Naphezu kwenkathi engenasibuko yemakethe yamakhamera wesistimu, amamodeli akudala e-DSLR ayaqhubeka nokuba yimikhiqizo ebaluleke kakhulu nedumile ezinkampanini ezifana ne-Nikon neCanon. Eyamuva iyaqhubeka nokwehlisa iminikelo yayo ye-DSLR futhi yembule ikhamera ye-DSLR elula kunazo zonke futhi ehlangene kakhulu enesibonisi esiveza obala, i-EOS 250D (EOS Rebel SL3 noma i-EOS 200D II kwezinye izimakethe).
Ngobukhulu bomzimba (ngaphandle kwelensi) ye-122,4 Γ 92,6 Γ 69,8 mm kuphela, imodeli inesisindo esingamagremu angu-449 (kuhlanganise nebhethri nekhadi le-SDXC). Izici zifana kakhulu nekhamera engenazibuko yeCanon EOS M50. Le khamera ifaka inzwa ye-APS-C engu-24,1-megapixel efanayo, iphrosesa ye-DIGIC 8, isikrini sokuthinta esingu-3,0-intshi esiphendulwe phezulu sabathandi be-vlogging kanye ne-self-portrait, kanye nokwesekwa kwamavidiyo angu-4K (okunemikhawulo ebaluleke kakhulu). Okubaluleke kakhulu, lena imodeli yokuqala yeCanon EOS ukufaka i-Dual Pixel CMOS AF kanye ne-Eye Detection ku-Live View (amaphoyinti angu-143 e-AF azenzakalelayo).
Abathwebuli bezithombe abangochwepheshe bavame ukukhetha amakhamera edijithali e-SLR, asebenzisa amasistimu okuthola i-autofocus ehlukene, kwesinye isikhathi awavumela ukuthi athwebule izifundo ngokushesha kunamakhamera angenazibuko. I-250D inikeza isistimu yokubona enamaphuzu angu-9 AF uma uthwebula ngesitholi sokubuka esibonakalayo.
Ukwengeza, kunesistimu ye-Canon eshiwo ngenhla ye-Dual Pixel eyakhelwe ngqo kunzwa, ehlinzeka nge-autofocus esheshayo nenembile yevidiyo engu-1080p nokushuthwa Kwesithombe Esibukhoma. Noma kungasheshi kangako, khona kanye ukuba khona kokulandela i-autofocus sekuvele kuyinhlanganisela enkulu yekhamera yebhajethi ye-DSLR.
I-EOS 250D futhi iyikhamera yokuqala yeCanon ekilasini layo ukusekela ukushuthwa kwevidiyo okungu-4K (25fps). Ngeshwa, kule modi, awukwazi ukusebenzisa amaphikseli okuthola isigaba akhelwe kunzwa yesithombe, kodwa kufanele uthembele kuphela ekugxilweni okuzenzakalelayo kokugqamayo. Lokhu kubukela phansi kakhulu amandla e-autofocus nokushuthwa kwevidiyo.
Ngaphezu kwalokho, ulwazi alubanjwanga kuyo yonke inzwa, kodwa kusukela ku-1,6 izikhathi ezisikiwe, njengaku-EOS M50, okuholela kusayizi wenzwa osebenzayo omncane kunalowo wamakhamera we-Micro Four Thirds. ICanon 250D nayo ayinakho ukuzinza kwemishini okwakhelwe emzimbeni (ukuzinza kwe-optical kutholakala kuphela kumalensi ahambisanayo), futhi uma uthwebula ividiyo kusebenzisa ukuzinza kwedijithali, okwethula uhlaka olungeziwe. Amavidiyo angarekhodwa kuze kube yimizuzu engama-30 ubude.
Ngokwamanye ama-specs, idivayisi inikeza ukuthwebula kwezithombe okungu-5fps, ububanzi be-ISO obufika ku-25 (inwetshwe kufika ku-600), kanye nebhethri elikwazi ukuthwebula izithombe ezinkulu eziyi-51 ngeshaji eyodwa (200 ku-Live View). Yebo, kanye ne-JPEG, ukudubula ngefomethi ye-RAW engu-1600-bit (inguqulo yesithathu evela kuCanon) kuyasekelwa.
Kukhona usekelo olwakhelwe ngaphakathi lwe-Wi-Fi 802.11n, i-Bluetooth LE, imiphumela ye-PAL/NTSC (ehlanganiswe ne-USB), i-mini-HDMI, isixhumi sezicathulo ezishisayo sokukhanyisa kwangaphandle, kanye nembobo ye-stereo engu-3,5mm yombhobho wangaphandle. Ibhokisi lihlanganisa ikhamera ngokwayo, i-EF Eyecup, i-RF-3 Camera Body Cap, i-EW-400D-N Wide Strap, i-LC-E17E Ishaja, i-LP-E17 Battery, Power Cord, ne-User Manual.
Kukhona kokubili izilungiselelo ezenziwa ngesandla kanye nenqwaba yezinhlelo ezizenzakalelayo, okuhlanganisa imodi "Yomsizi Wokudala", eklanyelwe ukunikeza abasaqalayo amathiphu okuvula amandla ekhamera. Izigcawu ezintsha ezikhethekile zifaka phakathi "isikhumba esibushelelezi," ngokusobala esidizayinelwe ukuzimelela ngobude.
ICanon EOS 250D izotholakala ekupheleni kuka-April ngo-$600 (US) noma ngo-$750 nge-EF-S 18-55mm f/4-5,6 IS lens. Itholakala ngezinguqulo ezimnyama nesiliva. Ngale ntengo, imbangi yayo eseduze cishe yi-$3500 D500 DSLR, futhi naphezu kwemikhawulo ye-4K eshiwo ngenhla, i-250D ibukeka ingcono kakhulu ngezindleko eziphakeme kancane.
