Tamron SP AF 28-75mm f/2.8 XR Di for Canon

09/12/2005 11:39:58 AM · #1

Last week I took the plunge and bought a 20D. The problem is that I wear glasses. With my glasses on I can not see everything in the viewfinder, because of the increased distance between my eye and the viewfinder. With them off the dioptric adjustment falls just short of providing a clear image. Canon offers an eyepiece extender that reduces viewfinder magnification by 30%. Would this allow me to see everything with my glasses on, or am I better off trying to figure out what dioptric adjustment lens I need so I can see clearly without my glasses?

I am not certain, but I think you would have the same issue with the extender. The eyecup is the same size, it just sticks out about 1/2 inch.

It makes looking through the viewfinder more comfortable, but I stopped using mine because I disliked the reduced view. Not bad for landscapes and walking around, but it was killing me on macro stuff or anything that required critical focus.

Is the D20 markedly different than the 300D? I have worn glasses nearly all my life and have had three Canon cameras none of which presented any problem for me being able to see the full frame.

Binoculars, on the other hand, drive me nuts.

I wear glasses and this is not a problem for me. I wonder why it is for you? Not doubting that it is, just wondering what the difference is.

Hi-ho,

I wear glasses as well, and although I don't find it annoying, I can't see all the view finder with my glasses on, unless I 'mush' my face/glasses into the back of the camera..

I suspect it depends on the shape of your face, size of your nose, 'depth' of your eye (how far back from the glasses they are), shape of the glasses etc..

I'm due for a new glasses prescription in a few months, so I was going to get slightly smaller lenses, with a closer fit to my face so I can get up close and personal to the viewfinder without too much mushing...

Cheers, Me.

I had great luck in adapting a lens from an old pair of glasses to be a custom eyecup/diopter for my D70. I obtained a spare viewfinder cover, got some glue and tape, and behold:

my 300D has a focus dial for the viewfinder, doesn't the 20D?

Yeah, but it only corrects for near/far vision issues, and only within a limited range of those. Diopter adjustments can't correct for astigmatism or other such defects either. In my case, I COULD adjust the diopter not to need my glasses, but then I'd have to take my glasses off every time I want to look through the viewfinder and that's extremely inconvenient. So I shoot with my glasses on.

Contact Canon. They have different ajustable replacement diopters for some of thier cameras.

I had the same problem when I got my N60 film body a few years back. I was able to get a diopter correction from Nikon direct that worked perfect.

Interesting thing is I don't have the same problem with the D70 that I did with my N60. If you have the money, I'd suggest trying a couple of different solutions. (The eye cup, a different diopter etc. Figure out which one gives you the most versitility.

Because I wear contacts my diopter correction on the D70 is a smidge off when I wear my glasses. So I just tend to trust the AF when I have to shoot sans contacts. It's a hassle to try and switch the correction back and forth.

iirc the add-onviewfinder gives you a much wider range of diopter adjustments, so will work for almost any glasses-wearer

Diopters, by definition, ONLY correct for near/far vision defects. As far as I know, there are no off-the-shelf solutions for astigmatism and such. I'm sure it's possible to get custom-ground replacement glass with such correction built in (I don't honestly know) but I'm not aware that Canon (or anyone) has such custom-correction viewfinder glass in stock.

I have the same problem with my 10D, and it is my single biggest problem with the camera. I have the magnifier, but the image becomes so small that it is hard that it is difficult to use. As someone already mentioned, the best solution so far is to MASH my face against the back of the camera. It's not comfortable and I get tired of having to wipe the LCD on the back of the camera, but it's the only thing that has worked.

I really miss my old Nikon F4hp, that viewfinder was amazing!

Thanks for the input. I took it out the other day and it didn't seem to bother me as much. I guess I'll wait and see how I feel about it in a week or so.

Sounds like you're wanting the Canon EP-EX15 Eyepiece extender :o) I've got one myself, and it makes using a 20D while wearing glasses that much easier...

I suggest laser surgery!

Seriously it stops all these problems and means you can see in the rain or when you open the dishwasher or oven!!!

After 40 years of wearing glasses I am discovering a whole new world of sharpness and colour. (hasn't improved my photography talent however!)
