The FA50 is the better value obviously. There has been a blog post claiming that because the FA50 doesn't have it's own AF motor, it is focusing faster with the K-7 (the K-7's built-in AF motor is strong and fast). Also louder. Unfortunately I can't find the link to the comparo now. The Sigma will probably be a lot quieter.

Hate to go against the stream but I find the bokeh of FA 50 to be rather busy. dunno about sigma. DA 55 SDM had a bad review on DPReview.
Still, FA 50 is tack sharp stepped down, and the cheapest to go.

If you are buying the K-7 and the 540FGZ at the same time you should look at the Walmart package deal, $1,519.00. You'll be able to use the $25 discount as well. With most places selling the K-7 at $1300 right now, picking up the 540 for $200 is pretty nice.

Thank you
Russell

Did you compare side by side the 55 with the 50 ? You will see that the 55 is better wide open and CA is lower !

For the question,
I would say : give it a try in a shop with all of them and take that what you prefer...

?

The review was anything but bad. The reviewer really liked it and only took issue with QC and the price.

The huge 77mm front element of the Sigma would be a deal breaker for me.

The FA50/1.4 I own is a fantastic copy. I almost never shoot at 1.4, usually 2.0 or smaller, depending on conditions. I find it tack sharp, fast and the depth of field by that setting is manageable and pleasing. Bokeh at 2.0 is just as nice, if not better to my eyes than at 1.4. The price is right on the FA50...you can still pick them up around here from reputable forum members for under 200 bucks. The history and reputation of this lens makes it a no-brainer as far as I am concerned.

I prefer the FA50/1.4 because it's so much cheaper than the Sigma.

OR you could ask the camera store you are doing business with to price match. That way you would be supporting an actual camera store, which is a dying breed, instead of giving your money to the company that does 10% of the retail business in the USA. It's your call, but I would rather there be actual camera stores in the US in 10 years.

I don't know about large ticket items and Wal-Mart returns. If I have an issue I'd rather deal with Adorama or B&H then Wally-World. I appreciate the information though.

As far as bokeh I'm mostly concerned with smooth circles. That's way the 50-135 caught my attention with 9 blades.

It got "Recommended (with reservations)" and those were pretty serious reservations if you ask me.

FA50 light circles (or whatever you want to call them).








There is a wonderful example how you can control those by just varying the aperture at Pentax SMC FA 50mm F1.4 Lens Review: 4. Test results: Digital Photography Review

I've returned a flash I bought via Walmart's on line presence. It was as easy as simply going to the store and returning the item. I walked out of the store knowing my credit card had been credited with the return.

I returned a istD to Adorama and had to call them to get them process it. It had been in their procession for two weeks before I called and of coarse, I had to present proof that the shipment was delivered and signed for to the CS rep. It took another week for payment to actually be refunded.

Your call.

Thank you
