Double VR - how is that possible?

Image stabilization, vibration reduction, optical stabilization - whatever you call it, the technology represented a game-changer for photographers.  I remember when it first came out, I was amazed at how my minimum handheld shutter speed magically could be lowered by two, three, or even four stops.  It was a boon to wildlife photographers as we could now use long lenses without having to resort to ridiculously high ISOs.

Nikon and Canon chose to build lenses with stabilization technology while other companies built it into their cameras' bodies.  With the trend towards mirrorless cameras well underway, the two dominant camera corporations now build their Z-type cameras with in-body-image-stabalization (IBIS).  So, you now have a choice.  When using a mirrorless camera with a VR/IS lens you can turn off IBIS and use the lens's system, turn off the lens's system and use the bodies, or use both.

Wait, what?  You can have double VR?  It turns out that you can.

For Nikon (my brand of choice), a F-series lens with VR can be operated on a Z-series mirrorless camera using the FTZ adapter (F mount To Z mount).  You can have both the lens's VR and the body's IBIS turned on at the same time.  They work in tandem and provide better stabilization than either one would independently. It's not the perfect system, but it may give you that extra edge you need for some photos.

One of the major shutter speed issues comes from subject movement.  Wildlife and sports photographers are both well aware that you can have the best stabilization system going and still end up with a blurry subject.  Put a camera system on a tripod, make it perfectly still with an electronic shutter and no movement from VR or IBIS tech and you will end up with perfectly formed branches or goalposts but blurs from the roving subjects.  

The downside to using double VR is that camera battery life will degrade at a faster rate.  With all the electronic mechanisms drawing power, having a spare battery is a good idea.  Also, since subject blur is a real threat to image integrity, keeping shutter speeds at terribly low levels is not recommended, so it turns out that it may be a waste as one system or the other could do the job.

It's good to know though that it works.  I invite you to play with the double VR concept and see if it makes a difference in your photos.  I'd like to know what you think.

Thanks for reading.

I found a black widow spider in a plant pot today

Image
The spider I found is a western black widow spider, one of three species of black widow that occur in North America.  The fact that this one has another red patch on the back of its abdomen above the spinnerettes tells us that it is an immature individual. The one thing that people know about black widow spiders is that they are extremely poisonous.  Their venom is something like 15x more toxic than that of a rattlesnake.  The saving grace is that there is very little venom injected from a black widow bite than what a rattlesnake can deliver.   The good news is that black widow bites seldom lead to death.  You are more likely to suffer nausea, muscle pain, and swelling around the bite.  Symptoms usually last only 12 hours or so.  Death may be a result in people with compromised immune systems or in the very young or the elderly.   In 2018, it was reported that there were 1015 cases of people bitten by black widows.  Of those, there ...

The passing of a generation

Image
Kathryn's mom and dad with our children, Josh and Leanne. A generation, for North America, tends to be between 20 and 30 years.  During that time a couple will give birth and raise children to see them repeat the pattern as they themselves have done.  Each generation has its own set of standards, values, and ideals based upon their experiences and culture, and some of that is passed down to their offspring.  What changes are the life experiences of the following generation and the new customs and ideals that are blended together as a couple becomes a family. Kathryn's mom passed away a few days ago, she was predeceased by her husband several years ago.  Both of them were the grandparents of my children, the mother and father of my wife, Kathryn.  It was my pleasure to know them and to love them as my own, for to me they were Mom and Dad.  And they were there to welcome my children into the world just as my children were with them in spirit when they left it...

Hang in there, things will get better.

The Svendsen Family - Eric, Samuel, Leanne, Joshua (top row), Nora, Kathryn, Chanelle, Emma If I could go back, in my mind, to a day in my life when I was really down, it would be nice to be able to see into the future.  If could see things as they are today, with the many blessings that have been given to me, it would give me hope knowing that things wouldn't always be so discouraging.   The message here is we do not know what the future holds.  When things are bad, it is hard to raise your head out of the mire to see beyond the darkness.  There are no guarantees, of course, that things will be better, but I think it is true that fortunes ebb and flow as tides do.  The trick is to see beyond the low points and not be too haughty during the high ones.  I know that, at this moment, things are very good.  What the future holds is unknown, but low and high points are likely in the forecast.   This is why taking satisfaction from the moment ...
