Advantages of Full Frame?

[a77Minolta]

Good morning everyone, can someone please tell me what the advantages of full frame vs APS-C I regards to using FF A mount lenses?

I’m stuck using older gear as I’m neither a Pro or serious shooter. I upgraded to an A77 from an A330 and love it. As the the prices on used A99’s and A99ii’s may soon be in my reach, I’m wondering if it’s worth the step up.

I understand there’s a crop factor but I’ve not ever used a FF body, so what does it really equate to? Are we talking marginal, or tremendous difference?

I have some good Minolta glass and am seeking more.

Basically, if you have a 50mm and a 35mm, take a shoot with both at same distance from the subject. Using a full frame with that same 50mm will give you the same bokeh (since it's the same lens) but a framing a very little wider that the 35mm on aps-c.
Once you figured that out, check the performance differences of the 2 bodies by comparing reviews.

If you have FF glass, you'll get a lot more from them and won't be carrying useless extra glass anymore.

For what subjects and contexts?

landscapes and city scenes. Possibly street photography.
What I’m wondering is if I’m going to notice huge differences in the usability of my current lenses or is it going to be just somewhat better? One of my favourite outdoor lenses, even though it’s heavy is the Minolta 28-135. I find it narrower than the kits 18-55 which has lacklustre colour. Wondering if it’s going to feel much wider

FF light performance is better. Matters when depending on available light.
Resolution can be 20mp up to 61mp. For the latter your glass has to be able to resolve it for it to be any use.
