why talk of ibis In the exposed problem ?

Because a bigger image circle means a bigger and heavier lens maybe ?

why talk of ibis In the exposed problem ?

Let me expose your problem :


The DFA150-450mm 4.5-5.6 zoom is probably - after the late FA*250-600/5.6 - the best K mount zoom Pentax has ever produced.
It fills a long empty gap between 300 and >500mm in the catalog.
It goes further the "competition" in term of range covered with no sacrifice re.speed (f/4.5-5.6).
It has very high standard image quality, usefull range particularly with APS-C cropped sensor, unseen auto-focus properties and buttons (no other zoom has those 4 AF preset barrels buttons).
It has been visibly bought by tens of members in this forum.


And you come here with some fuzzy arguments : this lens is over-weighted and poorly designed, it should be lightweighted like those Canilkon stuffs, usefull for video.
Signing on that occasion your 3rd post in this forum.


Then, i argue that your reasonning regarding weight might be biaised for at least two reasons, but you don't even notice.


So i have those questions :
- do you know anything regarding lens conception ?
- do you know anything regarding Pentax system's particularities ?
- do you know that Pentax gear is definitely not the best suited for video ?


Or are you coming here only for trolls ?

Nikon 80-400 : 1360g
Canon 100-400 : 1640g
Pentax : over 2Kg

From what I can tell, the weights look like this:

Nikon 80-400 - 1570g including tripod collar but not hood
Canon EF 100-400mm f/4.5-5.6L IS II USM - 1640g with tripod mount but not hood
Pentax 150-450 - with hood and tripod mount - approx 2325g

So the weight depends on how you accessorise the lens. Monopod or tripod not included.

IMHO complaining about the lens can be done somewhere else. Please post pictures as the title of this thread says. I'm eager to see more. Thank you!

This thread is not here to discuss the lens's qualities. I will remind you all that this is for posting photos taken by this lens and further discussion of the lens here will be deleted. Thanks all.

I've started having real fun with this superb lens! Here is a sample of an airplane taken on a hot morning (full of haze) with minor PP (crop, levels, slight USM).

(It's an Indian Air Force IL-78 that was escorting-refuelling the SU-30s and a C-17 during their visit to UK, for those interested).

Nicely framed, and congratulations for your new lense.
