You are extremely thorough. Do the lenses drift once you have micro-adjusted them? Do they drift enough in different temperatures to need microadjustment? Perhaps you use very large apertures a lot?
They do seem to creep very slightly over time and I think temperature is the biggest factor because I tend to use four to five lenses regularly and the wear is shared, they are all quite new. I had very minor focusing issues with a couple of lenses either focusing just forward or behind for each respective lens and I decided that if I'm investing time and effort and often money into a shoot which might have a load of planning involved I need to be on my game. When one considers I can be shooing on location in 28 degree heat then later in the year -2, I think it's worth the effort to check and adjust.
I'm probably bonkers.
Yes, I often shoot with an aperture f/1.2-1.4 and focusing is critical at those apertures. I do use manual focus when the camera wants to do something I don't, and close up I sometimes adjust focus and move the camera to achieve focus for stationary subjects.
You must have great cropability with the 5D, right down to 100% I imagine
Yes the cropability is very good with the files from the 5D4, but we always want more
overall it's a great package with superb dynamic range.
Sometimes they stick around. With flies, if you can find one blowing a bubble there's a good chance (in my experience at least) that it will be around for a while as long as you don't disturb it. They tend to slow down late in the day too, although if you are using available light that might become an issue. That said, presumably you can use very high ISOs with the 5D IV.
Yes, agreed some of them almost have to be nudged by the lens hood to send them on their way. If I were to be doing a lot of work with flies I'd perhaps get a net and cool the flies down first so they feel inclined to hang around until they warm up
As far as high ISO's go, yes I do crank it up as required but having used less able bodies for a good while I still find myself using only what I need and with a fast lens I tend to set it at 50 a lot of the time on bright days or when using lighting.
I did an indoor shoot a while back and used it at ISO 2500-3000+ with no noticeable issues. Would have killed the images with my previous bodies.
Once again thank you for you time Nick, very much appreciated. I was hankering for a 16-35mm and after doing some close up this week, more by destiny than actively going after it, I'm kind of trying to justify getting the 100mm f/2.8 macro instead.
Kind regards
Tim
