Introduced in 2020, the HD PENTAX-D FA 70-210mm F4 EDSDMWR is a much lighter option for a telephoto zoom than the HD Pentax-D FA* 70-200mm F2.8 zoom. The new lensweighs in at just 891 g (28.9 oz), whereas the D FA* F2.8 lens weighs in at 1755 g (61.9 oz). Tobring the weight down the new lens is one stop slower than the D FA*.

While this lens is designed for the 24x36mm full-frame format it can also be used on cameras with the APS-C sensor format. The lens featuresrounded diaphragm blades for smooth Bokehand is aimed atshooting sports, wild life and distant landscapes.

The key features are:
*Weather resistant(WR)
* HD coating
* SP coating of the front element
*Three ED lens elements
* Internal focusing and internal zoom
* Quick-shift
* Focus Range Limiter (0.95cm - 2m and 2m to infinity)

The lens has a built-inSDM type autofocus motor and no provision for screw drive autofocus. Furthermore the aperture is electronically controlled, so this lens can only be used with cameras that support the KAF4 mount (K-50 and newer).

The lens is compatible with the HD Pentax-DA 1.4x AF Rear Converterwhen used for the APS-C format. The lens has no provision for a tripod mount.

Lens Review Date: February 19, 2020 I can recommend this lens: Yes | Price: N/A | Rating: 9 

Pros: Weight, Size, Handling, IQ, Bokeh
Cons: Cost (but this is at launch)
Sharpness: 10    Aberrations: 9    Bokeh: 10    Autofocus: 9    Handling: 9    Value: 7    New or Used: New    Camera Used: K1 MkII   

My review of this lens is not technical - there are many who are far better at that sort of thing than I am - this is simply a "first impressions" review based on the reasons I purchased it.

It is my view that this new 70-210 is a missing piece from the Pentax Full Frame jigsaw - a 3x telephoto zoom lens encompassing portrait length through to medium telephoto that is both compact and light enough for travel/walking with the added benefit of WR.

Handling: Fairly compact, not ultra light but not too heavy, yet with a solid feel - it's a lens that can be carried on an expedition without too much strain (certainly compared to the FA*80-200 and presumably the DFA*70-200) it's even a bit lighter than the DA* 60-250. The focus and zoom grips are of the recent type (DFA*50/1.4) with a nicer, grippier feel. The zoom ring is positioned at the front of the lens, this feels a little unusual to begin with but it now seems normal (although swapping between zooms may cause a little confusion).

Aberrations: Shooting with backlighting does pick out a little soft glow at maximum aperture, but detail is still retained well. Harsh/strong lighting can bring out some purple fringing - but this doesn't seem excessive and is easily removed in PP.

Bokeh: The rounded aperture blades produce a nice oof background effect on highlights and the overall look of backgrounds tends to be pleasant (not too busy or distracting). I've got a couple of outdoor portraits where the subjects are beautifully sharp and the background really has a lovely, smooth look - they stood out (to me) as special shots.

Image Quality: Although this is not a Star lens it should not be a lens of compromises, so I would expect it to perform well at it's extremes and in poor conditions. It doesn't disappoint in any aspect - the long end of the zoom range doesn't soften notably (as some do) and shooting at maximum aperture produces consistently excellent results. I've had the Grandkids over a couple of times since I've got this lens, and it's been a revelation in its ability to get such a high keeper rate with indoor conditions (something my DA*60-250 couldn't manage).

Focus: I haven't experimented with the focus limiter yet, but the AF is quiet and very quick (notably quicker than the DA*60-250) across the range and I haven't found any situations yet where it "hunts". It's quick to lock focus and is accurate. AFS-C still isn't perfect (I know this isn't just to do with the lens) - keeper rate with the Grandkids on the swing wasn't too bad but not great.

Other: The close focus and reasonable magnification will be useful in quite a few situations - whether it can replace a macro for travelling is yet to be seen. Coupled with the HD DA 1.4x WR converter this lens is surprisingly good, IQ holds up - with a little softening particularly at the edges/corners - but the amount of vignetting is surprisingly small and with PP it can be removed almost entirely. Having a constant aperture is a nice feature, particularly with no drop in quality at the long end.

Here are three "sample" images from the first day or two of use (around the garden and house) - they certainly don't show what the lens is fully capable of but will give an indication of how it handles some lighting situations.

1. 1/200, f4 @ 210mm

2. 1/100, f4 @ 70mm

3. With DA 1.4x WR converter - 1/125, f4 @ 210mm (f5.6 @ 294mm) 1600 ISO + PP

Hope this helps someone

Lens Review Date: February 16, 2020 I can recommend this lens: Yes | Price: $1,200.00 | Rating: 9 

Pros: sharpness, handling, weight!
Cons: price
Sharpness: 10    Aberrations: 8    Bokeh: 10    Autofocus: 8    Handling: 9    Value: 7    New or Used: New    Camera Used: K1II   

Sharpness at infinity: In the center the lens is sharp wide open at all focal lengths. Only the extreme corners are a litte bit soft wide open, but ok when stopped down to 5,6. Sharpness is excellent between f5,6 and f11 (on par with DFA* 70-200).

Sharpness at minimum distance (0,95m): In the center the lens is sharp between f5,6 and f 11. But at 210 mm and 0,95m only a small center is really sharp!! Even at f11 not only the corners are blurry. Avoid the range between 0,95 - 1,2 m at focal lengths >150 mm if sharpness is important. Instead, I suggest an achromatic close-up lens. Sharpness was excellent in combination with an +3 Soligor achromatic macro lens, even at an magnification of 1:2. .

Sharpness in combination with the DA 1,4x Converter is very good in the center. Only the extreme corners get blurry and darker.

Flare control is very good (on par with DFA* 70-200).

Handling at the K-1 is ok. Build quality also.

AFspeed ist good and mostly accurate. But sometimes af stop working at position 0,95 m.

Price in Europe (1200 ) is much too high compared to the price ot the Tamron Versions for Canon and Nikon (500).
