So as of today I have started having an issue or possibly 2 issues with my Pentax K-70.
My camera is under warranty and I want to know if I should send it back for repair...... unless someone here can tell me more information on the issue.
When mounting a lens onto the camera (so far I have only tried two lenses) it does not lock into position correctly.
I have tried to mount a D-FA 28-105 and also a Tamron Di SP 90 Macro lens today and once the lens is correctly turned to lock into place, it doesn't lock into place.
I correctly line up the red dots to begin with and turn it anticlockwise to lock into position and it reaches the intended position without locking - meaning I can freely turn it back clockwise again as it didn't lock.
When I place the D-FA 28-105 into place and turn on the camera, the focusing works perfectly as it is electronically controlled.
Turning my camera switch from AF to MF works completely as intended with this lens attached
When I place the Tamron Di SP 90 into place, the focusing does not work at all and I can hear the motor trying to work but nothing happens.
I can literally hear 4 quick motions of the motor (almost like a tapping) and then a winding of the motor with no results at all.
I can manually focus but the auto focus does not work.
No difference weather I have the lens itself switched to manual or auto (I can pull the focusing ring back for manual or forward for auto) and no difference is notable weather I have switched to AF or MF on the camera in this case either..
When I turn the D-FA 28-105 lens back and forth a few times to attempt to lock it into place, it eventually does lock.
I then un-mount the lens and try again but it doesn't seem to lock without turning it back and forth 10 or so times.
This does not happen with the Tamron lens.
----UPDATE---
I just tried several other lenses (Pentax DA 50 1.8, Pentax Pentax DA* 55, Pentax DA 18-55 Kit lens and Pentax DA 40 1.28 XS)
Once I put the 40mm lens into place, the lens being so thin, I gave it a little pull upwards and heard the locking mechanism activate and locked into place.
I then tried the Tamron lens once again and it worked fine and locked straight away.
Evan though the camera seems to be now working fine, this tells me it is not the last I have seen of the issue.
Could there be some dirt or residue in the mount or lock itself??
Visually, I can see nothing wrong or dirty with the mount, in or around it.
Another thing to note is the environmental parameters, as the manual tells me that the maximum operating temperature is 104 °F (40 °C) with humidity at 0 - 85% (non-condensing), 0 - 80% (non-condensing)
Today's temperature hit 39.8 °C at 4pm with 11% humidity where I live in Australia.
I didn't even turn on the camera until around 6 or 6:30pm when the temp was 31.8 °C with humidity at 19%
What do people recommend ?? Is this worthy of sending the camera back for repair ?
My K-70 camera is less than 6 months old and has just over 25,000 activation's (a quarter of its shutter life expectancy)
Could this be related to the weather?
Any and all help is appreciated and thank you for your time in advance.
