With retuned T* coatings to suit, the resultant SF+ would have both higher light transmission AND a more balanced transmission curve with more colourful, more vibrant blues and reds, AND a more neutral colour rendition - finally getting rid of that 'green ham' colour cast ...... of course then they would have to fleece their customers less, but the SF has been out for quite a while now - surely they have made some cost saving productivity increases that they could share with the customer."True. But if they did they would be cannibalizing the sale of their own HT model. If you can get it all on the SF why buy the HT. They have to differentiate their products in some areas.The HT has the low light market and the SF has the big FOV market. So to get it all you have to buy both.</blockquote>
