FA or F 28mm ?

Having just bought the DA12-24 & DA 35mm F2.4 I'm beginning to think that my
DA17-70 is going to be little used and I'm thinking of using this as a good excuse to sell it and buy a 28mm prime instead.

I know there are quite a few manual options in 28mm but I much prefer autofocus so my options seem limited to the FA 28mm & F 28mm, I'd appreciate any feedback on these?

thanks

Simon

Take a look at our lens reviews- it looks like the F version scores an entire point higher, despite not having an AL element!ttt

IMHO The 28mm and 35mm are not different enough in practice to justify owning both.

I like the A 28mm 2.8 quite a bit, which should be identical to the F 28. It's not a particularly colourful lens (for whatever reason) but it's damn sharp with nice bokeh (reminiscent of DA ltd. bokeh). Really nice for landscapes and snapshot photography.

Remember that the review section is HEAVILY dependent on price paid. Therefore an older 30 dollar lens has a better review than a newer 100 dollar lens with the same optics. In my experience, anyways. If the F 28mm is cheaper than the FA 28, that might explain the difference.

Since you have the excellent 12-24 AND the 35mm, I think you might want to consider something like a 50mm 1.7/1.4 or even something longer like the 100mm macro or the DA 70?

Aspherical elements do usually contribute to uglier bokeh. Sharpness and low distortion isn't all.

it was reported that the F is slightly better than the FA. having said that, why don't you go for the Sigma 28/1.8 instead?

The FA used to have a better reputation than the F version until a few years ago. Now it's the other way around.

28mm lenses are pretty common but the F28/2.8 is getting harder and harder to find. People who have them simply aren't parting with them. I have the F28/2.8 and A28/2.8, the "F" version is simply a better lens than the "A" version. It's sharper with better colors.

Actually I used to have 2 F28's including a brand new one. I just sold the new one before I even got around to putting up a FS ad. Both the F and FA 28's are destined to hold their value very very well I think.

I sold my FA28 and regret it now. Lost contrast a bit at 2.8 but the detail was there. The lens has had its detractors (not sure how many have actually owned it) on forums but I though it was good.

Interesting, since it seems they share the same optical formula. I wonder why such a noticable difference...sample variation? different coatings? MF v. AF accuracy / precision? different glass, even though the same optical formula? Hmmmm.

well i own the da 30mm f2.4 and love it the autofocus is very quick but the ony thing is that it does not have the extra shift focus ring when in auto focus but like i said it is great when in auto mode i would say 9 out of 10 times it focuses on point, great lens in my opinion if you have the money buy one you will be very happy on the other hand i do have a manual 28mm f2.8 lens that i hardly use because my new 35mm lens they are both very close in range that when i do use the 28mm it is for still life shots more or less so a bit of info to you hope this helps you find your lens

Since I owned a m28/3.5 I did use the FA28 hardly anymore.
Rather would buy a Sigma 28/1.8 for people or a m28/3.5 for landscape.
But sice you already have a DA12-24 I do not see the benefit of an extra 28mm
unless its for shallow depth of field. The FA28 is certainley not at its best at 2.8 or 4.0.
