Which is the best macro lens for my K-5?

I have a K-5 with the Pentax 18-135 lens and the best Sigma 10-20 lens.
Now I am thinking of getting a macro lens too.
Which is the best macro lens for my K-5?

Best regards,

Sten

Best? I like the Pentax D FA 100mm Macro becasue it is relatively compact yet allows for some distance to the subject even at 1:1. Image quality is excellent. The older F and FA lenses which are available used for less than the D FA has the same optics. If you want to go to higher magnification than 1:1 using bellows or extension tubes then a lens with an aperturering is a must.

What do you want to shoot macro? If flowers, insects, etc, then I'd go for something around 100mm - the Pentax 100mm WR - but if still life, then there are the 35 and 50 Pentax macros.

That said, plenty of people like the Tamron 90 and Sigma 105, so at the end of it (a) working distance to subject and (b) price are probably the determining factors.

Agreed. DFA 100 WR is a winner macro lens. I have the FA 100/2.8 macro and even that lens is simply stunning in my eyes. With it, I won't be replacing it with any other macro. The DA 35 macro is also highly acclaimed but is a very different lens given its unique focal length for a macro lens.

You may want to read the following in-depth reviews:

Tamron 90mm Macro vs Pentax 100mm WR: Review - Introduction - PentaxForums.com

Pentax-D FA 100mm F2.8 WR Macro - Review - PentaxForums.com

https://www.pentaxforums.com/reviews/pentax-da-35mm-f28-macro/review.html

You already received some good advice. What do you want to shoot? What focal length do you need?

There are the Pentax 35mm macro, the Pentax 100mm macros (D-FA as well as older lenses), Tamron 90mm, Sigma 105mm (now discontinued).

Many PF members seem to like a macro lens about 100mm and the Tammy 90mm and Pentax D-FA100mm are both great lenses. See the comparative review.

Hope that the info may help...

The best?

My 100mm WR has been a real workhorse for me but I just got my new Zeiss 50mm f2 Makro-Planar two days ago and it is a real treat to use. The colour, how it renders the out-of-focus areas and build quality are all simply wonderful.

It's tough to recommend "the best" as you haven't stated what you need/want a macro lens for...? (Insects, flora, copy work etc). Is auto-focus important to you?

In my opinion, and for my needs the Zeiss 100mm f2 Makro-Planar would be "the best", if only I could part with $2200+ needed to get one...

Thank you all so much for your excellent response! I am now leaning towards the Pentax D FA 100 mm WR macro lens.

Best regards,
Sten

This. I have two macros that I use for different purpuses, though both are 90mm f/2.5. One of them only goes to 1:2, but is razor sharp from f/2.5 to f/11. Excellent for not-quite-so-close macro, as well as an all-round short tele. The other one goes down to 1:1 and is tweaked to look its best from f/8 to f/16. When shooting small macro, DOF really matters. If you want all of that really small insect or interesting flowerbud in focus, you'll be wanting to shoot around f/10 and up.

I've been interested in the D FA 100mm f/2.8 WR myself, but after reading that it fares poorly in smaller apertures, I don't think I'm going to get it for macro shooting.

small macro
Pun unintended. Why couldn't we just have called it micro like Nikon did? It's so confusing.

I have no clue where you read that, all I can say is don't believe everything you read on the 'net!

It also depends on your side-interests. Obviously you like macro-shooting, but if you are interested in portraiture too, then don't get the the DA35ltd, but the (D)FA 100mm. Which really double as an excellent portrait lens.

But if you're also in need of hypersharp walkaround prime, then the DA35ltd might be a good option.

Yes, a macro lens which is also good for portraits would be fine. So the Pentax D FA 100 mm WD macro looks good to me.

I understand you asked about 'macro,' but your responses seen to suggest you may be more interested in extreme close-ups. While the D FA 100/2.8 (both WR and non-WR) are good picks for that use, my favorite for extreme close-ups is the DA*300/4. It's not cheap, but it will not let you down. My 'go-to' field lenses are the DA 300 and D FA 100. If cost is an issue, look for a used non-WR version of the 100. It has the same optical formula as the WR and is excellent, as well.

Cheers...

Sigma 70mm macro

I recommend the Sigma 70mm F2.8 EX DG macro. It's heavier than the Pentax 100mm F2.8 but easily matches its IQ (I have both). It is an extremely sharp lens and said to be one of the best lenses Sigma has made. I find it ideal for both portrait & macro....
