45 (I don't know why I always remember the cost of gear but I do). I have used it without a single problem since then. I still use it today. The only issue that I have is that I wore out the leather case about 20 years ago. Recently, I thought it might be a good idea to recalibrate the meter. Guess what? It still gives me perfect exposure even after 45 years!!!

About as accurate as my standard L-398A...which means, it's serviceable once you get used to it. A classic piece that 75 years from now, photographers will admire. Reminds me of the quality and class of older Leica film cameras/lenses.

I have had a few of these light meters. They were certainly popular in the day but probably only because people lost or broke so many of them and somehow the shops always had stock of this one. While the Sekonic takes reasonable light readings, so do most of the others but without the drawbacks. I found the Sekonic to be fragile and all of mine died. The rotating head is fragile and unnecessary. The white dome is OK but not in the same ball park as the Weston Master series invercone which was the best. The insert slide to reduce light intensity is silly and gets lost easily. Again, the Weston meter did it better. When used professionally, especially on location, light meters take a beating and in my experience, this one is not built to take it.

As mentioned, this unit uses a magnet. Is it dangerous for someone that has a pacemaker or a shunt. Both use magnets.Also, what effect does this unit have on SD cards? If it can have an effect, what is a safe distance? Is twelve ( 12) inches too close?SEKONIC rep- THIS question is for you. I need a specific response please. I will not purchase without direct answersThanks.
Asked by: Harvey
Magnets will not damage SD cards, USB sticks, SSD drives, or other forms of solid state memory. Solid state memory is a completely different technology from spinning drives, which could be damaged by magnets. Don't take my word for it. Use Google. Do the research.

I have read the manual and Sekonic says that this meter must be kept away from floppy disks and similar materials. Does this include SD cards? If so, how would one do so.?
Asked by: Harvey
Floppy disks and SD cards use totally different technologies to record data. SD cards, USB sticks, and SSD's are NOT affected by magnets like floppy disks. You can safely store SD cards around the meter.

Would this be a good light meter to use for studio still life/portrait work? I use film cameras for this work.
Asked by: Ricardo R.
As long as you are measuring available light, (not flash) this is a great meter.

Does anyone know if the selenium diode in the meter wears out.Or, can it last for 30+ years?
Asked by: Harvey
You have to remember all things wear out or get old with use. Just enjoy your photograph equipment and learn to take great pictures. John
