Sony RX100 mkii, lens noise
342613
Bought this for my Sony RX100 mkii. Both the zoom and shotgun feature work well, but the camera still transmits mechanical lens noise to the mic when zooming. This is an issue with the factory mic, when the lens is zoomed in and out, the camera pics up the mechanical audio from the lens, the ECMGZ1M still suffers from the same issue. There is no damper between the mic and the camera body, its probably the vibration that is being picked up. Mic audio is excellent, audio isolation is fantastic, wind noise is non existent, the size is acceptable on the RX (it about as long as the camera), and the mic is light so its easy to carry. Build quality appears to be good, its an all plastic build. It can be a little difficult getting the mic into the hotshoe on the camera, but that may just require some getting used to. Overall not a bad product, itd be a 5 star product if there was a way to prevent lens noise on the RX100 mkii using this mic.

DUST ON THE SENSOR!!

An otherwise good camera ruined by a very serious dust problem.  The only way to clean the sensor is to take the camera apart.  Just terrible.

The laptop is mostly solid, especially at the price, except for the incessant fan noise.  I really don't know how Sony could have overlooked this issue.

The lens stopped working. It seems the motor inside is seized as it makes a grinding noise when trying to use it. I am not sure what my options are. I tried to return it and I was told I can not as it is been over a month since I bought it.

This filter looks good and I have not experienced a shift in color. However, the build worries me. The lens is loose in the ring housing, so there is a slight rattle when shaken. The lens turns a bit within the ring when cleaning. I had hoped for better, coming from a reputable manufacturer like Tiffen. Otherwise, the filter seems fine. I will updated this review if I have anything more to add as I use it more.

I'm pretty happy with the camera but still can't understand how sony up to this point doesn't include image Stabilization, really lame of them, and the mode in high sensibility for low lights pictures it's not that good u can actually see noise on the pictures, also ehn using the flash a lot of pics turn out wiht the red eyes, even though the anti-red eye is on :/

I have software issues with lens. The image stabilizer is doesn't work properly. I bought it as a gift when I had the money to and now  as I have returned home to give it as a gift I realize that this is a faulty lens. I had the outer components fitted for manual focus ($300) and now that money's down the drain as well. I need this fixed as soon as possible as it's a Christmas gift. Thank you.

When I received this lens I took several test shots at F/2.8 on up to f/16 to test for sharpness (tripod mounted) at a distance of 5-6 feet.  My lens was suprisingly soft at f/2.8 to f/5.6 or so, even compared to other telephoto lenses (e.g., Nikon 70-300mm)at comparable apertures.  I called Sigma technical support but they were not much help so I sent it back.  I was really hoping I would like this lens since it is much lighter than my (full frame) 70-200 f/2.8.  I received a full refund from Amazon so at least the experience did not cost me any $$.

It's a great lens with one glaring problem, when it is on my phone the sound quality is reduced to basically zero. I wanted to use this lens for live streaming but unfortunately the sound quality made that impossible. I use an IPhone 6S plus.

Good lense for the price, noisy when it tries to autofocus. i should have gone with newer version of this lense

This will be my 3rd Sigma filter.  The second filter was on a 55-200mm Nikor lens until this afternoon when my wife dropped her camera.  From the scratches on the lens cap, I'm guessing the camera landed lens cap first and that shattered the Sigma filter.  However, the filter did its job and protected the glass on the lens.  So instead of spending $200 to buy a new zoom lens, I'm spending $20 for a new filter.

I bought this camera to replace my 3 years old Panasonic GF1, a small camera that travelled with me everywhere never letting me down.

The RX1 looks and feel like the "old" Leica MP, beautifully built, incredibly lens, i own few digital SLR but this one will beat all on them in term of quality, but one important aspect let me down.

The autofocus is painfully slow, especially in low light, it takes few second to focus, honestly i wonder how this was not been noticed by anyone at Sony.

I will return the camera waiting for a fix or possibly the next RX1.

First it unfortunately could not eliminate the focus noise from my USM lens.  It didn't claim to, but I was hopeful since it claimed to "mechanical noise of cameras".  It did not;  Im going to have to go off-camera microphone for that.  I was using a 28-70 2.8 L. I didn't test with the new STM lenses.
My only other complaint is that this is called an interview mic and is configured for on-camera use.
This does NOT work well.
At 6-8 feet or so the audio sounds sort of muffled and sort of underwater.  It's not horrible, but its not good either.
The problem is that the mic needs to be a lot closer to the speaker to get good results; a foot or so.
To do this youll need a 3.5 extension cable, and a hot-shoe to microphone stand adapter, and a stand.
In short this mic is pretty much useless on-camera as shown, but at the price, its not a bad mic at all.
Im using this with a Canon D70.

Great image, easy set up but sound is totally wiped out by wind noise when mounted on a motorcycle or on a crash helmet.

I recently purchased the Zr100...I'm pretty camera literate and knew Canon to be a good brand. Brought the camera home and was playing with...when I was watching what I had recorded I noticed a "white noise" in the background...even when people were talking. The motor/fan on this camera is so loud that it really distorts and videos you take...it sounds like an old reel to reel is running 5 feet away. I called Canon about it and they suggested that I play background sound while recording to drown out the sound of the motor...well that doesn't work for video taping school plays etc...I'm returning this camera...hopefully not all MiniDVs have this problem.

When I first purchased this lens, it would make a lot of clicking noises (hunting) and would not take pictures.

I sent it in for repair and it seems to work better.

Now after a few months, the lens creeps very fast when the camera is held in a downward position.

Going back for repairs again.

On my new Sony A7R III, the back side of the lens mount on this adapter reflected a bright ring onto the sensor, causing a bright ring of flare that cut through the corners of full frame images. It was fine on my APS-C sensor camera, an a6300.
The light reflected was what was coming through the lens. The adapter is very well made and I was otherwise happy with it, but very disappointing to find that flare ring caused by it!
I painted the back of the lens mount flat black, and the problem is fixed. Oddly , although the lenses' mounts are themselves bright chrome, I can see no evidence that they are causing a similar flare. That's something else to figure out.
