Lens recommendation please

[gonilho2]

I'm planning to purchase the Canon R8, mainly for personal use—capturing family moments, travel, and similar occasions. Photography is a hobby for me, so I’m not looking to monetize my work.

Could you recommend a versatile lens for both video and photography? I’m considering the RF 50mm f/1.8, which seems like a great value at around $99 refurbished. I’d also like a good option for video and am looking at the RF 24-105mm f/4L. Do you think this lens will provide smooth, quiet autofocus for video?

Also, do I need to invest in a variable ND filter for outdoor videos, or would a 2 or 3-stop solid ND filter work well with an f/4 lens?

If you have any other recommendations, I'd really appreciate your input.

Hi and welcome to the forum:

Video and travel stills photography tend to lead towards different optics.
For video, you likely want a wide to very wide angle lens,   Frankly, a good cell phone these days can do a great job for video and it's something you will likely always have.  So, for economic reasons, not getting a specific video lens would let you concentrate on the travel/general photography optic.

Certainly, I think a prime lens is going to be very limited for travel whereas something with a focal range from wide angle to moderate telephoto would be a good unit.

If cost and compactness are an issue, you can get both by going to the APS-C line of cameras.  The R8 is a full-frame unit, which will make the lenses much bulkier and generally more expensive, whereas a body like the Canon EOS R10 will cost less, be smaller and use much more compact optics to achieve the same focal performance.

If that was interesting, I would suggest an EOS R10, with the following optics:
RF-S 18-150mm IS STM lens: such a combination can be purchased as a refurbished unit with the R10 body for $1,019.00 - see: Shop Canon Refurbished EOS R10 RF-S18-150mm F3.5-6.3 IS STM Lens Kit |  These units may be over-stock, new but opened box, demo or show units, but are 'good as new' and come with a Canon 1-year warranty.

So, to help us to help you.  What is your $value budget for optics?
What are you prepared to carry in terms of bulk?

As always Trevor has asked the right questions.  

I might recommend the R8 and RF24-70 f2.8.  I might compliment it with a RF100-400.  The 24-70 L is quiet for video.  I use mine frequently.

Canon also offers a RF28-70 f2.8 (non L), and a variable aperture RF24-105 f4~7.1 if budget is limited.  Lenses are the real investment in photography.  My preference is full frame, but the R10 is a great body.

I prefer full frame any time, and like the R8, I'm trying to look at the cheaper options because the OP mentioned a cheap lens but maybe that was a misinterpretation.  I guess we need to know the budget (as usual!) to know what the OP will tolerate financially.
