I have never had any major problems with any pentax film camera finders, even the ones with the least eyepoint. The MX finder is glorious and it does take a little more care to get a good look but I like that type of design over a tiny finder with high eyepoint I dont want or need. To each his own I guess. This accessory magnifier looks interesting but I am skeptical it would be as good as an internal eyepiece designed to give higher magnification in the first place. jco

I've yet to see a finder on 35mm over .85x magnification that is easy to see all of the viewfinder area (The MX was particularly bad for that) even if you don't wear glasses. While the MX is easy to focus, it's rather hard to frame images on. Note that DX format DSLR finders already run much higher magnifications (.95x is pretty much standard for mid/high end bodies and low-end bodies are settling on .8-.85x, which is 10-20% more than the film bodies). Apart from the ME's and MX, with their .95x(ME) and .97x(MX) finders and horridly short eyepoints, Pentax 35mm finders are typically in the .7-.8x range, with 90-92% coverage. The DSLR's are either .95x or .85x with 95% coverage. So you're getting more coverage at higher magnifications, although the effective magnification is slightly lower. You could give up coverage for more magnification, but that would cause more problems these days, as unlike the film era (which crops down both edges on a print unless you do rebates), you typically use the full frame of the uncropped digital image on at least one dimension. -Adam J.
