Thread reopened with change of title.

The title tends towards trolling.

Anyway, lets dissect this :

Small - Really?
Its just a bit shorter a flange distance while having rather large diameters.
The 35/1.4 is a 52mm dia
The 14/2.8 is a 58mm dia
The Pentax 35mm and 15mm offerings are 49mm (you can even share some ND filters)
How often does one use f2.8, trying to dig less DOF out of a FL that will be hard to give less?
Right size for the typical use is what defines the Pentax lenses like the DA15/4 which is small and more typically used stopped down.
Add the long lenses to the fray, and there is no advantage at all in size.



Fast - Ok
Pretty clear advantage of designing from ground up for a system.
However, note how most of the lenses are mostly weighted towards center sharpness.
Again, a trade off between size and more even sharpness which the user has to determine which is preferred.


Cheaper - Really?
B&H prices
DA15ltd - $546
XF14/2.8 - $899 (oh.. and you need to buy a hood)

DA35/2.4 - $107
XF35/2 - $399

DA70/2.4ltd - $372
XF60/2.4 (macro) - $649

There isn't any size advantage (in fact Fuji options clearly loose in size) past 35mm options.


The CDAF can be more accurate but Fuji X series cameras have been an over promise in AF capability to me since the XP1.
Every iteration or FW update, they claim better AF, but in the end, from my own real world use indoors, I've never found that its better (still very 'CDAF' with the shifting confirmation )

My personal followup and initial report: https://www.pentaxforums.com/forums/10-pentax-slr-lens-discussion/311733-syst...-40-100-a.html

I'll continue with more Pentax impressions there, and here I'll add some comparisons with more Fuji details.

What's pleasantly surprising about Pentax lenses compared to Fuji...

-- Pentax lenses come with pouches. Fuji's ones come at most with a cloth bag.
-- Fuji lenses have apertures in constant motion. This is by design. When you close a lid, which I always do, the apertures open wide. When you remove the lid, they close down, but the sensor takes a second or two to darken. If you are using an optical viewfinder, such as X-Pro1 or X100*, you may not notice it and if you take a photo right after removing lens cap it may come out washed out. I like the fact I can remove a lid from Pentax lens and take a photo at once in any light.
-- Fuji lenses are focused by wire, and they've became very very good at it. The focus ring feels natural and even better than some manual ones. Fuji focusing is now sometimes as fast or faster than some of the screwdrive Pentax lenses. Since my original X100 in 2011, when focus by wire was quirky, the progress is huge.
-- Fuji autofocus on X-T1 is often as good as Pentax on K-3II, and sometimes faster, but sometimes slower. Firmware 4.00 on X-T1 was a gigantic leap forward.

Tomorrow Fuji will launch what looks like X-Pro2, and we'll see how that one compares!

A+

OK, Fujifilm launched X-Pro2 yesterday, and it is also a 24MP camera with even faster AF. The 100-400mm was also released. I'll see how the systems compare when I get it, but in all cases both are complementary and fun to use.

That X-pro2 looks interesting, but out of my budget. It was, however, interesting to see everyone over on the Fuji forums so excited last night. I imagine there will be a bit of excitement going on here in a couple of months, as well.

Just a little bit.....

[TinaS]

That one will be out of my budget too, but I'm excited for everyone who waited so long for it.

Yep, same here

[skankin_giant]

Can't see me upgrading anytime soon, had my X-Pro since 2013 and not seen the need to change it yet. The only thing I would want is some weather sealing, but as none of my lenses are there is little or no point in upgrading for me.

What is the Fuji version of the A-400 like?

Fujinon XF 100-400mm F4.5-5.6 R LM OIS WR.
Well, it has AF...

[Zygonyx]

It will, once released

[Digitalis]

Fujinon XF 100-400mm F4.5-5.6 R LM OIS WR.

a slow as hell consumer lens apparently, no competition for the A*400mm f/2.8 ED [IF]

[Zygonyx]

Pentax should really upgrade that last one

[Rondec]

Takes Fuji a long time to update their bodies, doesn't it? Sony, Pentax, and Nikon have had 24 megapixel sensor bodies for a long time. Sony NEX 7 came out at the end of 2011. I'm sure the X Pro 2 will be a nice body and will upgrade capabilities from where the 1 was at.

[Doundounba]

Fujinon XF 100-400mm F4.5-5.6 R LM OIS WR.
Well, it has AF...

It's more aimed against the 150-450mm F/4.5-5.6, IMHO. Lose 50mm, shave 700g - not a bad trade-off, IMHO. Looks like a nice lens to me, and launching at a lower price point than the 150-450mm did, though the Pentax is actually a bit less expensive right now, and Fuji don't seem to lower their prices much with time...
