Can you pull the lens or turn the zoom ring at all, when yours is tight, or do you find it to be truly locked?


Kim,

The friction ring won't provide a true "lock", just progressively more or less resistance to turning the zoom ring. Assuming Sony has used a similar mechanism as Canon has in the EF 100-400 II, the detents you notice at the ends of the range of the friction ring are probably spring clips that simply hold the friction ring at the ends and do not provide actual resistance. I haven't seen a tear down of the Sony 100-400 yet, but hopefully they aren't using ball bearings and friction pads that can wear down over time like the old Canon 100-400 did. Regardless, I think that with a lens that is still relatively new and under warranty, I'd just send it in for service.

Yup, just hoping for an adjustment. Hate thinking about it being in some repair shop for an extended time for something so simple.

Definitely works better with the A9. Here is a LIF (leaf in flight) example, full size followed by crop.
OOC, no sharpening applied.

Hello, When set to Tight my lens stays in place. I do hear and feel a click when setting to the Tight position. I am still able to turn the zoom ring with some resistance of course but the lens does not creep forward on its own in the Tight position ( at least on my copy). Don't think I want to try to force it otherwise.

When I walk with mine, set to full tight, the lens still gradually extends - over time/with steps, not quickly, and I haven't let it go to see if it keeps extending past an inch.

I will probably send it in for repair, but I am a little concerned about timing and whether something might go wrong while it is being repaired.
A couple of years ago I accidentally dipped a lens in a stream (don't ask). After a thorough drying, the electronics worked perfectly, but there were water drop stains on the inside of the front element. When I sent it in for repair, Sony said they could not fix it (though they did fix the camera body that DID have fried electronics from the dip, for a reasonable charge). After a couple of years sitting on my shelf, I followed a YouTube video about how to disassemble the lens, took it apart and cleaned the front element. Works perfectly now. Not sure why Sony could not do that, since it would only have been an hour or so of labor.

Hiking up the stream at Zion and slipped on a rock. NEX-7 with 18-200 lens went under briefly. Camera stopped functioning, but Sony repaired it with a reasonable charge. Lens was still working, but had water drop stains on inside of lens.
I got slightly wet, but dried out with no repair required.

Drones get confused when flown close over water and will dive in. Not good.

The more drones find a watery grave the better.

Looks like a lot of noise reduction. Do you have any photos at lower ISO w/o as much noise reduction? The lens + extender looks promising.
