Firstly, I would like to Thank you all for taking time to answer my questions, seeing the info I'm pretty much back to go with the Pentax system, especially taking the present price and the features into consideration. Coming to my photography I'm just an amatuer, I will be taking intra-oral pictures using a ring flash.
Can anyone suggest a good macro lens (1:1) to which I can attach the ring flash,also sharing their experiences here will be great. Thank you all once again.

As far as macro 1:1 lenses - there are several available. I happen to have bought a Vivitar Series One 105mm macro that I love, but it's manual focus/auto exposure (doesn't bother me, but it could bother others). Every so often you'll see theLester Dine (Kiron)dental lenses for sale (they are the same as the Kiron/Vivitar S1 105mmmacro lens but it has marks connected to dental photos on it instead of ratio to subject). They are outstanding lenses if you can pick one up, but are also manual focus (not sure if there's an auto exposure version). Since you are talking about intra-oral photos you might find one very useful - something to keep an eye out for on ebay.

For more modern lenses - the Pentax 100mm macro has an excellent reputation, the Phoenix is quite good for very little money, but it comes with a matched adaptor that allows it to do 1:1. If you buy one used, make sure they sell the adaptor with it. The samples I've seen taken with Tamron's 90mm macro lens is also outstanding, all of them are capable of 1:1 (Sigma makes one, too). You'd have lots of options available.

Coming to my previous question about MACRO LENS, can the smc pentax DA 70mm f2.4 lens be used with 1:1 ratio, I want to buy a lens with AF so tht I can use it even for the portrats...
Thank you

The DA 70 is not a 1:1 macro lens. You could add extension tubes to achieve the 1:1 ratio, but you will probably end up losing AF unless you spend a small fortune. I believe Kenko makes some that will maintain AF but are in the in $150 neighborhood.

Thank you Ishino, after doing all the so called research I was convinced that the Tamron 90mm macro would meet my requirements, ordered it yesterday ...can't wait for it now,

Hellooo...

Like everybody I'm one of those confused souls unable to decide about my next upgrade from point & shoot to slr camera....I have been going through all the reviews and the comments made in this forum and decided to go with the Nikon D80, but after further study I found that Pentax K10D has some excellent reviews and with the current price its a steal...., when I almost made up my mind to go with pentax, I was told that the FLASH is not really that great....this somehow made a setback..so I would like some feedback about this.....any info about this is appreciated.

Thank you

Kriss

This should clarify a lot of your understanding

It was D80 compared with Pentax
