FA77mm vs DA70mm Limiteds - recommendations?

I am looking for a good prime for portrait use. The two choices that really stand out are the DA70 Limited and the FA77 Limited. The 77 has the advantages of focal length and lens speed (I already have a FA50/1.4). I'm looking for some feedback from people who have used both to determine if that outweighs the size and cost advantages of the DA70.

A few other details that may have an impact on recommendations -
This lens will be used for portraits with an AlienBees ABR800 Ringflash. The camera used most frequently is my *istD, so an SDM-only lens (like the DA*55) is not an option. When the camera is mounted to the Ringflash, there is very limited access to the focus or zoom rings, so an autofocus prime really helps avoid any focal length creep with a zoom.

thanks!

I'd suggest searching/browsing the forum for the *dozens* of exisitng threads discussing and comparing these two lenses.

I'd suggest the FA* 85/1.4 instead.

Since you're using it with a flash primarily I suggest the DA70. It's the cheaper of the two, and if you're using an aperture at f/4 or higher this nullifies a lot of the FA77's advantages.

Trying to search on FA 77 or FA77 didn't bring up results, so I went to a new post before trying alternative search methods.

Of course since it also gets good reviews, I will also have to consider the Tamron 90mm/2.8 (my Tamron 28-105 is by far my most used lens in the studio).

Try using Google for searches, also simply browsing the list of topics. I'm not saying this to be dismissive; I'm saying it because there is a *ton* already written on the topic, and you'll get answers *far* faster by simply looking for the existing posts. Most people who have an opinion have expressed it so many times in these threads ove the years that they aren't as likely to be jumping at the chance to do so again.

The Google method worked better than browsing the last month of forums posts. Here is the list of existing topics I found for those who ask this same question next:

https://www.pentaxforums.com/forums/pentax-slr-lens-discussion/55242-fa-77mm-...ndid-k20d.html

So overall the two lens have a lot of capability overlap, but the FA 77 will be a better match for the entire range of uses I could put it through (especially on the ME Super).

Now to find the best price (Amazon and B&H are currently showing the lowest prices).

Good job with the google search--I think there should be a sticky about all these most popular recurring questions!

Agreed.

As Marc posted above...I'm not planning to participate in any more 70vrs77 threads, and I suspect others aren't as well. So a google search is going to be far more effective.

This isn't the only forum I'm on where there can be problems with the site's search engine. Model Mayhem is even worse. A sticky with the google results would be helpful since this is a recurring question with recurring advice to search deeper since everything that needs to be said already has been and won't be repeated.

If this site isn't blocked when I'm working at a national lab this weekend, I'll do a similar compilation for the 40/43 and 31/35 comparisons. After all, I'll have my 77 by then, so I will need to look for the next lens to buy.

LBA leads me to have both. I got the 77mm first and when I got my K-x with 40mm pancake, I couldn't resist the temptation of 70mm in small form factor to go with K-x.

Now I am torn with two outstanding lens that are only used infrequently. I wish I am a photog who can justify keeping both. They are precious prime lens for portraits.

















For best value with cheaper cost, the 70mm is a no brain-er to get. If you are tight in budget and that you have the K-x, get the 70mm as f/2.4 is plenty to work with the higher ISO in K-x. If you have the K20D/K7D and that you wants the best in color, get the 77mm. Sharpness to me are outstanding in both of them. I have yet to use more to tell one over the other. In terms of color and contrast, the 77mm wins and it has that magical color rendition in both outdoor and indoor. AF is better in the 70mm and the quick shift focus in the 70mm is a handy plus over the 77mm especially in tricky scene needing manual control.

Thanks,
Hin

Sweet pics of your DA 70 and FA 77 Hinman! I was going through this debacle as well until I saw an silver FA 77 for a great price in the marketplace and bought it. I have no regrets as it is my main lens and definate goto lens for portraits :-) I love being able to use it fully on my Pentax Super Program as well!

I do not think there are many lenses Hinman hasn't tried out!

Those pictures are absolute lens-porn (all they need is the bad soundtrack music - boomchicawaawaa ).

I won't be able to duplicate those pictures, but I have the 77, and I'll have a DA40 Ltd in the next couple of days (and hopefully some time to play with my new toys when I'm not working nightshift).
