CAn you use refresh optive with soft lens....?

Yes, you can.....I got mine from my Optometrist just over the weekend and he said it is safe to use with contact lenses (I wear soft lenses, too) or bare eyed.

The more I read about it online, the more it sounds like it's the iA 'algorithm' that is slightly flawed. Many blogs/websites all sight setting adjustments as the easy fix. Not so cool for someone like me that was hoping to rely on the iA for my day-to-day pics, but I guess it's a learning opportunity! Good luck yourself, I will say that other than this one issue I love every aspect of the camera. Will play with settings tonight to see if I can crack it.. ~Rich

I personally have no experience with soft lenses and the remover. I use gas permeable lens and the remover inserter works fine. Because soft contact lenses are so fragile the inserter remover might damage them. The short time I used soft contacts I simply used my fingers to remove them. You can try it because the cost is relatively low, but remember that the soft contacts are fragile and can easily be damaged. I hope this answer helps.

From my experience using this adapter with an FD 50mm f1.4, the corrective lens causes a soft edge, or "bloom" effect at F-stops faster than around f2.8, creating an unusable image. Im not sure how the difference in focal length will affect it though.

You can, but have to set the polarizer after focusing. Typically not a problem for distant / landscape shots as the ring is mostly around infinity focus.

Not for me. I tried to use old (1970's) Asahi/Takumar lenses on a Nikon camera and unless it is a sunny day, or inside auxiliary lighting is very good, I cannot open the aperture for enough light even manually.

Yes, but apply the cleaning solution to the cloth you're using instead of directly to the lens.

I don't see why the 70-200 would not work...it's very adjustable. I don't do too much follow focus with it, it's ok, but not the best for that, but none of these type of focus design work all that well for me.

No focus peaking -- many have requested that -- and there are rumblings that it will be in a firmware update, but nothing solid that I know about.

Yes, I've used them with both. Focus is a little bit slower and most times I had to manually adjust also because it didn't focus exactly where I wanted it to. So when I use these, I use DMF as my focus setting.

Absolutely. This is how I use it although with different primes - 2.0 and 1.2. Regardless, you'll find yourself seeing through a much nicer viewfinder which I find useful even if I'm auto focusing or not. Here's how I see it: this focusing screen should have come standard with my body. It's that good.

Yes, you can change it as long as it the same lens size. I change mine to an auto darkening lens.

In general, no. Your eyes are only capable of picking up a certain rate of frames and refresh time. While it is less than what you are coming from, It would take a very detailed eye to pick up any change. I use mine for sports and video games, both requiring fast refresh and no ghosting.

Friend, I checked and my lens is the macro, and maybe my reference maybe wont work

Tamron told me there is a firmware update that must be installed to work well with the 70D. It was just developed about two months ago. Any lenses made before then will need the update installed. I just sent me lens to Tamron this week for them to update it. Up to this point I could only take a handful of pictures at a time before it brought up an error message telling me to clean the contacts on the lens or camera (can't remember the exact wording). I'm hoping all is well when I get the lens back this week.

yes, check your settings (resolution and stability and auto focus ) adjust accordingly and snap away
