I have the 31mm and the DFA 100mm macro - with the full frame coming out, I'm considering the 43mm to give me a semi wide angle, normal and a telephoto/macro option - What are your thoughts?

jimr-pdx · 05-03-2015, 10:33 PM

Personally I would try a more even split, like the DA*55 between the two. Or plan to add 43 and 77 both to the mix!

Totally your preference though, perhaps you tend to lean to wider shots and the 31-43 spacing is just right.

I didn't get the 43 because the reviews using APC cameras was ordinary. Maybe wait until you have your FF in the hand and others can review the 43's performance on a FF. I had the same dilemma until they announced the K3 II. Looks like I will get the new K3 instead and dream about the FF with my 31mm a while longer.

28-31mm are my favorite focal lengths for "normal" primes on APSC. These lengths translate into 42-46.5mm on FF.

To me the FA 43 would be a smashing prime on the upcoming FF.

Get it now before the prices jump even higher!

That's my fantasy, too.

Full frame has a sensor that is 24x36 mm large, like the 135-film. That means that the diagonal is 43 mm. So that lens gives you the same perspective as your eyes, and is the reason why they made such an odd lens. Under 43 is strictly wideangel, above is tele lens.

Billk · 05-04-2015, 04:10 AM

I have the 43mm (on a K7) and really like it. Once I get my FF I'm sure i will like it even more.

robthebloke · 05-04-2015, 04:21 AM

The 43mm is seriously underrated. The 31 and 77 steal the show, but the 43mm is still a magical lens. If you prefer a smoother bokeh, then the DA 55 may be a better option. If you like lenses with character, then get the 43.

sungibr · 05-04-2015, 05:08 AM

I recently shoot a roll of film on a K1000 with a mix of lenses, being the 31mm one of then and, despite it is a wide lens, it fits very well on a FF body. I liked the results, although the focus screen of mine K1000 is a little miscalibrated.
Field of view, bokeh, sharpness and "the look" are very pleasing, to my liking. I'm eagerly waiting to see it in a Pentax FF DSLR

pinholecam · 05-04-2015, 07:09 AM

Its more of a personal usage decision.
You need to try or know if you like the 43mm FOV.

I liked the 43ltd on aps-c very much.
On FF, I needed to "re-learn" its use.

I would suggest just looking at a 50mm as well.
If you want the shallow DOF 'look', the 50mm does it better.
The 43ltd somehow does not seem to do it as well. (due to FL, f-stop, working distance perhaps) .

On the note about performance.
I don't know where that ding against it on apsc comes from.
Its certainly one of the sharpest lenses I've got, getting very sharp from f2.8 onwards.
Certainly no problems on FF too. (proven with use on A7 and not just speculation

)

For all intents, it's a full frame lens. It will vignette at F/1.4, but like a normal ff lens does.

Personally I would go with the 43 myself.

chti · 05-04-2015, 11:28 AM

I have the 3 FA´s: 31/43/77. I can recommend all of them and I´m really looking forward to use them on FF.
The one I use the most on APSC is the FA 43, especially for portraits along with the FA 77. The 43 is sharp wide open, tack sharp at f2.8. I´m curious to see how the field of view will be on FF. Guess it´s gonna be a great "normal", small and light-weight lens.

Enrique S Toso · 05-04-2015, 01:34 PM

I believe that the FA 50mm F1.4 will be amazing in the FF body. Maybe just a little CA full stoped, but a sharpness beast in F4. Same the tamron 70-200 F2.8. The 3 amigos are amazing even in a pinhole camera made with a shoebox, lol.

Im afraid there is a lack of normal f2.8 zoom options in the legacy lenses.

**monochrome** · 05-08-2015, 10:39 AM

I'm traveling to 'old money' Florida next month. My travel bag will have the K-3, the three Princesses - and an MZ-S in a side pocket.

LBA aside, I really don't think I need any other gear.

Results from the MZ-S will tell me whether I 'need' the FF.
