Champion, funny thing these forums, you see and hear a lot about LBA, and you see some people with amazing lens collections. IE This thread, pure lens porn!!! Young views should look away at this point.....
https://www.pentaxforums.com/forums/post-your-photos/76488-lens-buying-addict...ages-lens.html God, Thats an amazing collection, I've got half a chubby just looking at it again......
But don't let it get you down, you seriously don't need a million lenses, you have a great start with what you have, and you will learn a massive amount due to the fact that "all Digital Photos are FREE" . You should have tried learning 30yrs ago, when cameras, in relationship to todays cameras where almost more expensive, then every roll of film cost more, then developing, then, when you liked a pic, it cost more to get an enlargement. I personally only had a 35-70 and a 50mm for the first 4 yrs of having a 35mm SLR, and another 10 before I got a FA* lens, most of the big collections you see here are built up over 10 - 20 years. I myself am about to sell nearly all my lenses because honestly I actually use just my favourites, and the rest are collecting dust (so to speak)
As other have said, by the time you sell your gear, and then buy new stuff, you'll probably only replace what you have with lesser gear, and not be any better off financally, then you'll just get frustrated with it, and stop. Digital is a Golden Egg, Remember you can take 1000 photos a day and its FREE!!!!!!!!!!!!!!!!
As to old lenses, you can really buy absolute bargins, for very small outlay. Don't worry about manual focus, Manual, is actually fantastic for creative control in your pictures. And honestly, you don't really hit "Your Style" till you've had a bit of a play for a while. What some may praise, may mean nothing to you, and what you treasure may mean nothing to others, who cares, whats important, is why you want to take photos and what you like to create.
