Macro for under 150$?

Hi all, I recently got a pentax k-10d from my grandfather. I have the 18-55/3.5
and the 55-200/3.5. I am mainly doing aquarium photography, but I would like to get into macro aquarium photography. Old lenses are great, manual focus would be best for me. Thanks. The main reason I have a 150$ budget is becdause I'm 13 lol.

Thanks

PS used from ebay is fine

I have posted this before

I have 2 macro solutions that cost less than $150.

the first is an SMC-Macro_Takumar 50mmF4 lens ($90) plus a set of M42 extension tubes ($6) and an M42 Focusing Helix (fariable 15-30mm extension tube) ($4)

The second was a DIY project, starting with a Miranda Bellows ($25) a set of miranda extension tubes ($3) a flanged M42-Kmount adaptor ($6) and a 135mm Enlarging lens ($100)
the entire kit is shown below.

It required setting the enlarging lens into a T mount adaptor ring with epoxy, and removal of the miranda screw thread from the camera side attachment plate and epoxying the flanged adaptor to the plate. The rig is shown below.

Since the lens is mountedd on a T mount ring, I can attach any T mount lens to this. I also have an M42-Tmount ring, so I can put, for example, my 50mm macro on this and get much more than 1:1 (I figure 1:6 approximately)



I also have an SMC-M 100mmF4 macro and a set of K mount extension tubes, but that cost me more (in 1986) than $150 and I am not sure of current pricing on the 100F4 lens

Hey--it's great to hear from you. My younger son is 14, and you remind me of him:

My first macro lens was the Phoenix/Vivitar/Promaster/and I think, even Pentax labeled 100mm f3.5 macro. They were sold under the above brand names in manual and auto focus versions. They were 1:2 with a 1:1 adapter lens included. They are cheap (around $100), plastic, and surprisingly good for the price. Look in the lens database under misc. and you will find the Phoenix version.

Another option: Cosina 100mm 1:3.5 : Cosina 100mm F1:3,5 MC Makro Lens Reviews - Pentax Third-Party Lens Review Database, see also: http://www.photozone.de/pentax/368-cosina-af-100mm-f35-macro

The same lens has been sold under other brands such as "Phoenix" and "Promaster" at least. I got the Promaster MF version for US$ 82. This was new in box, and as such included the 1:1 adapter without which this is 1:2 (50 % of life size on the sensor, same as the Pentax-M 100mm).

Here is one currently on Ebay (NIB): Cosina Pentax Macro Lens AF Macro 100mm F3.5 bei eBay.de: For 35mm SLR (endet 23.10.10 22:32:21 MESZ)

and another:

http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=310263745632

Both are from UK but are apparently willing to ship abroad.

I have seen a few old Tamron Adaptall 90mm f/2.5 macros on ebay recently selling for just over $100 and you can often find P/K adapters for around $20.
This will get you a great 1:2 macro. If you need 1:1, you can add the Tamron Adaptall 01F 2x TC and you'll have a nice 180mm macro that does 1:1

I recently picked up a Sigma 50mm f/2.8 MF for $100 off ebay. It's a great lens for a cheap price...and who really need AF anyways for macro?!

I think I goofed up the second Ebay link to the Cosina 100mm 1:3.5 above. It should be fixed now. This offer is for a used lens and since the 1:1 adapter lens is not mentioned, it is probably not included.

With the 1:1 adapter the focus range of this lens is about 6" - 12" from the front of the lens, where you get 1:1 (live size on the sensor) at the minimum distance. Without the apdater you get 1:2 (50 % of live size on the sensor) at the regular minimum focus distance 0,43m (~17") and less at longer distances in proportion (e.g. at 0,86m (= 2 x 0,43) you would have 1:4 (25% of live size on the sensor)). The Cosina would seem to be good for a typical home aquarium tank with which 1:2 should be good provided that the fish aren't tiny (much under 1" or so, which is roughly the APS-C sensor width). This is worth pointing out as you might have different kind of tanks or fish in mind in which case the Cosina might not work for you.

Welcome to the forum.

Sigma 50mm f2.8 (1:1) definitely. It has the 'A' Setting which is very helpful. Very sharp and easy to use. Relatively inexpensive too. I paid $130 for mine.

Tamron 90mm f2.5 adaptall (1:2) if you can find one for a good price. I recently picked one up with a minor blemish on the front element (water spot of some sort that doesn't affect IQ) for $70. With the 01F teleconverter you can get to 1:1 without decreasing distance to subject or affecting IQ. You just loose 2 stops. Should cost an additional $25 to $30. Don't forget to get a Tamron K mount adaptall for it. That will run another $20 to $25. So all said and done you are looking at $125.00 to $150.00 depending on the condition of the lens.

Also, the the Pheonix/Vivitar/Promaster/Pentax mentioned above is not a bad choice if it comes with the matched diopter for 1:1.

For best IQ - Sigma
For best distance to subject - Tamron

Depends on what you are doing. If your subject has legs and eyes and is likely to use them to get away from you, you're best served getting the Tamron. If the subject is dead, inanimate, or otherwise unable to escape your advances, the Sigma will be the best option. Of course, with the sigma you will have to be mindful of your light source because the front of the lens gets within inches of the subject at 1:1.

For fast, excellent inexpensive results I recommend you add a $50 Raynox DCR150 to your long zoom lens. All your automatic camera functions will work including flash, and you'll magnifications up to about 1.5x at a working distance a little greater than 8".

For examples of what to expect see: https://www.pentaxforums.com/forums/pentax-slr-lens-discussion/74221-raynox-macro-club.html

OR, go in the direction Lowell suggests with:
A used type K bellows Macro Fold Bellows for PENTAX K-m K20D K10D K200D K100D - eBay (item 230471079193 end time Nov-01-10 21:09:46 PDT)
An m39/K adapter PIXCO Macro Leica M39 Lens to Pentax Mount Adapter - eBay (item 200531656275 end time Nov-14-10 02:15:43 PST)
An enlarger lens 75-135mm Rodenstock Omegar Omega 75mm 4.5 Enlarger lens - eBay (item 170545649740 end time Oct-26-10 13:46:45 PDT)

This approach will yield superb macros that are in-focus edge-to-edge at the cost of losing all automatic functions.

Dave

PS an added advantage to the Raynox clip-on is that it is small & quick to mount on a lens; I carry mine all the time even though I've got some really good macro lenses.

Hmmmm.......I never noticed the Raynox adapters. Something to look into since the adapter can clip onto any lens with 52 to 67mm filter threads.
