Canon Powershot G1X and screwthread

[Lauvau]

<p>Hi,<br />I just bought a Canon Powerhsot G1X, which is a very good camera!<br />I will wish to protect the lens with a neutral filter, the lens has a screwthread for filters, but I found nowhere the exact diameter (approx. 45mm I think). Someone of you knows precisly?<br>

Thank you for your help.</p>

<p>I believe you need to buy the Canon FA-DC58C filter adapter. Then you can buy 58mm filters.</p>

<p>Thank you for your response. This is exactly what I need to buy. It's a shame to dont be able to use the thread screw of the lens directly.</p>

<p>I think 46mm is the more likely 'standard' thread diameter. The bigger the filter the more expensive they are so I would avoid Rob's suggestion if that is a consideration to you. I have 46mm filters on one of my cameras. If you have problems locally, once you know the correct thread, I suggest <a href="http://www.srb-griturn.com">www.srb-griturn.com</a> as specialist suppliers. Quite apart from having a 58mm filter on a camera designed to take 46mm filters, not really appropriate.</p>

<p>JC,<br>

The only way to mount filters on the G1X is to use an adapter. You cannot screw them in. The OP has confused ridges with threads. The ridges are there to secure the lens cap and cannot be used for filters.</p>

<p>The adapter is a bayonet-mount and attaches to the outside of the lens.</p>

<p>At this point there are no other adapters other than the one by Canon made for the G1X. In the future LensMateOnline may provide a less expensive/better one, but that is only a rumor. Were they to produce an adapter, it too would require 58mm filters.</p>

<p>I think Rob is right, the screwthread of the G1X is not compatible with standard diameters of filter, that is voluntary in fact ... and that's a shame!</p>

<p>The adapter is the way to go; mine is on order. I'd like to add something about the G1X that may save others some headaches. When I got mine, the "flash control" menu item was greyed out, and the "flash" icon on the four way controller did not respond. I called tech service (wonderful, quick response and solved the problem in a couple of minutes) and the problem turned out to be the small plastic hot shoe cover. There are two small spring loaded buttons at the front of the hotshoe, their purpose being to disable the flash control in the camera menu when an external flash unit is mounted. The little plastic hot shoe cover that came with the camera was pressing on these buttons so the camera thought there was an external flash mounted and greyed out the menu item. Removing the plastic hot shoe cover released the little springs and restored flash control in the menu.</p>

<p>So if "flash control" is greyed out in your menu, just remove the plastic hot shoe cover. I replaced mine with a different one that doesn't engage the springs.</p>

<p>Thank you for your experience.<br>

I just get my first prints at the lab - 20x24in. c-print - they are superb !</p>

<p>Thank you Rob for pointing out my error since I don't know the camera but my personal solution to a similar situation with my Nikon 5700 was to get myself a step-up ring to the next 'standard' size. The threads of the step-up ring needed turning down a touch to fit the ridge on the Nikon's lens and I was able to fit the 46mm filters/close-up lens as mentioned above. <br>

I repeat fitting a 58mm filter to a 45mm lens is ridiculous <strong>if you have the ability</strong> to do what I did*. The difference was so small that without the lathe that I used one could probably just use sandpaper or a fine file to do the job. The ring is a press fit and remained on the lens for around three or four years and continues to work AOK to this day some years later.<br>

*The only argument would be if 58 was the thread of the largest of several lens and one was ecconomising.</p>

<p>One more reason not to purchase this camera.</p>
