A99 and Sony 18-135mm Lens

Coming from the NEX 5N and NEX7, I am very new to the A99.

On the NEX cameras, in order to see the red effect of DMF, you had to hold the shutter half way down while turning the focus ring.

On the A99, I get the same effect without having to hold the shutter half way. I just point the camera at the subject, turn the focus ring for maximum sharp focus (either in AF or MF mode) then press the shutter button.

Is this what other users are finding ?

Even the NEX cameras were configurable this way I believe.

Also, your 18-135mm lens is a DT (crop) lens - you *do* know that, right?

I'd strongly recommend you immediately check the manual that came with the lens. As this lens is SAM it may not be compatible with DMF and you could be stripping the gears by turning the focus ring without putting it into manual focus mode.

My A99 came with an official Sony kit lens - the 28-75mm SAM lens. It is incompatible with DMF, as stated in the lens manual.

OK Thanks for those tips...I will check it out further.

My confusion stems from the fact that in the A99 User Manual on page 105 Step 2 says to press the shutter button halfway down. Yet it appears I see the same effect without having to press the shutter.

Oh. You mean the peaking effect. Yes, the manual is wrong. The peaking will show constantly if you have the camera in DMF mode with peaking turned on (there is a choice of 3 colours, and I use yellow), but my non-DMF lens does not show peaking except in manual mode.

The 18-135 lens is unique among the SAM lenses, in that it is the only one that allows full-time manual focus (like you get with the SSM lenses).

Thus, you don't really need to have the camera set to "DMF" mode to get DMF when using this lens.  Even in the "normal" AF modes (AF-S, AF-C), you can always turn the manual focus ring on the lens to fine-tune your focus.
