Originally posted by Christine Tham I love the pictures you have taken with the kit zoom. I don't like zooms, so normally I would recommend the 55 but the shots you have taken show that a zoom can be very useful on a bushwalk or a climb.
But just to make the decision harder for you, here is an image taken on the FE55 with continuous AF. Sony has really improved the continuous AF mode on the A7r - it does real time object recognition and tracking using CDAF - it draws a rectangle around the object it is tracking in real time and it can actually vary the size of the rectangle as the object moves around:
Thanks. Yes, I definitely need an AF zoom for climbing and I often don't have time to change lenses while on the move bushwalking either. So really I've got to decide which one to get. The options I can think of so far:
- Just keep the kit lens. It is ok, but I feel there is something special missing from its shots. But then, I've got/will have good primes for those special more planned shots too.
- Get the FE24-70. Expensive. And would pretty much blow my camera budget for a fair while to come. But, the saying "do it once, do it right" comes to mind.
- Get an LA-EA4 + Tamron 28-75. Bang for your buck option and pretty compact and light for f2.8. I was very happy with my 17-50 on pentax.
- Other??? Canon 24-70 f4L + metabones AF adapter? Gets heavier and probably end up the same sort of price as the FE option. Plus AF isn't that great. Something manual like the C/Y 35-70 gets great reviews and I think a manual zoom would be ok for walking, but not for climbing. And it doesn't go as wide. But then I could keep the kit just for climbing... and so my thought process goes round in circles.
With regards to the AF-C. Yes, that's what I was using to get those climbing shots. Keeper ratio was pretty good. I'd say around 75 - 80%. However, it was hard too because I had the rope coming up from the climber moving around as well. I had face recognition turned on too, but I'm not sure how much it was doing since the climber often wasn't actually looking up. It would sometimes get a bit lost, but if I just refocused it would usually find the person again and then stay on them.
