28/2.8
The total quality of this objective is much high, comparable one to the best normal schools from 50mm. Optical therefore of professional level without some limitation for the quality. Advanced price to the average but wide justified from the caught up performances

21/2.8
Objective with one rendered to esamplare. Clearness to the excellent center, to the edges can be defined sbalorditiva considering the short focale. Also to the maximum opening it works dearly. Distortion of 3 % is from considering contained. Optimal the vignettatura and the precision of the diaphragm.

25/2.8
The total clearness is acceptable but there is an enormous difference between center and edges: to the center it is always much high one (except to all opening) while to the edges it is practically always rather low. Although it is a not difficult objective in terms of focale and opening is decidedly under tone for being one Zeiss, with a decidedly high price being turned professionals. Good the correction of the distortion, insufficient that one of the vignettatura and hardly sufficient the precision of the diaphragm. (TF 7/98)

35/1.4
the clearness from 5,6 in then is good, but leggermente inferior to that one of the 35 f/2.8 the much less expensive one. E' to 1,4 that this objective is splendid in how much succeeds to naturally maintain one highest uniformita between center and edges even if to one rendered inferior regarding diaphragms + sluices. E' therefore an optimized objective in order to work in conditions of insufficient light. Distortion and diaphragm very are corrected. The vignettatura is rather obvious to 1,4 but similar opening is natural for one.

35/2.8
Zeiss remains faithful to its optical choice, guaranteeing to whichever focale attempts one truly elevated standard. The price also in this case more is elevated of the average, however still accessible it is to the professional who to the amatore. Perhaps migliorabile the correction of the distortion and the vignettatura.

50/1.7
Optimal, advanced objective, if also of least, to greater brother 1.4 to which it goes preferred in case it is not necessary to work to 1,4 the price is more than approachable. It is advised lively also to the possessory ones of Yashica cameras like substitute of Yashica 50/1.7 or 50/1,9

50/1.4
Optimal objective with one splendid clearness. In spite of the optimal level of present correction in the Zeiss, the maximum opening has however a low level of clearness and therefore goes only used in the cases of effective necessity. Saying goes that second some the point strongly of this objective is its plasticity and ariosita, both not noticeable from no test.

85/1.2
The optical quality is excellent. Also the vignettatura, sure visible, must be considered very corrected in onsiderazione of the exceptional relative opening. This objective has been produced in a reduced exemplary number in occasion of the 60 years of life of the Contax brand, resuming the glorious outline of Planar 85 f/1.2. E' be moreover improved mechanically with the introduction of the commando MILIMETER for having the compatibility with the Contax new. (TF 5/95)

85/1.4
draft of a objective that ago honor to the Zeiss name, and that confirmation the opinion of many photographers professionals, than it define the ideal objective for the ritratto one. In fact the maximum incisivita is present to the center, where the important part of the subject comes to place itself. The background, and therefore the edges, intentionally turn out in kind outside fire and appear therefore the little important. To intermediate diaphragms, if we search the clearness on all the photogram, we have the highest one rendered from the center to the edges. The clearness extremely elevated also to the maximum openings of it guarantees an extreme versatilita of employment. Good the vignettatura, solo the 0.75 diaphragm, considered brightness of the optical. The price, leggermente advanced to that one of the contenders, however is justified from the optimal performances.

100/2
there is little from saying: it is an excellent objective, best the 100 f/2 in commerce. The price is highest, beyond 4 million. (TF 2/94)

135/2
the Contax Zeiss Planar T * MILIMETER Anniversary 135 f/2 is an excellent objective, best the 135 in commerce. Unfortunately it is extremely expensive and of difficult reperibilita, in how much the special series 60 Contax Years by now is exausted. It can be reperito single near collectors. (TF 2/94)

135/2.8
Objective with characteristics not exasperated, but of optimal quality, species to the maximum opening of the diaphragm. Perfectly under control distortion, vignettatura and precision of the diaphragm. The price is all added content, considered the average of the Contax prices. (TF 5/95)

180/2.8
draft of an optimal objective, even if could supply something in more is as far as the clearness (suffers from simple an optical outline and from the absence of important glasses to low dispersion in questelunghe focali), is for the correction of the distortion. The price is then an elevated Po more of the average of i 180 milimeter of equal opening.
