As an avid outdoor-nature photographer, I’ve always believed in the saying: “you can never have too many mm’s between you and a distant subject”.
Recently I decided to add more mm’s to my camera bag and purchased a Sony 200-600mm lens to accompany the Sony A7 III.
My first opportunity to use the new lens was on a trip a few weeks ago to Florida.
This is one of the first images that I snapped. As I closely reviewed it in the viewfinder I could tell that it was obviously out of focus.
The first thing I did was to immediately check the lens setting to use autofocus. It was.
I then checked the camera menu to see if it all settings were correct for autofocus.
Next I took several more photos but no luck.
They were all severely out of focus.
Disappointed, I decided to set this lens aside for the reminder of my time in Florida.
Upon returning from this trip I planned to send the lens back to the vendor for repair or exchange.
However, before calling the vendor for a return authorization, I spent a few minutes googling “Sony 200-600mm autofocus problem”.
To my surprise I found a post that was identical to my problem. When I purchased the lens, I also purchased a circular polarizing filter (huge 95mm) to help reduce glare. The individual who wrote the google post explained that his filter interfered with the lens’ autofocus mechanism. By removing the filter, his images were no longer out of focus.
So I took the filter off my lens to see if this solution applied to my problem.
BINGO. The autofocus mechanism worked perfectly and produced this image.
I’m happy that Google helped me solve my problem.
I’m disappointed that I wasn’t able to take advantage of the extra mm’s during my stay in Florida. And I’m reminded that I need to test out new equipment before I’m in the field. I’ll continue to search out for a filter which may not interfere with my camera’s autofocus. Perhaps a different brand has properties that enable the autofocus to perform correctly. We’ll see.
Anyway, I’m ready for my next opportunity to get outdoors with this lens.
I’ve been a proponent of Sony’s NEX mirrorless cameras since they first appeared three years ago. The reason is simple. The NEX series produce images comparable in quality to conventional DSLRs, accept interchangeable lenses yet are very compact. They are substantially smaller and lighter than DSLRs.
Sony’s newest model is the A6000. Although Sony has dropped the NEX moniker, the A6000 retains the same compact footprint as the earlier NEX6 and NEX7 models.
A few days before our recent extended vacation, an A6000 arrived in the mail. I used it heavily on our extended family vacation. Instead of writing a wordy review, I put together a “photo review” that demonstrates the versatility of the A6000. If you’re on the hunt for a feature packed, technically advanced and affordable camera, you should look at the A6000.
