For $300 (I presume US$) all you'll get is a 50 f1.8 or 1.4. That'll give you speed in a "80 mm" lens. For more reach, perhaps the 100 f2 lens would be a choice but it'll cost more money.
Yes, US currency. I've looked at the 100mm f/2.0 but have decided against that. I could use my 70-200mm on manual focus to obtain 100mm. It wouldn't be as fast but it also wouldn't be overkill.
You refer to yourself as JABACO sports so I now have make some mean observations. If you were an amateur just looking to take pictures of your kids shooting hoops, then you use what you can afford and gain experience as time and effort goes on.
But if you are working professionally and selling this stuff I think that you need to step back. Snapshots from the baseline with a hotshoe flash indicate to me that you really don't a) know what you are doing and b) don't know what anyone ELSE is doing either.
I wouldn't classify me as a professional nor an amatuer. In the past two years, with hundreds of happy Mom, Pops and Grand Parents, I've been shooting outside sporting events and this month began to shoot basketball. Hence, the advice I'm asking.
I never nor do I ever want to photograph weddings and such. Not my style. Maybe I don't want to deal with brides, brides mother or future mom-in-laws. Or I just hate wearing a suit and looking suitable, if you will.
Once in awhile a kid will say, "Well I'm just starting out and I don't have this equipment." And I'll say, "Do your sister's wedding. Help a pro do theirs. But don't pass yourself off as a pro. If you can't do all of this walk away until you can."
Get the gear, get the experience and THEN sell your product.
I have the gear and the experience for what I do. I'm now in a new area which is why I've asked for others to offer their opinion, and only their opinion of what I have asked.
While I respect your thoughts, I've used this forum for my extended education in a field that is highly technical.
I am a tennis instructor and I run into plenty of wanna be pro's. I enjoy them and even try to help them when I can. They, at least for a short time, will bring more players into the game. Well if they flame out, I have more potential students than before. If they maintain, then more power to them.
Some think they know it all, All think they know some - I think I know all of it some of the time and sometimes all the time.
