Zithunzi zochepa, zowonongeka za tizilombo ndi maluwa ndi zotheka, ngakhale, malingana ndi kukula kwa nkhaniyi, simungathe kuzigwira zonse mkati mwazithunzi. Nkhani zina zakutali, komabe, zidzakhala zoganizira kwambiri komanso zowonjezereka mwazitsulo. Mu malo oyenera, lens ili ndi malo osachepera makilomita 59, koma ndi mafilimu ambiri amagwiritsira ntchito mtundawo ukukwera mpaka masentimita 37.4. Izi zimapangitsa kukhala ndi lenti yodalirika kwa zosiyanasiyana. Ndi matembenuzidwe omwe alipo alipo ambiri a Nikon, Canon, Sony, Pentax ndi Konica Minolta DSLRs, Tamron uyu ndi mwayi waukulu kwa ojambula kwambiri pa bajeti.
Kupeza mandala osakanikirana bwino si kophweka. Pali njira zambiri zowonjezera, koma ndizochepa zokha monga Sigma 24-105mm F4.0 DG OS HSM lens kwa Canon (Nikon ndi Sony mitundu ikupezeka).

Pa makilogalamu 1.2 okha, disolo liri lokwanira mokwanira kuti likhoza kukhala mu thumba la kamera popanda kutenga malo owonjezera kapena kuwonjezera kulemera kwake.
Sigma imatengedwa kuti ndi imodzi mwa opanga makina opanga makina opanga makina opanga makina, ndipo makamaka ndiyo yaikulu kwambiri yopanga makina opangira lens padziko lapansi. Amadalirika kuti apange lensali yokhazikika, yodalirika kwa makamera osiyanasiyana ndi zolinga zowombera, ndipo izi ndizomwe zimakhala zosiyana kwambiri. Pogwiritsa ntchito 10-20mm, mumadziwa kuti izi zimapangitsa kuti muzitha kumanga nyumba zambiri, zipinda zazikulu komanso zina zazikulu. Ambiri amagwiritsidwa ntchito popanga zomangamanga, pamutu-malo aakulu ndi zamkati. Zimapereka chidwi mwamsanga, makonzedwe olondola, kumanga mwamphamvu ndi kokongola komanso kubereka mtundu wokongola. Mavesi a lens ili akhoza kujambula makamera a Canon, Nikon, Pentax ndi Sony DSLR.

Kuphatikiza bukuli kuchokera ku Tamron kumapangitsa zotsatira zochititsa chidwi ngakhale pamene zovuta za wojambula zithunzi zimakhala zochepa. Poyesa kusiyana kwakukulu kuposa ma lens ena mu kalasi yake, Tamron inalinganiziridwa kuti iganizire ntchito zabwino kwambiri ndikupereka zochitika zopanda mantha panthawi yonse yomwe ikugwira ntchito yofulumira.
Imodzi mwazitali kwambiri komanso zowona kwambiri zowonjezera zamakono zilipo, Tokina 11-16mm f / 2.8 AT-X116 ndiyenera kugula kwa amamera a kanon. Pogwiritsa ntchito bat, mungazindikire kuti mulibe vuto lokonzekera bwino, koma pali zovuta zambiri zomwe mungaphonye mbaliyi yomwe inapatsidwa f / 2.8 kutalika ndi kutalika kwa Tokina. Mwamwayi, ndi pamene zovuta zimatha. Chizindikiro cha Tokina ndi luso lochititsa chidwi kwambiri lomwe limachita bwino kwambiri poyera, chifukwa cha kutsika kwakukulu komwe kumachepetsa mpweya, makamaka pogwiritsa ntchito mphamvu zowoneka bwino.
Chizindikiro cha Tokina cha 11-16mm sichikusiya zojambula zambiri kuti zigwirizane nazo, koma pali kuzungulira kokwanira kuti zowonjezerapo zowonongeka pamphepete mwa chimango pomwe mukugogomezera phunziroli. Kulemera kwa mapaundi 1.2 okha, Tokina ndi lenti yowonjezera yowonjezera yomwe ili yabwino kwa kuyenda-kwenda kapena kumangokwanira mokwanira kunyamula dera lozungulira.
