Hmmm... so I'm not alone! I can certainly see the upside of the split - but was really surprised how the matt circle just "fell to hand"! So far, I think its a love affair - but perhaps in some situations, or as the eyes start to go -I will miss my split. By then, I will have probably bought more cameras than I will ever need anyway though
As to the EOS 650 - I know that screens from the T90 fit most of the EOS bodies - but I am not 100% sure of the accuracy and ease of such a mod.
Thanks for chiming in with your thoughts - it was just something that got me thinking!
