I saw these 2 converters on bhphoto. I had the 2nd one on order for A*300/2.8
Pentax 2.0x L Teleconverter$550 US Dollars!!
Pentax 2.0x S Rear Converter A (Teleconverter) for K-Mount
How much difference is there between the two teleconverter besides the price? Though the first one is designed for A* series, I wondered how much difference is there if the 2nd one was used?
I am just trying to justify myself for the purchase of 2X L teleconverter as it is quite expensive. Most of the teleconverter 2X are considered crap regardless what companies make them but I have never seen a teleconverter costing an arm and leg here.
Hope people can help me out regarding the quality difference between these two adaptors or I would just invest my money into macro stuff soon...
Thanks everyone in advance
James
