FA20-35mm vs DA16-45mm

I've read the reviews in the database and read some of the previous threads on this, but assuming you could purchase either lens for around the same price, which would you go for?

According to photozone, both show high levels of CA, even when stopped down. Which is easier to correct if necessary?

Thanks

it depends on which focal length that you would need or require or something that doesn't overlap your existing lenses with similar focal lengths. another reason would be the size factor. the FA20-35 is virtually small compared to the 16-45. I prefer the 20-35 due to focal length needs and size.

I know the 16-45 will be a bit wider but I think 20mm would be comfortable enough for me. I do like the smaller size as well.

I never had the 16-45, but I did have the FA20-35 and it was quite good - I really liked it. I only sold it after I got the FA20, FA31, and DA*16-50.

You wouldn't have any sample shots I could look at? Something that might illustrate how bad the CA's are uncorrected would also be worth a look.

Thanks

I had both lenses. In terms of versatility, the DA 16-45mm's wider zoom range has definitely the edge over the FA 20-35mm. In terms of build quality, both are about the same, though I have seen used DA 16-45mm lenses with overly loose zoom and focus rings.

The 20-35mm is very compact and doesn't extend very much when zoomed whereas the 16-45 has the quirky lens barrel extension at 16mm which affects the pop-up flash. If you still use film cameras, the FA has the wider usable image circle.

Optically speaking, the 16-45 has a slight edge in terms of contrast but the 20-35 has a very punchy color rendition. The 16-45 is pretty even in terms of sharpness from center to edge and distortion is not that excessive. The 20-35 is quite sharp but does show some noticeable barrel distortion at the wide end. Personally, I find the zoom range for both the 16-45 and 20-35 lenses to be too short and opted for the Sigma 17-70mm and currently the DA 17-70mm which has a far more versatile zoom range.

I love my 20-35. I have noticed very few pictures with CA, although perhaps I haven't been looking hard enough. For me the size issue trumps the better range of the DA lens, although I have never had one.

Here's a thread with some sample pictures, if that helps:

The 16-45 mm is my workhorse. It's my sharpest zoom (vs. 18-55 II, 18-250 and 55-300mm). It is a bit clunky, but the range is much nicer than a 20-35. On the long end, it just scrapes into classic portrait range at 70mm equivalent, whereas the FA's long end is a bit short for portraits. I find that 18mm is not wide enough for landscapes and architecture, 20mm would not do. I've never felt a need to remove CA. Note that digital cameras from the K-x onward can correct for CA's and barrel distortion on the DA 16-45, but not on the FA 20-35.

yeap..because DA lens already set in memory in Pentax late body .. im also notice this feature also in K-7 ...


and also this is an example from DA 16-45 if you can notice the difference from FA 20-35 ... ... in 16 mm you will see the difference ...

I think color is the most important characteristic I look for, assuming a lens has adequate speed and is fairly sharp about 1/3 stop from wide open - which is exactly what I found with this lens.

For digital work, I don't see any reason to use 20-35mm - not as wide and not the same reach and quality-wise not really superior.

The only reason for that lens is film use or dreams of FF.

Actually, I just started shooting with my recently acquired 20-35 - maybe I have a good sample, but mine is sharp as hell. and f4 is not really limiting with the K5.

At the price I paid, it seems a way better value than the 16-45, especially as it will become a true super-wide on the MZ-s i plan to acquire one of these days... samples to come soon.

I think they are both darn good lenses, and it would be hard to go wrong with either. The 20-35 is pretty fun on film, though. And while an MZ-S is indeed an incredibly sweet camera, I think I would spend $30 or whatever on a zx-5 or zx-7 first. Even a PZ-70. FWIW!
