I purchased a Canon EOS R the other Day with the RF 24-105 lens, I also purchased a really nice Manfroto Tripod, some memory cards, and a DJI Ronin SC gimbal. I am really excited so my question to you guys what would be the nest thing I should be thinking about? I assume it would be to buy some filters and or a EF Mount adapter and a second lens? I am leaning more towards a Ultra wide angle lens what would you guys recommend and why?

And if you disagreee and feel I should be saving and putting my money into something else please do not hesitate to tell me I would greatly appreciate it. I just want to make sure every dollar counts, I am n to made of money and I have spent thousand of dollars to get serious about this. Thank you in advance I look forward to hearing rom you.
