Pros: Can use the viewfinder without glasses
Cons: Falls off easily. Not available for stronger corrections.

I had one of these on my MX but it worked its way off while I was walking around with the camera hanging from a strap around my neck and I lost it. Either keep your camera in its bag, or remove it if you are going to be walking around with the camera hanging around your neck or hanging from your shoulder.

Pros: Great glass- Fits K3 DSLR- Good price
Cons: No ridge for eyecup Buy from Japan through AMAZON

I am able to use my manual lenses again. The difference in clarity of what you see is worth the price. I am wearing my corrective eyeglasses. (difficult for some people while using the diopter). I can now set and forget the diopter adjustment on the K3.

Prior to getting the +2 diopter my images were dreadful. I resurrected my K 200mm f4 and was able to get some real quality images. Now the pictures match what i see in the viewfinder in a good way.

Unfortunately, RICOH/PENTAX does not carry these items. AMAZON (cheapest I found) and E BAY about 30% more. Both Sources from the far east. Longer wait times prevail.

Your eyeglass prescription indicates what diopter to get. If you need help, check with your optometrist.

Pros: correct accurately for my eyesite
Cons: lack of rubber eyecup to filter out sunlight

really i would give it a 10 but the lack of an eyecup is a bit of a pain, but more than offset by the ability to not use my glasses (i only need them for reading so in my case it meant pulling them out to shoot and then putting them away). I have the largest +3 so i am now good combined with the built in to about +5
if you wear glasses for reading they can't be beat.
Easy to get too I just called Pentax Canada parts dept placed an order over the phone and had it a couple of days later
You can only get the newer series now (for the apsc VF) unfortunately i haven't found the old series for my manual focus cameras

Pros: Absolutely makes Manual Focus possible again!
Cons: None, zero, nada

I wrote about the travails of getting the SMC Lens Correction Adapter M -3 from Pentax here in the USA. In the end PentaxUSA Corporate stepped up and sent me one and its now on my camera.

I can't tell you what a positive difference this little piece of plastic makes for me!

My prescription is -3.5 in my camera eye The built-in viewfinder diopter adjustment goes from -2.5 to +1.5 on the K-x and K-r. That's just a wee bit too little for me And that does make a difference. With the information at the bottom of the viewfinder and glasses on I had a choice, I could view the image or shift and view part of the image and the data. Now that I have installed the -3 adapter and set the built-in viewfinder adjustment I can shoot without glasses for the first time since I was in high school I can get my eye right up to the cup and see the entire field of the viewfinder all at once!! I've tried a couple of MF shots and its easier, far easier, for me now too.

Have been out and about in the neighborhood today with several lenses for World Pentax Day. The new Adapter makes a difference with the AF lenses, that's for sure, but not nearly what it does with the MF lenses!

I've shot with the Quantaray 28-90 Macro with AF and that's been nice but when I switched to the SuperTak 55/1.8 and M135/3.5 - WOW! I had just about given up on manual lenses but with this adapter I can use them again! My ratio of focused to non-focused is more in line with lack of practice than blindness like it was Now all I have to do is go out and shoot with them more to get back into practice with MF lenses!

If you have a significant vision prescription these are an amazing addition to your camera.

I wish I knew who at PentaxUSA Corporate stepped up and had this sent to me, I'd like to thank them personally.

Pros: Clear view
Cons: None really apart from they do knock off the camera fairly easy

Great for glasses wearers, when there is not enough correction built into the camera viewfinder.

Biggest problem, but not a fault of the product, when in use is finding somewhere to put the glasses once you have taken them off, where they don't get left behind or broken but remain easily available to put back on when you finished looking through the viewfinder.

Pros: Useful if you want to take off your glasses to focus
Cons: Hard to find

These items can be hard to find but they are useful for those who wear glasses and are tired of banging the bridge of your nose when you look through a viewfinder. They come in a wide range of dioptre ranges and you should be able to find one to suit your particular needs. You should check your individual prescription with you optometrist before purchasing. There were two series of these according to Bojidar Dimtirov.

The K series features 8 lenses (-5 to + 3 dioptres) and the M series has 7 (-5 to + 2 ) all in one dioptre steps.
