The 1.4 TC works very well, especially on the A9.
Avoid the cpol because the light loss is great. Ok on a tripod with a 100mm filter system
like Nisi or Haida.
The 100-400 with tc is the lens of choice for travel when a long zoom is needed, heaps smaller than 200-600
and 400 2.8.
We just purchased the Sony a6600 and did a 40 min. recording with the below specs. The problem, the camera split the recording into 3 separate files each approx. 1.97 GB in size. Is there a way to have long recordings with just one file (40min to 50min long)? We need to upload to YouTube as one continuous recording.
-SD Card SanDisk Extreme Pro 128 GB, 170 MB/s formatted with exFAT but with the option to format to NTFS
Any help appreciated.
