35mm Macro: is this a bad idea?

With Macro photography, isnt a 35mm much less useful than a 50 or a100?

If you are trying to photograph a stamp or a bug, the goal is to fill the frame with the image of the object. For an object that filled a 35mm frame at 1:1 magnification, the crop factor makes this happen at less than 1:1 magnification.

So effectively the 35mm macro just has a shorter working distance than the 50mm ... So why do we want a "normal" macro for the APS-C format again?

???
1:1 is 1:1, independent of the crop.

yeah, but the frame is smaller

what I am trying to say (and failing LOL) is that if you setup a shot with a film camera and the DFA50 Macro, then swapped the body with your K100D, then crop factor removes the edges of the image. To get the image back to the way you set it up, you have to move the lens back to less than 1:1.

Alternatively, the 35mm is 1:1 at a shorter working distance... does anybody need a macro with a SHORTER working distance?

I just dont understnad the marketing reasoning behind this lens... What need is it fulfilling? Isnt the DFA 50Macro better suited?

The same reason why Pentax has a 50mm Macro in every lens series for film cameras for the past 30 years and why a 50 or 55mm Macro has a presence in every single lens systems.

Not all macro photographies are shooting bugs. This looks to be a small and light "normal" prime with Macro capability. For other niche uses, check out this post:

last night

i was taking repros (of photos) and useing a K100D and a FA 50/2,8 macro.
If i had pictures big as or bigger than A4 i think that the reprorack isīt enough.
A macro isīt only for sky bugs.

Hey at least it won't drop the value of my FA35/2 like a DA35/2 would have ;-)

Sorry just trying to find a bright side, for me, I was hoping for a new DA35/2 with quick shift..

Olympus has a 35 macro and it has sold well. Partly because of price. Not sure a limited will be inexpensive. Although 40 pancake isn't real expensive.
thanks

At least another pentax prime of yours will go up in value

Pity I did not pick up one earlier on...

I guess Da 35mm f2.8 macro will sell a lot better since it has that edge comparing to Da 40mm f2.8: Similar in size and aperture with extra macro ability. Waiting to see what will be the 2nd limited macro to be released.

By all rights the next Limited macro will be the mighty 200! That will save me from having to buy a Sigma. Please Pentax, please.
thanks

I want a Da 200mm macro as well. I would not mind it to be limited or * or whatever as long as it is to be released

At one stage last night, I nearly push myself buying a bargain canon 500mm f4L IS ...

I want more pentax lenses!

Roentarre, I thought you just got a Pentax 200 macro? Are you wanting another? Or is there something you don't like about "older" 200 macros? More pentax people are asking for a 200 macro than the 35 macro! If there is any justice. It would give Tokina a 200 macro to sell as well - unless its a Limited. Please Pentax. I don't want no Sigma. I also want an extension tube with a rotating tripod mount like the Nikon and Olympus OM ones.
thanks

I have sometimes (as a graphic designer) need to take photos of my work, i was wondering if this 35mm would be cool for taking photos of books (small one, big ones), small posters, cd, flyer etc. ?

I think its a nice addition but maybe not the one i need the most : i would have loved a 35mm 2.0 at least. Now i just have the FA choice or the dead pricey 31 mm for 'normal' photography

so nice additon, but we want more fixed focals !

Thet only work at f22 unless your lens has an aperture ring which alot of new lenses don't.

Hi Barondia, I LOVE A* 200mm f4 macro a lot. It might be a little dark to use with exposure over 1 sec would be required on tripod at a lot of circumstances: Not all insects love to enjoy sun baths ...

I like Da 200mm macro for the sack of having autofocus with shorter lens barrel - that would fit into my Lowpro bag easily - a bonus using pentax gear having 6 lenses packed into a waist bag

A* 200mm macro f4 for normal telescopic shots is very good and I had shots on moderater Joel that showed up quite well. Very contrasty and no purple fringeing.
