Can the FA 31 replace two lens?

Hi,

I have been dreaming about FA 31 ltd for quite a while now. I would love to own this beauty, but I must sell some of my current lens to finance this purchase. I have a DA 35that I use mainly as a walkabout lens. I like it but sometimes, I would like something faster. Also, I don't use the DA 35 for macro very much since I have a Tamron 90 macro.

No mater how good the DA 35 is, I need to sell another lens to get closer to my dream lens. I have a FA 50 that I almost never use. It's a very good lens, but I don't use it often. I like the fact that it is really fast, but a little long for indoor use. If I sell the FA 50, the FA 31 would become my low light lens. In addition, I own the DA* 50-135 which I always use for portrait.

thus, do you believe the FA 31 could replace my DA 35 and FA 50? Thanks for sharing your point of view.

I was thinking the same thing the past couple of days. I bought the DA 35 with the notion that I would leave it on the body most of the time and switch it out with my 50-135 for portraits/outdoor candids and stick on my 16-45 when I want something wider (which isn't too often). Then I picked up the DA 40 (got a decent deal I couldn't pass up) and a Tamron 90/2.8 and am now starting to rethink the role of my DA 35.

I have the FA 31mm Limited and I use it a lot indoors (definitely worth the money). I also have the 43mm Limited which I use it often for outdoor shots. Both of these are good for traveling. The DA* 50-135mm I have gets used only when I can not get close to the subject/action however, because of its size, it attracts too much attention.

I have the FA 50mm 1.4, sold it and replace it with a cheaper M-50mm 1.4. This MF lens is used mainly for taking shots of still object in low light. I am not much into macro shots yet although I have the Tamron SP90 f2.8, it doesn't get much used either.

If you can afford it, I do recommend the FA 31mm ltd.

If speed is your main concern, f/1.8 may even be a significant limiting factor.
Perhaps also consider the Sigma 30/1.4?

FA 50/1.4 is faster than FA 31/1.8 Ltd. It is not easy for me to put myself into your shoes, but unless you want Limited lenses because of the word in italics, your lens line up is pretty much complete. FA 31/1.8 Ltd (which I own) is wonderful lens. But I also have A 50/1.2 for low light, rendering and as a standard lens. Also I have FA 43/1.9 Ltd as a standard AF lens. Therefore I opine that FA 31 Ltd will not replace FA 50/1.4 and DA 35/2.8 Macro Ltd. On the other hand it probably won't hurt you too much to try. All the lenses in question are readily available from retail or on second hand market.

well,
the reasoning you are giving sounds very logical. I am lucky enough to own 31 and it's one superb lens. It goes nicely with DA*50-135 (I used to own it). If you don't shoot wider often, chances are that 31 will quicckly become your main lens. Go for it IMO.

If your main portrait lens is the 50-135, then go for it!

I have an FA 50 as my portrait and low light lens, but also bought an FA 31 to have something more useable for indoor group shots, street shooting etc. It's now rarely off my K-x. There's something special about the images it produces.

Thank you all for your advices and comments. Some of you underligned the FA 50 is faster than the FA 31. However, the FA 50 is a little long for indoor use IMHO. Is the FA 31 fast enough for indoor use without a flash? Also, some talked about the "special" rendering of the FA 31. Every picture of the FA 31 I see has a "signature". This is one of the reason I would like to give it a try. I must also tell you that another reason why I want the FA 31 is it's a FF lens. If ever one day pentax ever comes up with a full frame, almost all of my lens (the DA 16-45 being the only exception) would be usable on a FF camera. I don't like the route Hoya is heading Pentax into these days (price increase) and I suspect that a FF camera would not support DA lens. Have you noticed the new 100mm macro is named D-FA and not DA or DA*? Finally, I forgot to mention that I could sell my DA 35 and FA50 for significantly more money than I paid for it. More food for though.

I would suggest buying some pentax film cameras to make full use of your FF lenses.

f 1.8 is fast enough for almost all indoors. The focusing though is not as easy with 31mm as with 50. But if you nail the focus, 31ltd at f1.8 will blow 50 at f1.4 or even 1.8 off the water.

I second what Ash had to say. If you don't use your DA35 much - consider selling it and replacing it with the Sigma 30mm f/1.4. Although the Sigma30 is not FF neither is your DA35 and you will retain your FA50 (which is FF). Essentially swapping out these two lenses means you loose macro ability (which you have with another lens anyway) and gain a very good focal length for indoor shooting that is sharp from f/1.6 (i.e. doesn't need a flash).

I tried the A35 f/2.8, the FA35 f/2, the DA35 f/2.8, and then the Sigma30 f/1.4. The Sigma is by far my favourite lens of this bunch.

Just some more food for thought...

If he has no use for FA50 what's the poing keeping it?
When (if) FF Pentax will come it won't be exactly cheap so for forseable future APS-C should do nicely.
If he can/wants to get 31... well it's the real thing, it's one marvelous lens, and only 1/2 stop slower, and it's performance at f1.8 is just stunning from corner to corner.

Axl...I suggested keeping it because the 50mm behaves like a 33mm lens on APS-C. The OP clearly indicated that FF lenses are a preference - so it wouldn't make sense to get rid of one that is of the desired focal length in FF format.

Ultimately I don't really care what lenses people buy - I'm just offering suggestions.

I thought a 50mm has a FOV of ~77mm on APS-C.
