Hi, just bought my first two lenses, of course they have different filter diameters (72mm and 52mm).
And of course I plan to acquire new toys in the future and they'll certainly have diferent diameters too.
And... I'll use filters (I already do for my older camera)
- neutral / UV filter to protect the lens
- for this one my strategy is : buy a good filter for each lense that "diserve it"
- polarizing filter almost certainly
- ND filters
For the ND and polarizing ones I'm wondering :
- should I plan to buy one set (say a 77mm set or 82mm ?) and adapters 52 => 77 and 72 => 77) ?
Do you have different ND / polarizing filters for each of your favorite lenses or a similar strategy ?
Thxs

well well well... and the winner is...
I'll try the 16-85...
cons (for me) : doesn't have the ring with the distance (for MF at oo)
pros (for me) :
- the range 16-85 is just over what I use now,
- 16mm - 20mm = f/3.5
- 21mm - 30mm = f/4
- building : WR (and thanks audiobomber post)
- own taste : (wen't to a store do see IRL the products) the "touch" is more pleasant, the AF felt better (not scientific or rationnal)
It's new, havn't been tested yet and I think I won't read reviews untill I made my own opinion on strenght and weaknesses. At the end of the day is there un more important fact that : "makes goods pic for me or doesn't" ? :D
almost on my way... thanks to all for the help !

Thx for the tips, for what I read, the 16-80 compare to the 17-70 would be :
•16mm - 20mm = f/3.5 => faster
• 21mm - 30mm = f/4 => the same
• 31mm - 67mm = f/4.5 => slower
• 68mm - 85mm = f/5.6 => much slower (but that would be ok for me, 68mm (equiv 100mm) il already quite a long focal for me... I'm just interested with the 16-85 in the possibility to shot from 50 to 85 without changing the lens... I won't open the debate here on wich lens for 50-135 o 50-300... :cool:

Just a precision : my use is mainly wide angle, I use now an equivalent 28-118mm and shoot most of the time at the lowest focales.
I did :p, I just spent last two days in lens reviews and databases...
I understand and I do agree... but I just can't wait :cool: any more to get my first reflex (and there is an cashback offer only until january the 10th, and I'd prefer start with a fully 100% compatible solid blablabla lens => pentax, WR)...
I read the review DA 16-85mm, wich looks ok for me since "my" more important is on wide angle
Thanks DSim for your comment, I have see some pictures taken by the 16-85 mainly K5 pentax da 16-85mm photo samplesl, but I found very difficult to decide on these how do they compare to 17-70 ;) (and they were taken by a K-5 not K3)
[saw also : https://www.flickr.com/search/?tags=hd1685mm says K3 / 16-85]
I understand the point on f/4 vs f/3.5-5.6. But at the end it is about only one stop less than the 16-50 f/2.8 on the same range, not so awful for my use.
•16mm - 20mm = f/3.5
• 21mm - 30mm = f/4
• 31mm - 67mm = f/4.5
• 68mm - 85mm = f/5.6
Looks like many pentax fans are quite disapointed by this pentax choice for the news lens, but.... "you can't always get what you want" (RS)
Clock ticking, so either I go to the cheapest first, with the 18-55 WR kit and wait to get a better lens (new or used), or I go directly to a "correct" first lens and will have more time to 1) learn and practice K3 and 2) whatch out for good used opportunities.
Up to now my thinking is :
- 18-135mm WR (kit) => in that case I'd probably go for the cheaper 18-55 kit knowing that I'll look for better lenses in a very close future
- 18-270 : I'm convinced by the review I'd prefer the 18-135 WR over it (or a not pentax equivalent) so... see above ;)
- 16-50 f/2.8 => pentax forum reviews tends to show the tamron would be a better start but not WR and not Pentax
- 12-24mm f/4 or 20-40 f/2.8-4 : more expensive, less polyvalent, (12-24 not WR ?) => don't look like a first lens but sure I'd love those...
That's why I'm still thinking, but I resumed my problem to :
- go for the 18-55 WR (kit) => very cheap in kit, a not so expensive "waiting lens"
- directly go for the 16-85 or the 17-70, in this case probably the 16-85 because it covers the focales I use now and weather resistant (coherent with K3).
Perhaps the decision will rely on bargain power, if I have a good deal in my shop I'll go for the 16-85, if they stick to their prices I'll start with the kit...
Thanks al for your helps I'll keep looking for updates for a few hours before deciding tomorrow max...

I understand 16-85 is WR when 17-70 isn't, and they are more or less the same dimension and weight.
Hi, for those of you who have tested the 16-85mm, did you have the opportunity to compare it with the 17-70mm f/4 ? is it better at wide angle ?
In terms of image quality why did/would you chose the 16-85 over it? thanks
