A 2.8 lens, while nice, is not necessary for outdoor motocross. And you will find a fixed focal length to be quite restrictive. My recommendation - a Nikon D5600 with the AF-P DX 70-300 zoom. You should be able to get this kit for less than $1000. For shooting action it will have a much better autofocus system than the A6000, and the zoom will allow much more flexibility with framing your shots. The lens is slow (it will be f/4.5 at 70mm and f/6.3 at 300) but outdoors that will mostly be ok. For a few hundred extra there...

I have the a6000 and you can do some nice stuff with the 55-200 it comes with. But you need to anticipate the shot. Great little camera! I also use it to shoot skateboarding and it is perfect for upclose action shots.

One lens only? I'd second that.

70-200MM 2.8 fo sho

2.8 is plenty fast enough. Any wider of an aperture than that, and you'll find that DOF is too shallow to get the whole bike/rider in focus. I'll usually stop down to ~3.2 Then 90mm is pretty short for moto, and I think you'll really struggle with it, as your only lens. I use a 200mm 2.8 prime (I shoot Canon, FF sensor) 99% of the time. Your best option is going with something like the Sigma 70-200 2.8, but I'm guessing that is out of your budget? So, you're probably looking at going with the Sony 18-135mm...but the IQ...

I recommended he goes with a 2.8 mainly because Sigma doesn't make a 70-200 f4. Also, because having a 2.8 is going to be more versatile than a 4. All of these lenses are out of his price range (assuming he wants something priced similarly to the Sigma 60mm he listed), so I listed the Sigma 70-200 because it is the ideal focal length/aperture or moto, and because it (a used one) is the most reasonably priced 70-200 option out there (for Sony mount)...gives him an idea of what he'll need to save for. Now, personally, I love a shallow...

Can you share "why" you would suggest he spend the extra money on an f2.8? (I know why I did but I'd like to hear why you guys think he should.) I say this because for the type of shooting he described, a medium to high end f4.0 lens will actually work quite well due to lighting and depth of field forgiveness. For example, when I shoot action, I'm usually shooting at f5.6 or smaller (aka a bigger number) and typically around 600-2000 Shutter depending on if the rider is coming, going or moving across and if I want motion...

It doesnt matter how good of a racer Ronnie MacAlbertson is. Or if he's faster than the top riders from many other countries. Mx des nations shouldn't allow a clown show. They could then take a national b-team from every country, and make them like funny teams, in the name of charity. Puerto Rican team, yeah right, that whole thing is a joke. That said, if Albertson will race I don't believe for a second that he would do it as Ronnie Mac.

I'm all for having fun and making a joke out of literally any event on earth except the MXdN. Ronnie Mac is perfect for the US Nationals, US Supercross, Red Bull Straight Rhythm and Monster Cup events. Just not the most historic event in our sport that is seldom on US soil.

Sure looked like Barcia flipped off Webb on the way by...
