Originally posted by BigMackCam The Tamron 60-300 is a lovely old lens. I have a mint copy, and I'm surprised by how good it can be optically. But even my non-PLM HD DA55-300 runs rings around it, so given that the PLM is reputed to be better still, I think you'd be extremely satisfied with it
I have ordered my new 55-300mm PLM. Now the decision is what do I sell to help fund the purchase? The following list in decreasing order of pain for an addicted Pentaxian
1. Sell the Tamron SP which is joy to handle and delivers magnificent images, but is long and heavy (and only cost me $50 with the mount)
2. Sell the M 80-200mm/4.5 which is a classic Pentax lens and balances beautifully on the K70. That one cost me $70.
3. Sell the DAL 55-200mm, which is not so sharp but is really light to walk around with all day
4. Sell the Sigma 18-250 HSM and commit to always carrying at least two lenses
5. Sell a couple of very old lenses that may not fetch very much, but I will probably never use now - Sigma DL 100-300mm (it's poor on the K-70), Tamron Adaptall-2 135mm/f2.5 (great IQ), Tokina RMC 200mm/f3.5 (OK IQ but heavy and as big as the M 80-200), Sigma aspherical 20-90mm (great on low MP sensors)
6. Sell my backup body (K-m) with the old 1990s-era Sigma 18-50 and 55-200 DC lenses - I will not get much money but the lenses perform OK at 6MP, although lousy IQ on the M-70.
The dilemmas of a lens addict! I could sell a body with four or five lenses and still struggle to match the cost of one new lens. I just could not resist buying the latest. A cheaper hobby than a saltwater aquarium, or mud-jumping jeeps, at least.
