distantele focale pentru aparatul digital ar trebui sa fie echivalentul 150-450mm la SLR(35mm)? Confused Confused

Pe Nikon, da. Pe Canon, ceva mai mult (se înmulţeşte cu 1.6, că e o idee mai mic senzorul), 160-480.

Nu o am, dar din teste si pareri pe nikanon, concluzia e cam una singura: ceva mai bun nu exista la caracteristicile si banii astia... Adica putin sub 1000$. Poate un 300/4 second hand.
Poti vedea si pe tabelul meu din foto-tehnica, cam cum sta situatia la focalele astea. Tot ce e prin jur este ori 5.6, ori 2.8, duble ca greutate si pret.
Problema e sa o gasesti, e out of stock peste tot.

Hehe... la Photokina era expus (printre un maldar de alte obiective).
Tind sa-i cred pe cei ce spun ca optic e superb, constructia e teapana desi nu-i weather sealed iar AF-ul, hmm... sa zicem ca ar fi fain sa scoata o versiune HSM.
Daca puteti, asteptati sa vedeti care-i treaba cu 60-250-ul Pentax.

Ala-i pretul de lista, care cu siguranta o sa scada in timp (cat de repede? Depinde de cerere, foarte multi pentaxisti il asteapta; si de asemenea de capacitatea de productie rezervata).
Sigma-ul se invarte la aprox. 1000 de euro, sarind in multe locuri de 1100 (cautare pe idealo.de).
