A couple of days ago, I went up on the Blue Ridge Parkway to recheck my Nikon lenses for use with the Sony camera. I wanted to find out which lenses no longer would be needed and which to keep. A Sony adapter allows this.
My favorite Nikon lens has been a Nikon 300mm EDIF f/4.5 that I’ve used for most of the images that have been published, so it’s pretty good.
However, I haven’t been able to use it with much success on my Nikon DSLR’s because of losing my electronic connections. That is still the case with the Sony’s; but, I still wanted to compare it to the native Sony lenses.
Results? Foreground sharp, but background buds not so much, as I wasn’t able to increase the depth-of-field using the adapter. The image you see above is with the Sony 18-200mm lens where I was able to adjust the DOF. The Nikon Lens is going to KEH Camera which buys used equipment. Time for retirement.
The interesting thing was that as soon as I sent the above image to our Lens Lugger group to alert them to the bloom of the Pink Shell Azaleas, I received comments. Which camera did I use to photograph this blossom? It was made with the Sony A7II using the Sony 18-200mm 3.5-5.6 lens, which is a cropped sensor, not the full frame.
Yes I now have a full frame Sony, also. I finally broke down and got it. The first thing I noticed, was when I use it with my non full frame Sony lenses, how sharp the images were. Not that the A6000 is a slouch, as I been having published with that also, but I hadn’t expected the marked difference with non full frame lenses.
Review of Field Work
While doing this comparison shoot, I was reminded of something I’d like to pass on. First, I checked about wind conditions before going into the field. Only 1-2 mph from 7AM until 9AM, then increase to 4 mph. That is enough to make the image blurred in low light conditions. Sure enough, the breeze showed up right on schedule. Amazing.
Generally we need about 1/250 of a second to stop movement of the flowers in a breeze. The above subject was photographed at a shutter speed of 1/20 sec. Many images were trashed because trying to beat the odds, waiting for a quite moment, then hitting the 3 sec. delay shutter release button while on a tripod. What to do?
- Have a remote control to bypass the shutter release 3 sec. delay.
- Use something to block the wind.
- Increase the ISO, which might also cause additional “noise” in the image. The image above was shot at 50 ISO in an attempt to maximize the sharpness.
- Use a reflector to bounce more light into the area thereby increasing the opportunity to increase shutter speed.
- Use a Flash.
Using a flash can be a handy solution. Even the small, on camera flash may produce enough additional light to fall on the blossom, for that moment necessary to record the image on the sensor. You might have to under expose the image a bit to compensate and not over expose the image. Or use a defuser over the face of the off camera flash. Or turn down the intensity of the flash if your equipment has that feature.
