Does the mask have a Purge valve also? Does the lens curv across the front &amp; ovr to the side of your eyes so frame doesn't block peripheral vision?

It does not have a purge valve, and the frame does somewhat curve around, I have had no trouble seeing all I needed to see.

I've been using the 14-24mm f2.8 for a year now. Tack sharp! No lens creep. I was worried about no filters to protect glass also. Built in lens hood protects front element well enough. Lens cap fits OVER hood when not in use. I am comfortable with that. No VR doesn't seem to be an issue, as a lot of light comes through the glass and allows higher shutter speeds I feel. I generally shoot with a standard ISO of 400 to kick it up the speed a bit. Great lens. I also use the 24-70mm and 70-200mm lenses, both at f2.8 as well. Throw any pic from these three lenses on you monitor and you could cut yourself on the sharpness. LOL. I've been using the 14-24mm f2.8 for a year now. Tack sharp! No lens creep.

Look for a mask respirator. The type that blocks dust should do the trick.safety Glasses for eye protect.

It is common for many extreme wide angle and fisheye lenses to eliminate the front filter thread, since the filter would have to be very large to avoid vignetting. The Panasonic 7-14mm has an integral "petal" style hood that provides reasonable protection from accidental impact to the front element. As far as dust, dirt, water are concerned, you just have to be careful. I haven't had any problem yet.Also, if you actually want to use filters, there is a gel filter recess on the rear of the lens.In summary, I wouldn't let the lack of a protective filter prevent you from enjoying this excellent lens!

There is a lock somewhere outside the lens near the body. This might prevent you from changing the focal length.

Not absolutely sure, but on this lens there are two VR setting, besides "off"! One called "normal" which is for normal hand held use... the other is called "active" which is supposed to work well for taking shots from a moving vehicle. Initially I thought it was for sports photography... duh!

Dear Ed:This is a very nice, small unit. It does not have an opening for a full sized shop vac, but it does have a 1 3/4 inch opening on the left side. I have found that it just doesn't give out that much dust. I have not ever found it necessary to wear a mask. After any work, a quick pass with my small shop vac picks up all the let over debris. Best,Dan

It might actually be better for people with lower bridges. My bridge is a little high and it holds the mask slightly off my face creating the gap that lets light in. The further away from the expected average you are, the less perfectly a contoured mask is going to fit you. It still does a good job though. Unless there's a light shining up into the gap, it isn't very noticeable when I'm looking straight ahead.

Prescription glasses? I wear -8.5 correction (very nearsighted). The glasses are those small "reading glasses" style which are tough with this style of mask. To make the mask work properly you have to carefully fit the mask then adjust the glasses along the internal mask. The trick is to get the glasses to sit on the internal mask while adjusting them outside on your ears. Doing so I was able to get into an eighteen inch high crawlspace then laying on my side remove a dead groundhog that was a week and half decayed. I had no trouble with seal or seeing. I have to emphasize - you have to work with the internal mask and your glasses to make this function. It's not a "plug and play" operation. So, yes you can use this mask with prescription glasses but it's not a trivial process. When you get it right the mask works properly and you can see. No fogging either.

You can loosen the goggles to make them less "suctiony" but the plastic seal may still be more suction than you want. It would definitely be worth a try. The mask is easy to adjust.

It doesn't do either one. All it did for me was make both lenses blurry and I couldn't remove the cleaner. I had to buy a new pair of glasses. Don't buy it! That's my advice to you.

your looking for a new mask system I take it? this mask in full is much heavier than the Fx from resmed, this item as I am sure your aware will not fit an FX mask, just stating for clarity. This mask has good comfort but it is much heavier overall. This mask system also has a forhead support pad that the FX does not, so wearing glasses while wearing this mask is not an option. any other questions I will be happy to assist.

Of course, no bbs can fit through in between the lens the the frame of the helmet. Like all helmets. Good thing is that the lens rarely fogs up after a few hours, and if it does you can just take it off for a minute and should be back to clear. The lens is sturdy and hard I guess "Reinforced plastic". Basically best airsoft mask you can get for this price, mp3 attachments are not good for this.

Interesting that you asked this question as I am pondering this myself though with the haze filter. Different schools of thought from using as "protection of camera lens" to cutting glare to those who don't use them at all. This filter is on at all times during the day unless shooting in very low light. My haze filter not so sure about.

I have a small nose and the nosepiece acted like a window for light. The mask was completely ineffective at blocking light for me. However, I had no problem returning it. Little noses, this may not be for you.

Nikolai, This is a good designed mask for any dusty job. The reason I spend more for this design is because of the front vent that directs the exhaled breath away from fogging up my eye glasses.

I am so accustomed to wearing a snorkel, I haven't noticed that it impairs vision at all. I wear goggles every swim so, I would say its safe to wear a mask.
