2. include (by design) a flatterner and
3. are faster (or could be used stopped down for even better IQ).

Unless of course, telescope it must be. In which case: Back to normal programming -

Though if I didn't have the 120 version of this I would not dismiss it, one of the best reviews around for scopes are the Esprit triplets not on your list

I think that unlike us conned in the UK YOU get the FREE field Flatterer, we have to pay for it

Thanks for that. These ads though are worded so vaguely I always feel they are lying.

3 ED elements but not named. OK one is FPL53 what are the others? F5 is tough for FPL53 so it would need something else.
No mention of the corrected imaging circle so I assume its too small otherwise they would tout it.

Crass sort of marketing really where they try to spin an image of perfection without saying a lot about the actual specs. I don't know about you but I won't make a decision based on sketchy data.
