Originally posted by mtgmansf Agreed. If the 645z is to be a complete system, then an ultra-wide zoom or primes are needed, like with Fuji and Hasselblad! Fortunately for K1 shooters, the Swiss company called Irix makes two great 15mm a 11mm lenses. I have the 11mm and have seen even better reviews of the 15mm. New super telephotos, however, are still a problem...
If you can afford a super telephoto you can afford the body it goes on. People who worry about $1000 here or there aren't in the super telephoto market, unless you are talking 6.3 options. Now there are 150-600s from 3rd party manufacturers, but, the Pentax 150-450 is a pretty good lens, and no one has actually ever answered the question... 150-600 or Pentax 150-450 cropped, which is better?
"I'd buy a 600 ƒ4 for $15k right now if Pentax made one.!"
"Ya, sure you would."
The fair way to say this would be "if you have $20k to blow on a camera system Pentax will leave you short. If it's only 10k or less, Pentax will do just fine."
It never seems to occur to most, that for a guy looking for a body and 5 lenses or less, every system is a complete system, and based on the general population, that's a complete package, because it does everything they need. "Complete system" is camera person sales talk.
"You might want to buy a $10k lens sometime."
and "If your mother had wheels, she'd be a bus."
You can claim the lack of super telephoto is a disadvantage, accept for the part where a very high percentage of DSLR shooters can't afford them, making them irrelevant to 99% of these types of conversations. Most of us are limited from buying super-telephotos buy how much money is in their wallets, not by lack of availability from Pentax. Have not seen one person on the forum complaining about lack of super-telephotos, who could drop $10k on a lens. Most of it is hot air.
And it gets all kind of tiring when people go on as if those who might need a "complete system" needs to be addressed, every time someone asks a question. It's all about relevance. I know many of you are committed to the ridiculous thought patterns, but please, try and maintain some semblance of relevance. You don't get to define what is a "complete system" for anyone. There are no "more complete systems", there are complete and not complete systems. People who argue you can't get a "complete system" that ,lets their needs from Pentax are promoting ignorance. Whether or not you can get a system that is for you complete from Pentax depends entirely on your needs. The imaginary "complete system" is a figment of a few folks imaginations.
Answer the question asked, not the one you wish they'd asked. In what way is telling someone who wants camera and couple lenses that he can get a more complete system elsewhere even ethical? It's nonsense. An attempt to sound knowledgeable by introducing irrelevant information that makes no difference to most people.
